Trivia Quiz On Ecology Nutrient Cycles And Succession!
(30).jpg "Trivia Quiz On Ecology Nutrient Cycles And Succession! - Quiz")
A nutrient cycle is the unending movement of nutrients from the physical ecosystem into a living organism, and then it goes back into the physical environment. The health of the ecosystem depends on this. An ecological sequence is the procedure of change in the species structure of an ecological community over time. This quiz is all about ecology, nutrient cycles, and succession. You can do it.
- 1.
In a nutrient cycle, nutrients are
- A.
Recycled constantly
- B.
Put in long term storage occasionally in nutrient "sinks"
- C.
Put in temporary storage in the bodies of organisms
- D.
All of the above
Correct Answer
D. All of the aboveExplanation
In a nutrient cycle, nutrients go through a continuous process of being recycled. They are taken up by organisms, stored temporarily in their bodies, and then released back into the environment through various means such as decomposition or excretion. Additionally, nutrients can also be stored in long-term storage areas known as nutrient "sinks" such as soil or bodies of water. Therefore, all of the given options are correct as they describe different aspects of how nutrients are cycled in an ecosystem.Rate this question:

Food chains are included in nutrient cycles because
- A.
Only plants uptake nutrients from non-living systems.
- B.
Nutrient cycles occur entirely inside food chains.
- C.
Consumers get their nutrients through their food (producers or other consumers).
- D.
Both A and C.
Correct Answer
D. Both A and C.Explanation
Food chains are included in nutrient cycles because both plants and consumers play a role in the uptake and transfer of nutrients. Plants uptake nutrients from non-living systems, such as soil or water, and convert them into organic matter through photosynthesis. Consumers, including both producers and other consumers, obtain their nutrients by consuming plants or other organisms. This creates a cycle where nutrients are transferred from one organism to another, ultimately returning to the non-living systems through decomposition and nutrient release. Therefore, both options A and C are correct.Rate this question:

A nutrient cycle reservoir is a place where
- A.
The nutrient is stored for a long time
- B.
The nutrient is stored for a short time
- C.
The nutrient is stored forever
- D.
Can be A or B
Correct Answer
D. Can be A or BExplanation
A nutrient cycle reservoir can be a place where the nutrient is stored for a long time or for a short time. This suggests that it can vary depending on the specific nutrient and the reservoir in question. Some nutrients may be stored in reservoirs for extended periods, while others may be stored for shorter durations. Therefore, the correct answer is that it can be either A or B, depending on the circumstances.Rate this question:

Eutrophication is the situation where
- A.
A water body is made really nice with extra nutrients
- B.
A water body is destroyed by excess nutrients like nitrogen or phosphorus
- C.
A piece of land is over fertilized
- D.
The atmospheric reservoir receives too much carbon and it traps more heat
Correct Answer
B. A water body is destroyed by excess nutrients like nitrogen or pHospHorusExplanation
Eutrophication is the situation where a water body is destroyed by excess nutrients like nitrogen or phosphorus. This occurs when these nutrients enter the water body from sources such as agricultural runoff or sewage. The excess nutrients cause an overgrowth of algae and other aquatic plants, leading to a decrease in oxygen levels in the water. This can result in the death of fish and other aquatic organisms, as well as the degradation of the overall ecosystem of the water body.Rate this question:

The Enhanced Greenhouse Effect is a problem that occurs when
- A.
A water body is destroyed by excess nutrients like nitrogen or phosphorus
- B.
A piece of land is over fertilized
- C.
A greenhouse plant receives too much fertilizer
- D.
The atmospheric reservoir receives too much carbon and it traps more heat
Correct Answer
D. The atmospHeric reservoir receives too much carbon and it traps more heatExplanation
The enhanced greenhouse effect refers to the phenomenon where the atmospheric reservoir, such as the Earth's atmosphere, receives an excessive amount of carbon and as a result, it traps more heat. This occurs due to the increased concentration of greenhouse gases, such as carbon dioxide, in the atmosphere. These gases act like a blanket, preventing the escape of heat from the Earth's surface into space, leading to a rise in global temperatures.Rate this question:

The term "Cycle" is used in Nutrient cycles because.
- A.
They have two parts like the two wheels of a "Bicycle"
- B.
Their steps always form a long ring, like a snake biting its tail
- C.
The nutrients always get cycled and recycled, through the many paths of the system.
Correct Answer
C. The nutrients always get cycled and recycled, through the many paths of the system.Explanation
The correct answer is "The nutrients always get cycled and recycled, through the many paths of the system." This answer is supported by the concept of nutrient cycles, which involve the movement and transformation of nutrients through different components of an ecosystem. Nutrients are constantly being taken up by organisms, released back into the environment through various processes such as decomposition, and then taken up again by other organisms. This continuous cycling and recycling of nutrients ensures that they are available for different organisms and helps maintain the balance of the ecosystem.Rate this question:

Succession in ecology refers to...
- A.
Who will be the next king of the food chain
- B.
A series of organisms that move into an ecosystem one after the other.
- C.
The first organisms into a new ecosystem.
- D.
Who is able to survive successfully.
Correct Answer
B. A series of organisms that move into an ecosystem one after the other.Explanation
Succession in ecology refers to a series of organisms that move into an ecosystem one after the other. It is the process by which the structure and composition of a community of organisms change over time. As one group of organisms establishes itself in an ecosystem, it creates conditions that allow for the colonization of new species. These new species then replace the initial ones, leading to a gradual change in the community. This process continues until a stable and mature community, known as a climax community, is reached.Rate this question:

The first organisms to more into an area of new rock would probably be
- A.
Trees
- B.
Shrubs
- C.
Grasses
- D.
Lichens & Mosses
Correct Answer
D. Lichens & MossesExplanation
Lichens and mosses are the correct answer because they are pioneer species, meaning they are the first organisms to colonize a new area. They are able to grow on bare rock surfaces and can survive in harsh conditions. Lichens are a symbiotic relationship between fungi and algae, allowing them to break down rock and create soil. Mosses, on the other hand, can absorb water and nutrients from the environment and help create a suitable habitat for other plants to grow. Therefore, lichens and mosses are the first organisms to establish themselves on new rock surfaces.Rate this question:

The following would be examples where Primary Succession would occur
- A.
A volcanic island appears in the middle of the ocean.
- B.
A forest fire destroys growing plants for several square miles.
- C.
A construction crew bulldozes a path through bush and then abandons the project.
- D.
A volcano erupts and flowing lava covers the entire side of the mountain.
- E.
A and D
- F.
B and C
Correct Answer
E. A and DExplanation
Primary succession occurs in areas where there is no existing soil or vegetation. In the given examples, both a volcanic island appearing in the middle of the ocean and a volcano erupting and covering the entire side of a mountain with flowing lava would result in the creation of new land without any pre-existing soil or vegetation. Therefore, these examples would be instances where primary succession would occur.Rate this question:

The following would be examples where Secondary Succession would occur.
- A.
A flood deposits a large amount of mud on top of several square miles.
- B.
After a nuclear disaster at Chernobyl all humans abandon the city.
- C.
A volcano dumps a 3ft thick layer of ash over an entire mountain.
- D.
A and B
Correct Answer
D. A and BExplanation
Secondary succession occurs when an existing ecosystem is disturbed or destroyed, but the soil remains intact. In the given examples, both a flood depositing mud and a nuclear disaster causing humans to abandon the city would result in the existing vegetation being destroyed, but the soil would still be present. This allows for the process of secondary succession to take place, where new plant species gradually colonize the area and the ecosystem begins to recover. In contrast, the volcano dumping ash over a mountain would be an example of primary succession, as the ash would completely sterilize the soil and require the ecosystem to start from scratch.Rate this question:
-
- 13.
Primary Succession is a much faster process than Secondary Succession
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
Primary succession is a slower process compared to secondary succession. Primary succession occurs in areas where there is no existing soil, such as on bare rock or after a volcanic eruption. It involves the gradual formation of soil and the colonization of pioneer species, which eventually leads to the establishment of a stable ecosystem. In contrast, secondary succession occurs in areas where there is already soil present, such as after a forest fire or clear-cutting. The process of secondary succession is faster because the soil already contains nutrients and microorganisms that can support plant growth.Rate this question:
-
- 14.
Secondary Succession can be slowed down a lot if the disturbance includes major soil erosion.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
If a disturbance includes major soil erosion, it can significantly slow down secondary succession. This is because soil erosion removes the top layer of soil, which contains important nutrients and organic matter necessary for plant growth. Without these nutrients, it becomes difficult for plants to establish and grow, thus slowing down the process of secondary succession.Rate this question:
-
- 15.
Animals can speed up Primary Succession by carrying seeds and other materials into a brand new area of ground.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
Animals can speed up primary succession by carrying seeds and other materials into a brand new area of ground. This is because animals play a crucial role in seed dispersal. They consume fruits and plants and then excrete the seeds in different locations, allowing for the colonization of new areas. Additionally, animals can also transport seeds and other materials on their fur or feathers, further aiding in the establishment of new plant communities. Therefore, the statement "True" is correct.Rate this question:
-

It can take hundreds of years to replace a couple of inches of topsoil in some ecosystems.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
This statement suggests that the process of replacing a small amount of topsoil in certain ecosystems can be a very slow one, taking hundreds of years. This implies that the formation and accumulation of topsoil is a gradual and time-consuming process, making the statement true.Rate this question:
-
- 17.
Humans never have any influence on the rates of Succession, Primary or Secondary.
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
Humans do have influence on the rates of Succession, Primary or Secondary. Human activities such as deforestation, urbanization, and agriculture can disrupt natural ecosystems and alter the process of succession. Additionally, humans can also initiate secondary succession by clearing land for agriculture or development. Therefore, the statement that humans never have any influence on the rates of succession is incorrect.Rate this question:
