Limits And Biodiversity Quiz

1.

What is the maximum number of individuals that an environment can support?

A.

Climax Community
B.

Carrying Capacity
C.

Biodiversity
D.

Terrestrial

Correct Answer
B. Carrying Capacity

Explanation
Carrying capacity refers to the maximum number of individuals that an environment can sustainably support. It takes into account factors such as available resources, space, and competition for survival. When the population exceeds the carrying capacity, there can be negative impacts on the environment, such as resource depletion and increased competition for limited resources. Therefore, the correct answer is carrying capacity.

Limiting Factors are

A.

The amount of stress an organism can tolerate
B.

An area in the environment that is considered stable
C.

When changes take place in the community
D.

Anything that prevents organisms from living

Correct Answer
D. Anything that prevents organisms from living

Explanation
Limiting factors are elements or conditions in the environment that restrict the growth, abundance, or distribution of organisms. They can include factors such as availability of resources, competition, predation, disease, and physical factors like temperature or pH. These factors act as barriers or limitations that prevent organisms from thriving or surviving in certain habitats. By imposing constraints on population size or distribution, limiting factors help maintain ecological balance and prevent overpopulation or extinction of species.

The process of a community that changes over time is called?

A.

Tolerance
B.

Climax community
C.

Succession
D.

Limiting factors

Correct Answer
C. Succession

Explanation
Succession refers to the process of change and development in a community over time. It involves the replacement of one community by another as a result of natural disturbances or human activities. Succession can occur in various ecosystems, such as forests, grasslands, or aquatic environments, and it typically involves a series of predictable stages leading to the establishment of a stable and mature community known as a climax community. This process is essential for the renewal and regeneration of ecosystems and plays a crucial role in maintaining biodiversity and ecological balance.

Removal of which organism would have the greatest impact on an ocean food chain?

A.

Shrimp
B.

Fish
C.

Whales
D.

Plankton

Correct Answer
D. Plankton

Explanation
Plankton is the correct answer because it serves as the primary producer in the ocean food chain. It is a crucial food source for many organisms, including shrimp, fish, and whales. Without plankton, the entire food chain would collapse, leading to a significant disruption in the ecosystem.

5.

A habitat that is damage by pollution is called?

A.

Habitat loss
B.

Habitat degredation
C.

Habitat conservation
D.

Habitat fragmentation

Correct Answer
B. Habitat degredation

Explanation
Habitat degradation refers to the deterioration or damage of a habitat due to various factors, including pollution. Pollution can negatively impact the quality and health of a habitat, leading to a decline in its ability to support the organisms that depend on it. This can result in the loss of biodiversity and disruption of ecological processes. Therefore, habitat degradation is the appropriate term to describe a habitat that is damaged by pollution.

6.

Which two factors separate the discription of biomes such as a dessert and the tropical rain forest?

A.

Temperature and altitude
B.

Temperature and precipitation
C.

Temperature and soil type
D.

Temperature and the number of organisms

Correct Answer
B. Temperature and precipitation

Explanation
The description of biomes such as a desert and the tropical rainforest is separated by temperature and precipitation. Temperature refers to the average weather conditions in a particular area, while precipitation refers to the amount of rainfall or other forms of moisture. Deserts are characterized by high temperatures and low precipitation, whereas tropical rainforests have high temperatures and high precipitation. These two factors play a crucial role in shaping the distinct characteristics and biodiversity of these biomes.

An uncut yard becomes full of bushes and shrubs and then is filled with trees to be a forest. This process is called?

A.

Aphotic zone
B.

Photic zone
C.

Tolerance
D.

Succession

Correct Answer
D. Succession

Explanation
Succession refers to the process of ecological change in an ecosystem over time. In this case, the uncut yard gradually transforms into a forest as bushes and shrubs grow and eventually give way to trees. This is a classic example of primary succession, where a barren or disturbed area is colonized by pioneer species, which are then replaced by more complex and larger organisms. Succession is an important natural process that allows ecosystems to develop and mature over time.

Rate this question:

8.

Primary succession will only occur after which event?

A.

Flooding
B.

Fire
C.

Vocanic Eruption
D.

All the above

Correct Answer
C. Vocanic Eruption

Explanation
Primary succession refers to the colonization and establishment of plant and animal life in an area that was previously devoid of life, such as bare rock or newly formed land. This process begins with the arrival of pioneer species, which are able to tolerate harsh conditions and begin the process of soil formation. A volcanic eruption can create such conditions by depositing ash and lava, which eventually break down and form soil. This makes volcanic eruptions a key event that triggers primary succession. Flooding and fire can also disrupt existing ecosystems, but they do not necessarily create the same conditions for primary succession as a volcanic eruption.

If an organism is raised in captivity and then is released into the wild where it soon dies, this is a negative example of?

A.

Biodiversity
B.

Reintroduction programs
C.

Habitat loss
D.

Over hunting

Correct Answer
B. Reintroduction programs

Explanation
This scenario is a negative example of reintroduction programs. Reintroduction programs involve raising organisms in captivity and then releasing them into the wild to restore or enhance populations. However, if the organism dies soon after release, it suggests that the reintroduction program was not successful in ensuring the survival and adaptation of the organism in its natural habitat.

Having a large number of species in one given area is called?

A.

Biodiveristy
B.

Concervation
C.

Habitat
D.

Niche

Correct Answer
A. Biodiveristy

Explanation
Biodiversity refers to the variety of species present in a specific area. It includes the diversity of plants, animals, and microorganisms, as well as the genetic diversity within each species. Having a large number of species in one area indicates high biodiversity, which is important for the overall health and stability of ecosystems. Conservation refers to the protection and management of biodiversity, habitat refers to the specific environment where a species lives, and niche refers to the role or function of a species within its habitat.

11.

One of the greatest threats to biodiversity is?

A.

Habitat loss
B.

Habitat degradation
C.

Humans
D.

All the above

Correct Answer
D. All the above

Explanation
The correct answer is "all the above" because habitat loss, habitat degradation, and human activities are all major factors contributing to the decline of biodiversity. Habitat loss occurs when natural habitats are destroyed or converted for human use, such as deforestation for agriculture or urbanization. Habitat degradation refers to the deterioration of habitats due to pollution, overexploitation, or invasive species. Humans play a significant role in causing both habitat loss and degradation through activities like land clearing, pollution, and over-harvesting. Therefore, all three options listed pose significant threats to biodiversity.

If an organism that does not belong to an area somehow moves in and begins eating all the resources, what might be the cause?

A.

They have no predators
B.

They have very low population numbers
C.

They are reproducing very slowly
D.

They only eat certain things

Correct Answer
A. They have no predators

Explanation
If an organism that does not belong to an area somehow moves in and begins eating all the resources, the cause might be that they have no predators. Without natural predators, the organism can freely consume the available resources without facing any threat or competition. This can lead to the imbalance in the ecosystem and the depletion of resources, as there are no checks and balances to control their population and consumption.
