Questions and Answers
- 2.
What are the 8 characteristics that living things have to have in order to be considered living?
- 3.
The combination of chemical reactions through which an organism breaks down or builds up materials as it lives is____________.
Explanation
Metabolism refers to the combination of chemical reactions in an organism that involve the breakdown or buildup of materials as it carries out its life functions. It is the process by which the body converts food and drinks into energy that is used to perform various activities. Metabolism is essential for maintaining life and regulating bodily functions such as digestion, respiration, and circulation.Rate this question:

What is homeostasis?
-
When an organism reacts to its environment
-
When an organism adapts as it lives on
-
When an organism keeps its internal conditions stable
-
When an organism feeds on another organism
Correct Answer
A. When an organism keeps its internal conditions stableExplanation
Homeostasis refers to the process by which an organism maintains a stable internal environment despite changes in the external environment. This includes regulating factors such as body temperature, pH levels, and nutrient levels within certain limits. By keeping its internal conditions stable, an organism can ensure that its cells and systems function properly, allowing it to survive and thrive in its environment. The other options, such as reacting to the environment, adapting, or feeding on another organism, do not accurately describe the concept of homeostasis.Rate this question:

How much does the biosphere extend above earths surface?
-
25 kilometers
-
6 inches
-
8 kilometers
-
6 kilometers
Correct Answer
A. 8 kilometersExplanation
The biosphere extends approximately 8 kilometers above the Earth's surface. The biosphere refers to the zone on Earth where life exists, including the land, water, and atmosphere. It encompasses all ecosystems and organisms, from the deepest parts of the ocean to the highest mountains. The 8-kilometer measurement indicates the vertical extent of the biosphere, suggesting that life can be found up to this height above the Earth's surface.Rate this question:

What are species?
-
A group of organisms so similar to one another that they can breed and produce fertile offspring.
-
A group of individuals that belong to the same species and live in the same area
-
A assemblages or different populations that live together in a defined area
Correct Answer
A. A group of organisms so similar to one another that they can breed and produce fertile offspring.Explanation
Species are defined as a group of organisms that share similar characteristics and are capable of interbreeding to produce fertile offspring. This definition is based on the concept of reproductive isolation, where individuals within a species can mate and produce viable offspring, while individuals from different species cannot. This reproductive compatibility is a key factor in distinguishing one species from another. The other options provided in the question, such as a group of individuals belonging to the same species or different populations living together, do not fully capture the concept of species and the ability to produce fertile offspring.Rate this question:

What is an ecosystem?
-

-
A collection of all organisms that live in a particular place, together with their nonliving, or physical, environment
Correct Answer
A. A collection of all organisms that live in a particular place, together with their nonliving, or physical, environmentExplanation
An ecosystem refers to a collection of all organisms, including plants, animals, and microorganisms, that exist in a specific location. This also includes their nonliving surroundings, such as the air, water, soil, and physical features of the environment. The organisms within an ecosystem interact with each other and with their environment, forming a complex web of relationships and dependencies. This definition highlights the interconnectedness and interdependence of living organisms and their physical surroundings within a specific area.Rate this question:

-
Groups of individuals that belong to the same species and live in the same area
-
A valley
Correct Answer
A. Groups of individuals that belong to the same species and live in the same areaExplanation
The correct answer is "groups of individuals that belong to the same species and live in the same area". Population refers to a collection of individuals of the same species that inhabit a specific geographic area. This definition emphasizes the idea that populations consist of multiple individuals of the same species who interact and share a common environment.Rate this question:

-
Assemblages or different populations that live together in a defined area
Correct Answer
A. Assemblages or different populations that live together in a defined areaExplanation
Community refers to a group of assemblages or different populations that coexist and interact with each other in a specific and defined geographical area. It implies the presence of various organisms or individuals living together and sharing resources within a particular ecosystem or habitat. This definition highlights the concept of interdependence and mutual relationships among different species in a given area.Rate this question:

What does biome mean?
-
The study of earth
-
A earth-like dome
-
A group of ecosystems that have the same climate and similar dominant communities
Correct Answer
A. A group of ecosystems that have the same climate and similar dominant communitiesExplanation
Biome refers to a group of ecosystems that share the same climate and have similar dominant communities. It is a term used in ecology to categorize and describe large-scale ecological communities. Biomes are characterized by their distinct climate, vegetation, and animal life, and they can be found across different regions of the world. This definition aligns with the given answer choice, which accurately describes the concept of biome.Rate this question:

In figure 3-3 ecologists are studying a rain forest ecosystem. Where are they studying the rain forest ecosystem?
-
Sri Lanka
-
Paris
-
Italy
-
Amazon Rain forest
Correct Answer
A. Sri LankaExplanation
The correct answer is Sri Lanka because the question states that the ecologists are studying a rainforest ecosystem, and Sri Lanka is mentioned as one of the options. Therefore, it can be inferred that the ecologists are studying the rainforest ecosystem in Sri Lanka.Rate this question:

-
Physical or nonliving factors that shape ecosystems
Correct Answer
A. Physical or nonliving factors that shape ecosystemsExplanation
Abiotic factors refer to physical or nonliving components that influence and shape ecosystems. These factors include elements such as temperature, sunlight, water availability, soil composition, and air quality. They play a crucial role in determining the types of organisms that can survive in a particular environment and the overall functioning of the ecosystem. By understanding and studying abiotic factors, scientists can gain insights into the relationships between organisms and their environment and how ecosystems respond to changes in these factors.Rate this question:

The biological influences on organisms within an ecosystem
Correct Answer
A. The biological influences on organisms within an ecosystemExplanation
Biotic factors refer to the living components of an ecosystem that have an impact on organisms. These factors include interactions between organisms such as predation, competition, and symbiosis, as well as the availability of food, shelter, and resources. Biotic factors play a crucial role in shaping the structure and dynamics of ecosystems, as they determine the survival, growth, and reproduction of organisms within a given environment.Rate this question:

The full range of physical and biological conditions in which an organism lives and the way in which the organism uses those conditions
Correct Answer
A. The full range of physical and biological conditions in which an organism lives and the way in which the organism uses those conditionsExplanation
Niche refers to the complete range of physical and biological conditions in which an organism lives, as well as the specific way in which the organism utilizes those conditions. It encompasses the habitat, resources, and interactions that are essential for the survival and reproduction of a particular species. The concept of niche highlights the unique role or function that an organism plays within its ecosystem, including its interactions with other species and its adaptation to its environment.Rate this question:
