What is the primary goal of conservation biology?

  1. To protect and restore biodiversity

  2. To manage natural resources sustainably

  3. To study the interactions between species and their environment

  4. To develop new technologies for environmental conservation


Correct Option: A
Explanation:

Conservation biology is the scientific study of the conservation of biodiversity, the variety of life on Earth, including species, ecosystems, and genetic variation.

What are the main threats to biodiversity?

  1. Habitat loss and fragmentation

  2. Climate change

  3. Pollution

  4. Invasive species

  5. All of the above


Correct Option: E
Explanation:

Habitat loss and fragmentation, climate change, pollution, and invasive species are all major threats to biodiversity.

What is the difference between a species and an ecosystem?

  1. A species is a group of organisms that can interbreed, while an ecosystem is a community of living organisms in conjunction with the nonliving components of their environment (things like air, water and soil), interacting as a system.

  2. A species is a group of organisms that share a common ancestor, while an ecosystem is a community of living organisms in conjunction with the nonliving components of their environment (things like air, water and soil), interacting as a system.

  3. A species is a group of organisms that live in the same area, while an ecosystem is a community of living organisms in conjunction with the nonliving components of their environment (things like air, water and soil), interacting as a system.

  4. A species is a group of organisms that have similar characteristics, while an ecosystem is a community of living organisms in conjunction with the nonliving components of their environment (things like air, water and soil), interacting as a system.


Correct Option: A
Explanation:

A species is a group of organisms that can interbreed, while an ecosystem is a community of living organisms in conjunction with the nonliving components of their environment (things like air, water and soil), interacting as a system.

What is the role of keystone species in an ecosystem?

  1. Keystone species are species that have a disproportionately large impact on their ecosystem relative to their abundance.

  2. Keystone species are species that are essential for the survival of other species in their ecosystem.

  3. Keystone species are species that are at the top of the food chain in their ecosystem.

  4. Keystone species are species that are found in all ecosystems.


Correct Option: A
Explanation:

Keystone species are species that have a disproportionately large impact on their ecosystem relative to their abundance. They play a critical role in maintaining the structure and function of their ecosystem.

What is the concept of carrying capacity in ecology?

  1. Carrying capacity is the maximum population size of a species that an environment can sustain indefinitely, given the food, water, and other resources available.

  2. Carrying capacity is the maximum population size of a species that an environment can sustain indefinitely, given the amount of pollution that the species produces.

  3. Carrying capacity is the maximum population size of a species that an environment can sustain indefinitely, given the amount of habitat that is available.

  4. Carrying capacity is the maximum population size of a species that an environment can sustain indefinitely, given the number of predators that are present.


Correct Option: A
Explanation:

Carrying capacity is the maximum population size of a species that an environment can sustain indefinitely, given the food, water, and other resources available.

What is the difference between a food chain and a food web?

  1. A food chain is a linear sequence of organisms through which nutrients and energy pass, while a food web is a more complex network of interconnected food chains.

  2. A food chain is a linear sequence of organisms through which nutrients and energy pass, while a food web is a more complex network of interconnected food chains.

  3. A food chain is a linear sequence of organisms through which nutrients and energy pass, while a food web is a more complex network of interconnected food chains.

  4. A food chain is a linear sequence of organisms through which nutrients and energy pass, while a food web is a more complex network of interconnected food chains.


Correct Option: A,B,C,D
Explanation:

A food chain is a linear sequence of organisms through which nutrients and energy pass, while a food web is a more complex network of interconnected food chains.

What is the role of decomposers in an ecosystem?

  1. Decomposers are organisms that break down dead organic matter into simpler substances that can be used by other organisms.

  2. Decomposers are organisms that convert organic matter into inorganic matter.

  3. Decomposers are organisms that recycle nutrients back into the environment.

  4. Decomposers are organisms that help to maintain the balance of oxygen and carbon dioxide in the atmosphere.


Correct Option: A
Explanation:

Decomposers are organisms that break down dead organic matter into simpler substances that can be used by other organisms.

What is the difference between primary and secondary succession?

  1. Primary succession occurs on previously uninhabited land, while secondary succession occurs on land that has been disturbed but not completely destroyed.

  2. Primary succession occurs on previously uninhabited land, while secondary succession occurs on land that has been completely destroyed.

  3. Primary succession occurs on land that has been disturbed but not completely destroyed, while secondary succession occurs on previously uninhabited land.

  4. Primary succession occurs on land that has been completely destroyed, while secondary succession occurs on land that has been disturbed but not completely destroyed.


Correct Option: A
Explanation:

Primary succession occurs on previously uninhabited land, while secondary succession occurs on land that has been disturbed but not completely destroyed.

What is the role of fire in ecosystem management?

  1. Fire can be used to control invasive species.

  2. Fire can be used to reduce the risk of wildfires.

  3. Fire can be used to improve the quality of wildlife habitat.

  4. Fire can be used to all of the above.


Correct Option: D
Explanation:

Fire can be used to control invasive species, reduce the risk of wildfires, and improve the quality of wildlife habitat.

What is the concept of sustainable development?

  1. Sustainable development is a type of development that meets the needs of the present without compromising the ability of future generations to meet their own needs.

  2. Sustainable development is a type of development that maximizes economic growth.

  3. Sustainable development is a type of development that minimizes environmental impact.

  4. Sustainable development is a type of development that promotes social justice.


Correct Option: A
