Environment

Correct answer: C

I is incorrect: Secondary succession → Succession where soil remains after disturbance. Recovery after a field is abandoned is an example. II is incorrect: Carrying capacity → Population supportable over time under given conditions. It depends on resources and environmental limits.

Correct answer: A

I is correct: Habitat → Place where an organism lives. Habitat describes location and environmental setting. II is correct: Ecotone → Transition zone between ecological communities. It may contain species from adjoining communities.

Correct answer: B

It spans parts of land, water and atmosphere.

Correct answer: A

I is correct: Biotic factor → Living influence within an ecosystem. Predators, competitors and pathogens are examples. II is incorrect: Ecological niche → An organism's functional role and resource use. A niche is more than its physical address.

Correct answer: B

New lava provides a possible starting surface.

Correct answer: A

I is correct: Limiting factor → Resource or condition restricting growth. Scarce water can limit plant production. II is correct: Population → Individuals of one species in a defined area. Population size and density concern a single species.

Correct answer: C

I is incorrect: Ecosystem → Community together with its physical environment. It includes both biotic and abiotic components. II is correct: Carrying capacity → Population supportable over time under given conditions. It depends on resources and environmental limits.

Correct answer: D

Habitat describes location and environmental setting.

Correct answer: C

I is correct: Biosphere → Earth's zone supporting life. It spans parts of land, water and atmosphere. II is correct: Ecotone → Transition zone between ecological communities. It may contain species from adjoining communities.

Correct answer: A

Recovery after a field is abandoned is an example.

Correct answer: B

I is correct: Community → Populations of different species living together. A community includes interacting living populations. II is incorrect: Ecosystem → Community together with its physical environment. It includes both biotic and abiotic components.

Correct answer: D

Tundra and tropical rainforest are examples.

Correct answer: A

I is incorrect: Abiotic factor → Non-living environmental component. Temperature, light and mineral availability are examples. II is correct: Primary succession → Succession on a surface initially lacking developed soil. New lava provides a possible starting surface.

Correct answer: D

Population size and density concern a single species.

Correct answer: B

I is incorrect: Habitat → Place where an organism lives. Habitat describes location and environmental setting. II is correct: Secondary succession → Succession where soil remains after disturbance. Recovery after a field is abandoned is an example.

Correct answer: A

A community includes interacting living populations.

Correct answer: D

I is correct: Abiotic factor → Non-living environmental component. Temperature, light and mineral availability are examples. II is correct: Biosphere → Earth's zone supporting life. It spans parts of land, water and atmosphere.

Correct answer: A

It may contain species from adjoining communities.

Correct answer: D

I is incorrect: Biome → Large ecological region associated with climate and vegetation. Tundra and tropical rainforest are examples. II is incorrect: Limiting factor → Resource or condition restricting growth. Scarce water can limit plant production.

Correct answer: B

It includes both biotic and abiotic components.

Correct answer: A

I is incorrect: Community → Populations of different species living together. A community includes interacting living populations. II is incorrect: Ecological succession → Change in community composition over time. It can follow disturbance or colonisation of new surfaces.

Correct answer: B

Scarce water can limit plant production.

Correct answer: D

I is incorrect: Biosphere → Earth's zone supporting life. It spans parts of land, water and atmosphere. II is incorrect: Population → Individuals of one species in a defined area. Population size and density concern a single species.
