(B) they influence by a variety of factors (c)there are many types of ecosystems with unique environmental characteristics (d) only climate changes affects the shape or composition

Answer 1

Answer:

Option 'D' (  only climate changes affect the shape or composition) is correct.

Explanation:

The ecosystems are made up of all living things and the physical environment in which they interact. These biological and abiotic elements are linked by the nutrient cycle and the flow of energy. Energy enters the system by photosynthesis and is incorporated into plant tissue.

Hence, option 'D' (  only climate changes affect the shape or composition) is correct.

Answer 2

1. An ecosystem is made up of a community of organisms and their physical environment.
2. Ecosystems can be of various sizes and can be marine, aquatic, or terrestrial in nature.
3. Biomes are broad categories of terrestrial ecosystems.
4. The factors affecting the ecosystem include light, radiation, temperature, water, chemicals, gases, wind and soil. In some environments, such as marine environments, pressure and sound can be important abiotic components.
5. Thus, only climate change does not affect the shape or composition of an ecosystem.
6. Thus, the statement is incorrect.

Hence, option D is correct.
