a. ecosystems include living and nonliving things.
b. temperature and climate are not part of an ecosystem.
c. an ecosystem can be as small as a rain puddle.
d. sunlight, air, and water can be parts of an ecosystem.

b. temperature and climate are not part of an ecosystem.

Explanation:

Ecosystem refers to the interaction between the living component and non-living components of a community. Ecosystem can be in different habitats including terrestrial, aquatic etc. It is worthy to note that ecosystems vary in its size; it can be small like the rain puddle that was mentioned in the options ans it can also be as large as the largest rainforest in the world.

The non-living components, also called abiotic components of an ecosystem include nutrients, climate, temperature, soil, water, air, sunlight etc while the living or biotic components include all organisms that possess life in them e.g plants, animals, microbes etc.

Therefore, the statement that temperature and climate are not part of the ecosystem is FALSE because they are part of the abiotic components of the ecosystem.
