Question

where do producers get matter?
a. soil
b. the sun
c. other organisms
d. carbon dioxide and water

Explanation:

Producers (like plants) perform photosynthesis. In photosynthesis, they use carbon dioxide (from the air) and water (from the environment) to make glucose (a form of matter) and oxygen. Soil provides some nutrients but not the main matter for building organic compounds. The sun provides energy, not matter. Producers don't get matter from other organisms (that's consumers). So the correct source of matter for producers is carbon dioxide and water.

Answer:

D. carbon dioxide and water
