D) The first level includes autotrophs, the next three levels include primary consumers, carnivores, and omnivores, and the last level includes detritivores and decomposer 2. How are decomposers involved in the food chain? A) They complete the food chain by returning nutrients for autotrophs to use. B) The begin the food chain by turning sunlight, air, soil or water into food. C) They eat the producers in the first level of the food chain. D) They eat the herbivores in the second level of the ood chain. - How do tertiary consumers primarily get their mergy? ) They eat secondary consumers that eat primary nsumers.

B) Decomposers make up the first level chain since they make their own food. C) Decomposers give nutrients to the autotrophs can use the nutrients. D) Decomposers are able to eat both plant​

Answer 1

3. A) They eat secondary consumers that eat primary consumers.

4. C) Omnivores eat both plants and animals, while herbivores eat only plants.

5. D) Producers make food using photosynthesis.

6. C) Decomposers give nutrients to the autotrophs so they can use the nutrients.
