Question

which phrase is an example of autotrophic nutrition?

1. a cow eating grass in a field
2. a mushroom digesting a dead log
3. an apple tree making its own food
4. a tapeworm feeding in the body of a dog

Explanation:

Autotrophic nutrition is when an organism makes its own food. A cow is a heterotroph (eats other organisms - grass). A mushroom is a decomposer (heterotroph - digests dead organic matter). A tapeworm is a parasite (heterotroph - feeds off a host - the dog). An apple tree is a plant that can perform photosynthesis (make its own food) which is autotrophic nutrition.

Answer:

1. an apple tree making its own food
