Explanation:

1. In a food chain, matter and energy move from one organism to another. Each organism in the food - chain represents a trophic level. A herbivore is a heterotroph that eats only plants, a carnivore preys on other heterotrophs, and an omnivore eats both plants and animals. Detritivores return nutrients to the soil, air, and water. A food web shows all possible feeding relationships at each trophic level, and biomass is the weight of living matter at a certain trophic level.

Answer:

In a food chain, matter and energy move from one organism to another. A food chain is made of several steps; each organism in the food chain represents a step called a trophic level. A(n) herbivore is a heterotroph that eats only plants, whereas a carnivore preys on other heterotrophs. A(n) omnivore eats both plants and animals. Nutrients are returned to the soil, air, and water by detritivores. A model that shows all the possible feeding relationships at each trophic level is called a food web. If you were a scientist and you wanted to determine the weight of living matter at a certain trophic level, you would measure the biomass.
