Explanation:

Herbivores are organisms that feeds on plants. Herbivores range in size from tiny insects such as aphids to large, lumbering elephants.

Herbivores are a major part of the food web, organisms in the food web are grouped into trophic, levels. These are: 1) Autotrophs(producer): They are organisms that produce their own food. These include plants and ALGAE.

2) Herbivores(primary consumer): They consist of organisms that feeds on autotrophs.

2) Carnivores(secondary consumer): They consist of organisms that consume animals, and omnivores organisms that consume both plants and animals.

Some herbivores consume only dead plant material. These organisms are called DETRITIVORES. Detritivores also consume other dead organic material, such as decaying animals, fungi, and ALGAE. Detritivores such as earthworms, bacteria, and fungi are an important part of the food chain.
