Secondary consumer

Secondary consumers eat primary consumers. They are carnivores (meat-eaters) and omnivores (animals that eat both animals and plants). Food chains "end" with top predators, animals that have little or no natural enemies.

Third-Level consumer

third level of consumer called the tertiary consumer (that means third level). These are consumers that eat the secondary and primary consumers. A tertiary consumer could be a wolf that eats the cat and the mouse.

Detritus

waste or debris of any kind

First-Level Consumer

At the first level, organisms that eat only producers are primary consumers. They're commonly known as herbivores. Primary consumers vary by community, or ecosystem. Some species of grasshoppers and deer feed on forest plants.

Second-level consumer

In a food chain, a second-level consumer is an organism that eats a first-level or primary-level consumer. ... While a second-level consumer is a carnivorous or omnivorous animal, a first-level consumer is an herbivore. What is a second level c

Producer

Producer: is an organism, either a green plant or bacterium, which is part of the first level of a food chain.

Tertiary consumer

a carnivore at the topmost level in a food chain that feeds on other carnivores; an animal that feeds only on secondary consumers.

Food chain

a hierarchical series of organisms each dependent on the next as a source of food.

food web

a system of interlocking and interdependent food chains.

Detritivore

an animal that feeds on dead organic material especially plant detritus

Primary Consumer

an example is a rabbit that eats grass. The next link in the chain is animals that eat herbivores - these are called secondary consumers -- an example is a snake that eat rabbits.

Decomposer

an organism especially a soil bacterium, fungus or invertebrate that decomposes organic material.
