To give a basic and broad perspective answer this is an example of common organism feeding patterns.
ex: the water's cellular life base and the sun's rays help the, per say, blade of grass be nurtured, that same blade of grass either is eaten by an insect, a herbivore, or dies and withers to help nurture fungi in the forest. The insect who ate that blade of grass is perhaps later eaten by a frog. The frog, who ate the insect that had eaten the grass, is perhaps eaten by a bird of prey. The bird is possibly hunted and becomes our next meal or is killed off and eaten by a cougar. From there the cycle continues on to larger, voracious animals till it finally goes back to that single blade of grass.
the question is unspecific every living thing is considered an organism
An organism that eats other organisms for energy are known as heterotrophs.
A carnivore is an organism that eats other organisms to obtain nutrients and sustain life.
A consumer. Carnivores and herbivores alike.
A niche is an organism's role in a community. What it eats, Where it eats, When it eats, and its job in that environment.

A carnivore is an organism that eats other organisms to obtain nutrients and sustain life.
herbivore
When an organism from a higher trophic level eats one from a lower trophic level, it gains energy and nutrients from the consumed organism. This contributes to the transfer of energy through the food chain and helps regulate population sizes in the ecosystem.
Carnivore if it eats meat. Omnivore if it eats both. If it is a carnivore that eats insects it is engaging in entomophagy.
If an animal on a high trophic level eats other organisms on a lower trophic level effected by DDT, the animals level will be affected.
An organism that eats other oranisms is called a heterotroph.
carnivores
When one organism eats another, it is called predation. The predator (the organism that eats the other) benefits by obtaining nutrients and energy from the prey. The prey may be killed or harmed in the process.
Animals that eat other organisms are called carnivores, or sometimes secondary consumers.
A consumer. Carnivores and herbivores alike.
