Producers

Explanation:

Organisms who make (or produce) their own food are called producers, plants are capable of self-feed through the process of photosynthesis, therefore, they are producers. These producers are the first energy source for primary consumers and the star of the living food chain. Consumers are animals that consume other organisms, they are divided into three categories: primary (herbivores), secondary (carnivores and omnivores), tertiary consumers (they consume energy from all other levels). The final link in this food chain is the decomposers, also known as detritivores, they eat decaying or dead matter including dead plants or animals, returning vital nutrients to the soil.

Biomagnifiers are organisms that tolerate increasing concentration of a substance at successively higher levels in a food chain. A bioaccummulator is an organism that suffers a net accumulation of a contaminant from all sources including water, air, and diet. Biomagnifiers and bioaccumulator can be from plants to animals all across the food chain.
