A living thing that gets its food by eating other organisms because it can't make its own.  A consumer.

• autotroph

• heterotroph

• interdependence

• energy pyramid

A type of exchange between organisms where they work together to achieve a common goal or benefit. This can involve activities such as cooperation in hunting, foraging, or defense against predators. These exchanges can also occur between members of the same species (intraspecific) or different species (interspecific).

• antagonistic interaction

• trophic levels

An association between organisms where one organism benefits at the expense of the other. These interactions involve interactions such as predation, herbivory, and parasitism.
