Document Summary

Heterotrophs are organisms who eat already made organic material and have adapted towa consume. Long gut for digesting cellulose and other low quality plant matter. Adaptations to consume and capture prey via sting cells, sharp teeth claws. Live on and obtain nutrition from another organism. Early fossils were soft bodied until predators were introduced and harder bodies started to a. Species approach the topic of predation by either. Specialize in a certain type for increased efficiency d towards the kind of diet they d to appear. Specialize in a certain type for increased efficiency. Generalize for balanced diet and reduced toxicity or balanced diet. Essentially want high value prey at lowest cost possible. Optimal foraging: the process by which organisms increase the difference between cost an prey. Increase the energy gain per unit/time and decrease the energy lost while foraging.
