Biotic vs. Abiotic Components
Learning Objective
I can differentiate between biotic and abiotic components in an ecosystem.
Key Concepts
A population includes all the members of one species that live in the same area and can reproduce.
An ecosystem is made up of living, biotic, and non-living, abiotic, things in an area.
Producers, like plants, make their own food, while consumers depend on other organisms for food; decomposers break down dead organisms.
