2.10 Biotic and Abiotic Factors Class Notes

An ecosystem is all the living and non-living things in an area and their interaction with each other.

Biotic Factors Biotic = living (BIO = life) Biotic factors are all of the living things in an ecosystem.

Let’s Practice… 1. What is a biotic factor? 2. What are two biotic factors in this picture?

Abiotic Factors Abiotic = nonliving Abiotic factors are all of the nonliving things in an ecosystem.

Let’s Practice… 1. What is an abiotic factor? 2. Name 2 abiotic factors in this picture.

Let’s Practice… What is one biotic and one abiotic factor in this picture?
