  4. What is a Population? • A population is one species living in a specific area. • For example, all foxes living in an area form a population. • Another example, all dandelions growing in an area form another population.

  5. What is a Community? • A community is formed from all living populations found in an area. • All the foxes, dandelions, grasshoppers, snakes, hawks, deer, and skunks living in one area each form their individual populations, but together make up a community.

  6. What is a Ecosystem? • An ecosystem is formed by the interactions between all living and non-living things • How do living and non-living things interact in an environment?
