Ecology is the study of how living things interact with each other and their environment.

Ecosystems include all living and nonliving things in an area.

Producers like plants make their own food.

Consumers eat other organisms for energy.

Decomposers break down dead organisms and recycle nutrients.

Food chains show how energy flows through an ecosystem.

Biodiversity means the variety of life in an ecosystem.

Habitats provide food, shelter, and space for organisms.

Humans impact ecosystems through pollution and deforestation.

Protecting ecosystems helps maintain life on Earth.
