Middle School Life Science

Middle School Life Science explores the fundamental concepts of biology, ecology, and the interactions of living organisms with their environment.

Basic Concepts

Ecosystems and Interactions

Exploring Ecosystems

An ecosystem is a community of living things (plants, animals, and microbes) interacting with each other and with their nonliving environment (like air, water, and soil).

Relationships in Nature

Organisms in an ecosystem rely on each other. Food chains and food webs show who eats whom, and how energy flows through the system.

Balance is Key

If one part of an ecosystem changes (like if a species dies out), it can affect all the other living things in that system.

Everyday Example

Healthy ecosystems provide us with clean water, oxygen, and food.

Examples

  • A pond with frogs, fish, plants, and insects all interacting.

  • A forest where trees, animals, and fungi depend on each other for survival.

In a Nutshell

Ecosystems are communities of living and nonliving things that interact in specific environments.
