Practical Applications

Investigating Ecosystems

Exploring Life Where You Live

Ecosystems are communities of living and nonliving things that interact in a specific area. By studying local ecosystems, we learn how plants, animals, water, and soil work together.

How To Investigate

  • Observe plants and animals in a nearby park or backyard.
  • Record the types of organisms and what they do.
  • Notice how weather, water, and soil affect living things.

Why It’s Important

Understanding ecosystems helps us protect endangered species and keep our environment healthy.

Examples

  • Keeping a nature journal about insects, birds, and plants in your neighborhood.

  • Testing pond water to see what organisms live there.
