Habitats

Grade 4 · Science · Free lesson

Hi there! I am Studyfin, your science buddy. Today, we will explore how living things and nonliving things work together in their homes!

A habitat is a home for plants and animals. Some habitats are small, like a simple bowl or a glass tank. An aquarium is a water home, while a terrarium is a land home.

Living things depend on nonliving things to survive. In an aquarium, fish need nonliving water to swim and nonliving oxygen to breathe. This is called an interaction.

Fish depend on nonliving water and oxygen!

Living things also depend on each other for food. We can show this connection using a food chain. It shows how energy flows from the sun to plants, and then to animals.

✏️ Worked example

Let us analyze a terrarium with soil, clover plants, and snails. How do these components interact, and how do they depend on each other?

  1. First, identify the nonliving parts. The soil, air, and water are nonliving components.
  2. Next, identify the living parts. The clover plants and snails are the living components.
  3. Then, look for interactions. The clover plants grow in the nonliving soil and drink the water.
  4. Now, look for dependencies. The snails need the clover plants for food and shelter.
  5. Finally, write down the food chain. The clover uses sunlight to make food. The snail eats the clover.
