Ecosystems Review Worksheet
| # | Answer |
|---|---|
| 1 | An ecosystem is a place where living and nonliving things interact with each other. |
| 2 | Examples include trees, birds, rabbits, insects, or mushrooms. |
| 3 | Examples include sunlight, water, air, rocks, and soil. |
| 4 | A habitat is the natural place where a living thing lives and gets what it needs. |
| 5 | Plants need sunlight to make their own food. |
| 6 | Herbivores eat plants. |
| 7 | A plant usually comes first because it makes food using sunlight. |
| 8 | Producers make their own food, and consumers must eat other living things for energy. |
| 9 | Example: grass → rabbit → fox. |
| 10 | Animals may have trouble surviving because they need clean water to live and stay healthy. |
| 11 | Decomposers break down dead plants and animals and return nutrients to the soil. |
| 12 | They show how energy moves from one living thing to another and how organisms depend on each other. |
| 13 | The birds may have less food, so their population could decrease. |
| 14 | A drought can reduce water for plants, causing fewer plants to grow and affecting animals that depend on them. |
| 15 | Example: In a pond, fish depend on water to live, and the water provides a place for them to swim and find food. |
