Ecosystems Skill Builder
| # | Answer |
|---|---|
| 1 | An ecosystem is a place where living things and nonliving things interact with each other. |
| 2 | Example: a squirrel and sunlight. |
| 3 | A tree. |
| 4 | They need sunlight, water, air, and nutrients. |
| 5 | Consumers depend on producers for food directly or indirectly. |
| 6 | Example: grass -> grasshopper -> frog. |
| 7 | Decomposers break down dead plants and animals and return nutrients to the soil. |
| 8 | A predator hunts another animal for food, and prey is the animal that is hunted. |
| 9 | Animals that depend on algae for food would have less energy, and the food chain would be affected. |
| 10 | Example: Water helps plants grow and gives animals something to drink. |
| 11 | Biodiversity means the variety of different living things in an area. |
| 12 | Different plants provide food, shelter, and habitats for many organisms. |
| 13 | A drought can reduce water for plants and animals, causing some to die or move away. |
| 14 | It can slow water flow, create a pond, and change habitats for plants and animals. |
| 15 | Energy moves from the sun to producers and then to consumers as they eat one another. |
| 16 | The animals it used to eat may increase in number and affect other parts of the ecosystem. |
| 17 | Because living things depend on each other for food, shelter, and survival. |
| 18 | A habitat is where one organism lives, while an ecosystem includes the living and nonliving things in an area and how they interact. |
| 19 | Birds may have less food because many birds eat insects. |
| 20 | Animals may lose food and shelter, and many plants and animals may move away or die because the habitat is gone. |
