Here are the correct answers for your quiz, with a quick explanation for each one to help you understand why they are right.
1. In every ecosystem \_\_\_\_\_\_ interact.
*
Reasoning: An ecosystem isn't just about animals or plants alone. It includes all the living things (biotic factors) like plants and animals, and all the nonliving things (abiotic factors) like water, sunlight, and soil. They all affect each other.
*
Correct Choice: C (all living and nonliving things)
2. In which type of ecosystem is the ground beneath the surface frozen all year?
*
Reasoning: Deserts are hot or dry, wetlands are watery, and rainforests are warm and rainy. The tundra is a very cold biome found near the poles where the soil stays frozen (permafrost).
*
Correct Choice: C (tundra)
3. In which type of ecosystem do cacti grow?
*
Reasoning: Cacti are special plants that store water because they live in places with very little rain. This describes the desert ecosystem.

5. Which of the following is a producer?
