Match the following
a. |
1. Biotic factors |
b. |
2. Decomposers |
c. |
3. Abiotic factor |
- a - 2, b - 1, c - 3
- a - 3, b -1, c - 2
- a -1, b - 2, c - 3
- a - 3, b - 2, c - 1
Hint:
The living organisms in an ecosystem can be divided into three categories: producers, consumers, and decomposers
The correct answer is: a - 3, b -1, c - 2
- Producers are green plants. They make their own food. Consumers are animals and they get their energy from the producers or from organisms that eat producers.
- There are three types of consumers: herbivores are animals that eat plants, carnivores are animals that eat herbivores and sometimes other carnivores, and omnivores are animals that eat plants and other animals.
- The third type of living organism in an ecosystem is the decomposer. Decomposers are plants and animals that break down dead plants and animals into organic materials that go back into the soil, which is where we started.
