1. Identify three different types of consumers. Name an example of each type.
2. What are photoautotrophs? Give an example of one.
3. What can you infer about an ecosystem that depends on
chemoautotrophs for food?
4. What is the role of decomposers?
5. What do scavengers do? Give an example of a scavenger.

1.a. Omnivores, Carnivores, and Herbivores.

1.b. Foxes, Tigers, and Deer.

2.a. A photosynthetic organism (such as a green plant or a cyanobacterium) that utilizes energy from light to synthesize organic molecules Green plants that convert carbon dioxide into carbohydrates in the presence of sunlight are called photoautotrophs.

2.b. Maize Plant.

3. Chemoautotrophs made their food by themselves using the energy from the sun. This means that an ecosystem that depends on chemoautotrophs for food is dependent on sunlight for food and survival because chemoautotrophic organisms are the primary producers in that ecosystem.

4. Decomposers are organisms that break down dead plants or animals into the substances that plants need for growth.

5.a. They keep an ecosystem free of the bodies of dead animals, or carrion. Scavengers break down this organic material and recycle it into the ecosystem as nutrients.

5.b. Turkey Vulture.
