Questions

1) Define Ecology.

2) What is the difference between biotic and abiotic factors? Give some examples of both

3) Give some examples of ecosystems. How often can they change and why?

4) How do biotic factors interact with other biotic factors and the abiotic?

5) What are some of the major biomes in the world?

6) Draw an illustration of the levels of organization from a cell all the way up to a biome.

12.1 Questions 1-5

Also complete your mini poster for the zebra mussels.

Must include information about the zebra mussel and how to prevent their movement from one area to another.


Research Questions

1. Draw a diagram of an ecosystem near where you live . Label the factors “biotic” or “abiotic.”

2. Give two examples of how plants and animals affect their environment

3. Describe how temperature, light, and soil affect an ecosystem

4. Think of a forest ecosystem. Now imagine that a large amounts of dust and ash into the air, blocking out sunlight. How might the forest ecosystem be affected if the sunlight is blocked out for a day? For a year? (ANSWER MUST BE A PARAGRAPH)
