• wind, rainforest
• rain, rainforest

• Weather is the temperature in an area and climate is the amount of rainfall in an area
• Weather is the day to day temperature and precipitation and climate is the average temperature and precipitation

6. A plant grower has a greenhouse where she grows plants in the winter. The greenhouse is exposed to direct sunlight and often gets too hot for the plants. She paints the inside of the glass with chalky white paint, and the temperature drops to comfortable levels. Explain why this procedure works.

• The white paint reflects the light and increases the greenhouse effect
• The white paint absorbs the light and increases the greenhouse effect
• The white paint reflects the light and decreases the greenhouse effect
• The white paint absorbs the light and decreases the greenhouse effect

7. A relationship in which one organism is helped and another organism is neither helped or hurt, such as a shark and remora fish is

• mutualism
• competition
• commensalism

8. The relationship between a tick and it’s host is an example of

• commensalism
• succession

9. What is the difference between an organism’s habitat and its niche?

• A habitat is the abiotic factors and a niche is the biotic factors
• A habitat is the biotic factors and a niche is the abiotic factors
• A habitat is where an organism lives and a niche is how it lives in its environment
• A habitat is how an organism lives in its environment and a niche is where an organism lives

10. What is the competitive exclusion principle?

• No two organisms can have the same niche at the same time
• No two organisms can eat the same organism at the same time
• No two organisms can be eaten by the same organism at the same time
• No two species can live in the same ecosystem at the same time
