1. What two things govern the biome of a certain area?
2. Temperature and moisture influence….
3. Net primary productivity can be calculated by….
4. What biome has the highest net primary productivity?
5. How can net primary production be estimated?
List the biomes that are described below:
6. Dominated by deciduous trees that become leafless in the winter and in the spring and summer grow new leaves. Evergreens are also present.
7. Plants have broad leaves and are evergreen. They vary in size and growth. The diverse heights of trees provide many different habitats for animals.
8. Dominated by conifers. Aboveground biomass is high because the species live for a long period of time. Low species diversity.
9. Ground covered by low plants or lichens, but no trees. Animal diversity is low, though insect abundance can be high.

Growth is slow through the year, or occurs during rainfall episodes. 11. Grasses dominate in these dry conditions, so trees can’t grow or are burned down in fires. Plant life is dense above and belowground.
12. What are the biomes called where humans directly affect the distribution of terrestrial ecosystems by physically changing the landscape?
13. What four tools can we use to predict how global warming will affect different ecosystems?
14. List a factor that affects the distribution and abundance of organisms that live in aquatic biomes?
15. What is a synonym of turbidity?
List the water depth zones based on the descriptions below:
16. Regions of the littoral, limnetic, and benthic zones that receive sunlight.
17. Offshore, comprises water that receives enough light to support photosynthesis.
18. Made up of the bottom or substrate.
19. Portions that don’t receive sunlight.
20. What aquatic biome are the zones listed above found in?
