B7 Ecology

5. a component of the soil that plants compete for and is transported in xylem vessels
9. plants are an example of these as they make their own food
11. a fuel cut from bog land, that burns to release carbon dioxide. Digging this material destroys precious habitat
13. random sampling is essential to avid this
14. how water from the land forms clouds
15. non living factors that affect population distribution
17. plants compete for light as it is essential for this process
18. bacteria and fungi are examples of these organisms that decay dead organic material
19. components of the soil that plants compete for, nitrate is an example of this
20. a process that all living organisms do that produces carbon dioxide

1. this process clears vast areas for farm land, rice fields, or to grow crops for biofuel
2. animals compete for water, food, territory and this other factor
3. a stretched tape across a habitat used to sample how species change as we move from one area to an other
4. organisms that live in extreme environments, like high salt or high temperature conditions
6. these squares are used in sampling, and can be placed randomly during the sampling process
7. animals that hunt and kill other animals for food
8. along with carbon dioxide this is a key greenhouse gas.
10. living factors that affect population distribution
12. what farmers put on their crops to ensure they have enough minerals, and this can enter water systems and cause pollution
16. the variety of all the different species of organisms on earth, or within an ecosystem.
