A: a group of organisms that can produce fertile offspring
B: a group of organisms of the same species that live in the same areas
C: a community of organisms that live in the same area
D: a large area that flora and fauna live in to make an ecosystem

3. 2. Which of the following best describes a biome?
A: a natural community that is unaffected by human activity
B: the quantity of water within an area for a specific time period
C: a group of ecosystems with similar climates and organisms
D: a community that is able to survive prolonged high temperatures

4. 3. Otters have adaptive traits that allow them to survive by eating shellfish (shrimp) and crustaceans (crabs). If changes in biotic factors of the ecosystem result in reduced number of shellfish and crustaceans, the otters will most likely..
A: experience a population decline
B: adapt to a different ecosystem
C: change the genetic makeup of their bodies
D: increase reproduction rates

5. 4. In some areas of Texas, rainfall quickly soaks through layers of porous rock and is stored naturally underground. The water is then pumped into homes for people to use. What would have the greatest impact on the amount of water available for people in this area?

B: long periods without rainfall
C: below freezing temperatures for many consecutive days
D: flooding of a local creek

11. 10. How is secondary succession different from primary succession?
A: secondary succession occurs after a disturbance in an area which the soil remained intact
B: secondary succession occurs after a disturbance in an area that was previously uninhabited
C: Secondary succession occurs over a longer period of time than primary succession
