What is an example of how organisms respond to long term changes in the environment?

• Animals tend to eat a lot more.

• Animals will hibernate.

• Animals must be able to adapt to a new environment.

• Animals will go extinct or die due to the short term change.

Field mice eat corn. In this particular ecosystem, there are no predators to the field mice. Which would most likely happen if the field mouse population grew?

• There would be more corn to feed the field mice.
• There would be less corn due to the mice eating it.
• The habitat would get overpopulated because the mice would eat too much.

• The mice will adapt to eat less corn so there will be more for all of the extra mice.

If an invasive plant is brought to a forest and starts growing prolifically, then:

• the sunlight will be more abundant.

• native plant growth decreases.
• nutrients in the soil will increase.

• The new plant and the native plants will most likely coexist.

Copper compounds are used to control the growth of algae and other aquatic plants. Copper interferes with photosynthesis in these organisms. What would be the most likely result of an accidental spill of these compounds in an aquatic environment?

• Fish would grow larger than usual
• Zooplankton would increase
• Plants would increase in size and decrease in number
• The plant populations would be reduced

A description of the Eastern cottontail rabbit species is below. The environment that supports an Eastern cottontail population is changed due to urban development. Much of the land is cleared and covered in concrete. How is this urban development most likely to affect the population of rabbits?

• The number of gray rabbits will increase because the brown rabbits will turn gray.

• The number of brown rabbits will increase because the gray rabbits will turn brown.

• The number of gray rabbits will increase because predators will see brown rabbits more easily.

• The number of brown rabbits will increase because predators will see gray rabbits more easily.
