Question 4

4.

If the population of rabbits is reduced by disease, which change will most likely occur in the food web below?

The grasses will decrease.

The mountain lion population will increase.

Question 5

5.

The graph below shows how the population of gopher turtles and snowy egrets changed over the last 60 years in a particular wetland. What can you infer based on the information presented in the graph?

The water in the wetland area contains chemicals that affect the gopher turtle population.

Use the diagram below to answer question 8.

There are three species of birds on an island. Bird A has a heavy bill for eating big seeds. Bird B has a sharply pointed bill for eating insects.

Refer to the tables provided. Which plants depend on and may compete for sandy soil in zone 9?

Loblolly Pine and Black Hickory.

Live Oak and Post Oak.

Question 8

8.

The Louisiana fishing industry has been suffering due to the recent pandemic. More and more fisherman have been fishing the coastal waters causing the coastline to be overfished. Which of these activities will most likely increase the fish population?

Introducing an invasive species of fish that reproduces at a rapid rate, but kills the current the fish population.

Limit the fishing activity, allowing for the current fish population to grow.

Keep the fishing activity at the same rate and allow the fish to reproduce at its own pace.

Encourage fisherman to only fish for large predatory fish such as sharks.

Question 9

9.

Scientists are studying the effects of climate change on th Baltic Sea. Some scientists predict that if current trends continue, the Baltic Sea will become less salty, and it will contain less dissolved oxygen. As a result of these changes, the Baltic Sea will have less biodiversity. The location of the Baltic Sea is shown on the map below.

Which statement best explains why biodiversity in the Baltic Sea could descrease if these changes occur?

Animals adapted for living in warm water will eat all the plants and animals adapted for living in cool water.

Question 10

10.

Copper compounds are used in large amounts to control the growth of algae and other aquatic plants. Copper interferes with photosynthesis in these organisms.

The fish would grow larger than usual.

The zooplankton population would increase.

The plant populations would be reduced. 

Predator/prey

Parasite/host

Minerals

The deer population will decrease.

The hawk population will increase.

The gopher turtle is best suited for life in the wetland today.

The snowy egret has adapted features that help it to survive and reproduce in this particular wetland today.

Bird A

Bird B

Bird A and Bird B

Post Oak and Chinese Elm.

Black Hickory and Sweetgum.

Plants and animals adapted for living in saltier conditions will not be able to survive and reproduce.

Plants and animals adpated for living in saltwater will grow more slowly in water that has less salt.

Fewer types of plants and animals are found in warm water than in cool water.

The plants would increase in size but decrease in number.
