Question 23

23.

Predict how a decrease in the number of predators- due to hunting- might affect the cycling of carbon in the Serenegti. Use the diagram in the previous question to support your answer.

Question 2

2.

When an organism dies, nutrients are returned to the environment.

True

False

Question 4

4.

List two functions of nitrogen in plants.

Question 5

5.

List two functions of phosphorus in plants.

Question 6

6.

Which of the following statements best describes where plants get these nutrients (hint: Look at the cards)

A. carbon from the soil, nitrogen and phosphorus from the air

B. carbon, nitrogen, and phosphorus from the soil

C. carbon, nitrogen, and phosphours from the air

D. carbon from the air, nitrogen and phosphorus from the soil

Question 9

9.

The process cards showed ways in which nutrients can be taken up by plants. Choose a process card that describes plants getting nutrients from wildebeest. Does your cards differ in the amount of carbon, nitrogen, and phosphorus they make available to a plant? If so how?

Question 10

10.

The soil microbe cards represent microorganisms such as bacteria. Based on the activity summarize how microbes help cycle nutrients in the Serengeti.

Question 11

11.

The detritivore cards represent organisms that eat decomposing matter and feces. Based on the activity, summarize how detritivores help cycle nutrients in the Serengeti?

Question 12

12.

One process that moves carbon between organisms and the environment is cellular respiration. During cellular respiration, organisms break down energy and produce carbon dioxide gas (CO2). In the card activity, which two process cards directly represent cellular respiration?
Choose 2

A. Animals eat organic compounds for energy and release CO2

B. Animals die and soft tissue decomposes

C. Denitrifying bacteria convert nitrate into N2 gas that escapes to the atmosphere

D. Plants use organic carbon for energy and release CO2

E. Inorganic minerals teach into groundwater

F. Animals graze and defecate
