Q: Animals, such as the elephant, obtain energy by consuming plants. Which equation best represents the process by which animals convert this energy for cellular use?

$$C_6H_{12}O_6$ + 6O_2 \rightarrow 6CO_2 + 6H_2O + \text{ATP}$$

Question 1

Based on the diagram, which process is primarily responsible for converting solar energy into chemical energy in the ecosystem?

Accepted Answer

Photosynthesis

Question 2

Which of the following best describes the role of animals, such as the elephant in the image, in the cycling of chemical nutrients?

Accepted Answer

They consume plant material and contribute to nutrient cycling through waste and decomposition.

Question 3

What is the main gas released by plants during photosynthesis, as shown in the diagram?

Accepted Answer

Oxygen ($$O_2)$$

Question 4

Which of the following equations correctly represents the overall process of photosynthesis occurring in the leaves?

Accepted Answer

$$6CO_2 + 6H_2O \rightarrow C_6H_{12}O_6$ + 6O_2$$

Question 5

If the leaves of the tree were removed, which process in the diagram would be directly disrupted first?

Accepted Answer

Absorption of light energy and gas exchange

Question 6

Which of the following best explains why the cycling of chemical nutrients is essential for ecosystem stability, as depicted in the diagram?

Accepted Answer

It allows for the reuse of essential elements by plants and animals.

Question 7

Which process in the diagram is most directly responsible for returning minerals to the soil?

Accepted Answer

Decomposition

Question 8

Animals, such as the elephant, obtain energy by consuming plants. Which equation best represents the process by which animals convert this energy for cellular use?

Accepted Answer

$$C_6H_{12}O_6$ + 6O_2 ightarrow 6CO_2 + 6H_2O + 	ext{ATP}$$

Question 9

Which of the following statements best describes the relationship between photosynthesis and cellular respiration in the ecosystem shown?

Accepted Answer

Photosynthesis produces oxygen and glucose, which are used in cellular respiration by animals.

Question 10

If decomposers were removed from the ecosystem depicted, what would be the most immediate consequence?

Accepted Answer

Nutrients would accumulate in dead organic matter and not return to the soil.
