Question

describing photosynthesis
analyze the description of photosynthesis. the numbers represent the sentences in the passage and will help you answer the question
(1) photosynthesis is the process by which plants convert chemical energy to light energy (2) this process is important in many ways. (3) photosynthesis is the primary source of oxygen of humans, animals, and plants that contain chlorophyll (4) photosynthesis allows the flow of energy from animals to plants.
which corrections should be made to describe photosynthesis accurately? check all that apply
(1) light energy and chemical energy should be switched.
(1) chemical energy should be changed to mechanical energy
(3) plants that contain chlorophyll should not be included
(3) oxygen should be changed to carbon dioxide
(4) animals and plants should be switched

Explanation:

• For (1): Photosynthesis converts light energy (from sunlight) to chemical energy (in glucose). So light energy and chemical energy in (1) should be switched.
• For (3): Photosynthesis produces oxygen (as a by - product), not carbon dioxide. Carbon dioxide is taken in during photosynthesis.
• For (4): Energy flows from the sun to plants (via photosynthesis) and then to animals (when they eat plants or other animals that ate plants). So animals and plants in (4) should be switched.

Answer:

(1) Light energy and chemical energy should be switched; (3) Oxygen should be changed to carbon dioxide; (4) Animals and plants should be switched.
