Question

unit 2 exam 2023 - 20
as a result of photosynthesis
our atmosphere is now rich in oxygen gas
animals can get energy directly from the sun
plants convert chlorophyll into protein
abundant quantities of carbon dioxide are available to fuel the calvin cycle

Explanation:

Photosynthesis is a process by which plants use sunlight, carbon - dioxide, and water to produce glucose and oxygen. Oxygen is released into the atmosphere as a by - product, making our atmosphere rich in oxygen gas. Animals cannot get energy directly from the sun as they are heterotrophs. Plants do not convert chlorophyll into protein. Abundant carbon dioxide is taken in, not made available as a result of photosynthesis for the Calvin cycle.

Answer:

our atmosphere is now rich in oxygen gas
