Question

Photosynthesis stops due to the atmosphere filled with dust after a meteor strike on Earth. Why would the dust cloud stop photosynthesis?

a
Water is in short supply, and it is a product of the process
b
Chlorophyll breaks down immediately, halting the process
c
Need sunlight to drive process
d
Need an atmospheric swiffer to get it going

Answer 1

c

Need sunlight to drive process

Answer 2

The correct answer is c. Photosynthesis requires sunlight to drive the process. During photosynthesis, plants use energy from sunlight to convert carbon dioxide and water into glucose and oxygen. Chlorophyll, the pigment responsible for capturing sunlight, is crucial for this process. If the atmosphere is filled with dust after a meteor strike, the dust particles can block or scatter sunlight, thereby reducing the amount of light available for photosynthesis. This can inhibit the process and hinder the plants' ability to produce glucose and oxygen.
