Question

These entities sequester most carbon from the atmosphere
A. Plants
B. Archaea
C. Bacteria
D. Insects

Answer 1

Hint:
Before we proceed with the answer, it is important to know about plant sequestering.
Plants sequester substances in the form of organic molecules. These molecules can be harmful to us if they're released into the environment, so plants use them to their advantage. By sequestering these substances, plants protect us and the environment from adverse effects.

Complete step by step answer:
Plants sequester most carbon from the atmosphere through photosynthesis, which converts solar energy into food for the plant. This process helps to mitigate climate change by removing carbon dioxide from the air and storing it in organic material such as leaves or wood.
Plants sequester carbon in three ways:
Through photosynthesis, which transforms sunlight into food; their root system pulls up large quantities of soil and helps to stabilize the earth's surface.
Through the cellulose they produce, which acts as a storage mechanism.
Together, these actions result in plants removing around 26–28% of all CO₂ from the atmosphere. This is more than any other living thing on Earth.

Option ‘A’ is correct

Note:
Plants are one of the most important entities when it comes to sequestering carbon from the atmosphere. They convert sunlight into energy that they use to create oxygen and store carbohydrates as biomass. Over time, this process of photosynthesis results in plant growth, which ultimately absorbs more CO₂ than is released back into the atmosphere.
