Answer:
Photosynthesis
Step-by-step explanation:
Of the given processes, the process that consumes carbon is D. Photosynthesis.
Photosynthesis is the process by which plants, algae, and some bacteria convert carbon dioxide and water into glucose (a type of sugar) and oxygen. During photosynthesis, carbon dioxide is taken in from the atmosphere and used to build the glucose molecule, which is stored in the plant or used as energy. This means that photosynthesis removes carbon dioxide from the atmosphere and fixes it in the form of organic molecules in the plant.
In contrast, the other processes listed either release carbon dioxide into the atmosphere or do not involve carbon at all:
A. Decomposition - the process of breaking down organic matter into simpler components. Decomposition can release carbon dioxide into the atmosphere as a byproduct.
B. Combustion - the process of burning a substance, usually for energy. Combustion releases carbon dioxide into the atmosphere as a byproduct.
C. Weathering - the process of breaking down rocks and minerals into smaller pieces. Weathering does not directly involve carbon.
