Answer :
The long, bulky brown algal seaweeds are called kelps. These kelps are multicellular, microscopic algae that may be found in the shallow seas. In kelps, there is the following connection between carbon dioxide and oxygen:
During photosynthesis, oxygen and carbon dioxide are needed.
Algae are eukaryotic, watery, photosynthesis-based creatures. Algae are living things with one cell or many cells, like kelp.
Multicellular algae like kelps use photosynthesis to create food and release oxygen. The act of eating carbon dioxide and water in the presence of sunshine in order to produce oxygen and create sugar for energy is known as photosynthesis.
As a result, the kelps employ oxygen and carbon dioxide to carry out photosynthesis.
