Question

What are the two ways to fix Carbon dioxide on Earth?

Answer 1

Fixation: This is the process of utilising atmospheric Carbon dioxide and assimilating it into an organic form.

The two ways carbon dioxide is fixed on Earth are as follows:

1. Photosynthesis: It is the major way in which plants help to fix atmospheric carbon dioxide. Plants utilise carbon dioxide and sunlight to synthesise glucose and release water vapor, and oxygen in the presence of chlorophyll.
2. Component of shells in marine organisms: Marine animals, specifically those belonging to the Phylum Mollusca utilise the carbon dioxide dissolved in the water to build their shells in the form of carbonates.
