Compare the process of carbon fixation in C3 plants to that of C4 plants.
Gre4nikov [31]

Carbon fixation is the process in which plants remove the carbon from atmospheric carbon dioxide and turn it into organic molecules like carbohydrates.

Because different type of plants are located in regions with different conditions they are different types of carbon fixation.  Plants that live in arid regions need to conserve water, while plants that live in more moist conditions will not need to conserve water.

The carbon fixation in C3 plants is one-step process. An oxidation reaction occurs because of the enzyme RuBisCo.  During the oxidation some of the energy used in photosynthesis is lost in a process known as photorespiration.

Explanation:

The Earth axis of rotation is tilted to 23.5 degrees which is relatively to the orbital plane, this lead to differences in seasons of the places on Earth at a particular time. The angles varies overtime but moon gravitational pull prevent it from shifting more than a degree. There is different in seasons in the northern and southern hemisphere because at a time one part of it exposed to the Ray's of sunlight than the other which lead how the Earth's revolve round it's axis.
