According to the Embryological studies, the most ancient chordates were closely related to the ancestors of the echinoderms. Echinoderms are members of the group Phylum Echinodermata of marine animals. Some known echinoderms are starfish, and sea cucumbers.
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.
The formation of new viruses.
