In a food web there is a hierarchy, if any one of the parts of a food web is changed it can effect the parts above that may consume it, or the parts below that it may consume. Since the food web relies on balance and a hierarchy, if something changes it could disrupt the balance and flow of energy in the food web.

Explanation:
Chlorophyll pigments absorb most of the light in the blue and red regions. Blue-violet region marks the peak absorption by chlorophyll a while chlorophyll b shows peak absorption in red blue light. Green colored light is not absorbed by chlorophyll a and b. Light absorption by chlorophyll is essential for the light-dependent phase of photosynthesis. Therefore the plant A grown under blue light will show maximum growth and plant B kept under green light would show minimum growth.
Lecithin is (organic chemistry) the principal phospholipid in animals; it is particularly abundant in egg yolks, and is extracted commercially from soy. It is also a major constituent of cell membranes, and is commonly used as a food additive (as an emulsifier). While cephalin is (biochemistry) a phospholipid found particularly in the cells of nervous tissue; it is also the primary phospholipid in bacteria.
Thanks to the presence of a nucleolus, cells can generate and interact with proteins that help them generate more cells and perform other complex tasks.
