What might happen to the organisms in the food web below if the number of phytoplankton and vegetation drastically decreased? A food web titled Chesapeake Bay Waterbird Food Web. It shows a very complex food web with many different food chains of various species displayed in 5 categories: Producers, Herbivores, Primary consumers, Secondary consumers, Tertiary consumers. The small fish and wading birds would be affected. Only the small fish would be affected. The small fish, bivalves, and invertebrates would be affected. The entire food web would be affected.

The entire food web would be affected.

Explanation:

The trophic web is the process of energy transference through a series of organisms, in which every organism feeds on the preceding one and becomes food for the next one. The first link is an autotroph organism or producer, such as a vegetable, that can synthesize organic matter from inorganic matter. These organisms are the base of the trophic chain, so whenever their population decreases, they inevitably affect the whole food web.

This is because when one of the links disappears, it affects the superior links as they will not have their food source. So if the primary producers population decreases, Herbivores will not have enough source of food, to feed on. Their growth rate will be limited by this lack. They might be so affected that their population will probably decline. This will affect primary consumers, and so on. The whole chain will be affected because the base of the trophic web is missing.
