Tropical Rainforest food web and chain

The tropical rainforest food web is all about who eats who in the rain forest. The tropical food web describes the chain of events every organism goes through to obtain nutrition, or energy, in order to survive in the rain forest. A food web is a network of food chains.

The tropical rainforest food chain lies in the very critical concept of interdependence. Each organism in the food web depends upon all other organisms in the chain for basic survival. For example, if an insect becomes extinct, plants that it consumes will proliferate and equilibrium in the rainforest will be disturbed. In addition, members of the food web that rank above the insect in question will be affected because it will no longer be available for consumption. This disruption leads to further extinction of species and ultimately the entire food web is drastically changed if not completely obliterated.

Key Concepts for the Tropical Rainforest Food Web/chain

Everything about the tropical rainforest is about the flow of energy and the cycling of matter in the ecosystem.

  • All energy comes from the sun (solar system).
  • Plants capture some of this energy by the process of photosynthesis to enable them make food.
  • Plant-eating animals obtain this energy from plants and meat-eating animals, in turn, take energy from them.
  • Death and decay recycles matter and energy to help begin the process anew.
  • All living things need a "home"--a place that provides shelter, food, air, and water.
  • Living things need one another to survive. the connections are different and comprise the "Web of Life." Some relationships involve eating or being eaten, but many other "cooperative" relationships exist--e.g. providing a place to grow, helping pollinate flowers or scatter seeds.
  • Damaging the strands in the Web can have unforeseen and far-reaching consequences.

There are some things we need to know about the Tropical rainforest food web.

  • Each level in the tropical rainforest food web or chain is dependent on the adjoining levels.
  • In the tropical rainforest food chain, autotrophs make their food from sun.
  • These primary producers in the rain forest are eaten by herbivores. herbivores are known as plant eating organisms that are eaten by carnivores and omnivores.
  • The secondary consumers in the tropical rainforest may be eaten by tertiary consumers, who are carnivores.
  • When any organism dies, in the rain forest tiny microbes (detrivores) take over and decay occurs .
  • The cycle in the food chain or food web continues
