Food network #2
An ecosystem groups together living beings (plant and animal) and the environment in which they live and interact.
A food network (or trophic network) is the joining of many food chains in the same ecosystem. In this network, a living being consumes another to insure its survival.
For this reason, we can characterize a trophic level by the transfer of energy (material) of a living being to another according to a particular hierarchy. We can also distinguish:
- The producers (plants) capable of producing their own energy (material) principally by photosynthetic processes.
- The consumers (animals) eat other elements in order to get energy. Herbivores, carnivores and top carnivores are all part of the consumer category.
- The decomposers, not represented in this animation, complete the life cycle by degrading the organic materials of each category below (bacteria, fungus, insects).
