Trophic Levels

A trophic level is the hierarchal position that an organism or group or organisms occupies in an ecosystem. 3 levels can be mainly found in an ecosystem:

• Producers: An organism that obtains organic food molecules without eating other organisms but by using energy from the sun or inorganic molecules to make organic molecules.
• Consumers: An organism that obtains its nutrition by eating other organisms. Herbivores and Carnivores. The role of consumers in an ecosystem is to transfer energy from one trophic level to the next. In this trophic level, we can find several sublevels in which species can be classified into: primary, secondary tertiary and quaternary consumers.
• Decomposers: An organism that obtains energy by breaking down dead organic matter into more simple substances. Alco called saprobes.
