In ecology, energy flow refers to the energy going from one organism to another in an ecosystem.
Trophic levels refer to the position that an organism has in a food web or food web.
The first level is the producers, which are autotrophic organisms that can produce energy from inorganic sources through processes such as photosynthesis. Here we can find plants, algae, and bacteria.
The next level is primary consumers, which are organisms that feed on the producers. This includes herbivores.
Next, there are secondary and tertiary consumers, which are carnivores that eat herbivores, and carnivores that eat carnivores.
There is also an extra trophic level of decomposers, which feed on the remains of other living beings and left behind nutrients that can be used by producers.
Just a fraction of the energy in each level passes to the next, which means there are fewer organisms going from one level to the next.
