How do energy and nutrients flow through ecosysytem?



The organisms in an ecosystem consist of produces , consumers and decomposers . energy is passed from the producers to consumers to decomposes.

Produces
Produces converts the energy from the sun to chemical energy and stored as food during photosynthesis thus they are either directly or indirectly affect other organisms as they provide energy and oxygen.
Consumers
they feed on other organisms thus all animals are consumer. Herbivores are primary consumers while carnivores are secondary consumers and carnivores that feed on carnivores are tertiary consumers.

Decomposes
They achieve their energy by breaking down dead faeces and excretory products
