Plz..It is not a long one! What is the relationship between each of the following:
producers, consumers, and decomposers in ecosystems?

:D

Producer is an organism that produces it's own food e.g. photosynthesis in plants. Also known as the base of the food-chain.

Consumer is an organism that consumes (eats) either a producer or another consumer e.g. animals will solely eat plants (herbivore) , sole animals (carnivore), or a combination of both (omnivore).

Decomposers are organisms that 'eat' and break up dying/decaying material e.g. earthworms and fungi.

producers create their own food, consumers eat the producers, and decomposers eat consumers after they die and provide fuel for new producers

Explanation:this is a pretty basic way of stating it but if you want more complicated just ask I can help

the electromagnetic energy from the sun arrives in the form of visible and invisible light.

the fossil record provides evidence of a common ancestor to many species.
