So, how does energy move through and ecosystem? As mentioned before, the producers, consumers, and decomposers are one of the biggest parts of energy flow. In this ecosystem, the grass takes in the energy from the sun through photosynthesis, and the energy is used by a consumer, and the decomposers break it down during cellular respiration and make the energy reusable for other parts of the ecosystem.

Biomass is the total amount of mass in organisms in an ecosystem. It can affect the way any organism lives in an ecosystem. In the ecological pyramid to the right, it shows the amount of biomass in each part, and it can show how it affects the energy in the ecosystem.

The food chains and webs in an ecosystem are a very strong factor in survival of organisms. If one part is affected, it starts to have a gradual affect on the other organisms connected in the food chain.

The whole cycle of energy starts with the producer, most likely being plants, which are eukaryotes. Next is the consumer, the organism that gets its energy from the plant. It does not get the full amount of energy that was first taken in by the plant. Lastly are the decomposers, which are bacteria, fungi, etc. They are the part in cellular respiration. They break down the energy received by heat and make it usable for the organism, and the energy not used eventually comes back out as egested waste or detritus. Once these nutrients are returned to the ecosystem, it is then reusable to other organisms.
