Describe a food chain and the flow of energy in it
Answers
Explanation:
Food chains show the levels of consumption between organisms. Each level of consumption is considered to be a different trophic level, and the trophic relationships between species in a community become food webs. When predators and parasites (secondary and higher-level consumers) prey on herbivores or other consumers, they continue the biomass conversion process between trophic levels. However, only a small percentage of the biomass at one trophic level is converted into biomass at the next trophic level. This is because a large amount of energy is expended in maintaining the organisms at each level (as much as 90% of the consumed energy). Additionally, a large amount of biomass at each level is never consumed- this biomass is broken down by detritivores and decomposers.
