A trophic level is the group of organisms within an ecosystem which occupy the same level in a food chain.There are five main trophic levels within a food chain, each of which differs in its nutritional relationship with the primary energy source.The primary energy source in any ecosystem is the Sun (although there are exceptions in deep sea ecosystems). all of these findings are critical and needed quickly intervention to call the provider to get an order for fluids and blood infusion to fix . The morbidity and mo Food chains, food webs and ecological pyramids are all ways to model trophic levels. An effect on a trophic level caused by a change in another trophic level.
