what is a trophic level in biology

Trophic Level | Definition , Types & Examples

The trophic pyramid is a graphical way to show the movement of energy throughout the food chain. The amount of available energy decreases as we move up the trophic levels. This process is not the most efficient. It is estimated that only approximately 10% of the energy consumed ends up as biomass as we move up each trophic level.

Apex predators, which are at the top of the food chain and are the highest trophic level in an ecosystem, have a top-down effect on the rest of the food chain.Removing apex predators from a food web has a snowball effect on the populations of species lower in the web. Removing the producers has a top-up effect as it removes the essential base energy from the equation.
