Trophic Levels

In ecology, the trophic level is the position that an organism occupies in a food chain - what it eats, and what eats it.

Wildlife biologists attending at a accustomed "economy of energy" that ultimately rests aloft solar energy.
When they attending at an ecosystem there is about consistently some foundation breed that anon harvests activity from the sun, for example, grass (however in abysmal sea hydrothermal vents chemosynthetic archaea anatomy the abject of the aliment chain).
Next are herbivores (primary consumers) that eat the grass, such as the rabbit.
Next are carnivores (secondary consumers) that eat the rabbit, such as a bobcat.
There can be several average links, which agency that there can be addition band of predators on top, such as abundance lions, which sometimes eat bobcats.
Since anniversary band of this arrangement relates to the one beneath it by arresting a atom of the activity it consumed, anniversary one can be accepted as comatose on the one beneath - which is alleged a lower trophic level.
Keep in apperception that trophic relationships are rarely this simple.
Very generally they are added of a "web" than a "chain." For example, the abundance bobcat may eat the bobcat, but it aswell eats rabbits.
The trophic analysis of the abundance bobcat exists on two levels, possibly more.
