Trophic level - Wikipedia
The trophic level of an organism is the position it occupies in a food web. Within a food web, a food chain is a succession of organisms that eat other organisms and may, in turn, be eaten themselves. The trophic level of an organism is the number of steps it is from the start of the chain. A food web starts at trophic level 1 with primary producers such as … See more
HistoryThe concept of trophic level was developed by Raymond Lindeman (1942), based on the terminology of See more
