In addition to overall enrollment being at a record level, the universityâs main-campus enrollment is at an all-time high of 53,672, which informal tabulations also indicate is the most for any single campus in Texas. Texas A&Mâs main campus enrollment was 50,227 last fall.
The trophic level is a measure of the position of an organism in a food web, starting at level 1 with primary producers, such as phytoplankton and seaweed, then moving through the primary consumers at level 2 that eat the primary producers to the secondary consumers at level 3 that eat the primary consumers, and so on.
The study marks the first time anyone took the trouble to calculate human trophic level â a measurement of a speciesâ position in the food web. While apex predatorsâ levels can go as high as 5.5, the global average trophic level for our species in 2009 was a piddling 2.21. Thatâs comparable to pigs and anchovies (the researchersâ examples), animals that are coincidentally also both popular pizza toppings (my commentary). Sample food web.
