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.
Green plants and algae occupy the producer level because they can use the energy of the sun, plus carbon dioxide and water, to produce glucose and oxygen. The next trophic level is primary consumer or herbivore. These are organisms that gain food energy by eating the producers. An example is a caterpillar consuming leaves or a rabbit feeding on crops. The next trophic level is the secondary consumer.
