At some point, categories like herbivore/parasite/predator break down. (for example, small insects that eat small amounts of large plants, over a long time, seem to conform to the definition of a parasite.) why is this?

a chair, a bed, and a toothbrush

explanation:

i was told this before by a teacher, so yeah

ecological efficiency: % of usable energy transferred as

biomass from one trophic level to the next typical is 10% efficient (90% of

energy is lost),is diagramed as the pyramid of energy flow. then osprey eagle

are tertiary consumer and the shrimp are primary consumer, so to balance

mass of shrimp (1/0.1) / 0.1 = 100 kg
