Nature's pecking order: who eats whom, ranked like a corporate hierarchy nobody chose.
means A trophic level is the rung an organism occupies in a food chain, based on how many steps removed it is from sunlight — plants at the base, herbivores above them, then carnivores stacked up from there.
from Built from Greek 'trophe,' meaning nourishment or food, plus 'level' for rank or tier. The term entered ecology in the 20th century, when scientists started modeling ecosystems as energy pyramids — quantifying who feeds whom and how much energy leaks away at each step up the chain.
- level one
- plants, stuck making their own food, no complaints
- energy loss
- only 10 percent passes up each level
- why few predators
- too little energy survives to feed many apex species
- humans rank
- roughly 2.2, closer to anchovy than lion
