1the carrying capacity for a species in an ecosystem is primarily determined by
oa the ecosystem's resources
b the number of predators
c the species' fertility
da boom-and-bust curve

c number is the right answer of the following

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
