Which of the following does NOT help determine an aquatic ecosystem’s carrying capacity? a
available food
b
available space
c
the average age of the population
d
quality of water

Carrying capacity, or the maximum number of individuals that an environment can sustain over time without destroying or degrading the environment, is determined by a few factors: food availability, water, and space. These key factors have the ability to limit, or even reduce a population by lowering birth rates, increasing the death rate, or encouraging migration. For this reason, these are referred to as ‘limiting factors.’ When there are no limiting factors a population can grow exponentially
