Question

the carrying capacity of a population is the dotted line on this graph. it determines the maximum population size in the ecosystem. what letter do we use to abbreviate carrying capacity?

Explanation:

In ecology (a subfield of Natural Science, specifically Biology or Environmental Sciences), the carrying capacity, which is the maximum population size an ecosystem can sustain, is abbreviated using the letter "K". This is a standard notation in population ecology, related to concepts like logistic growth models where the population growth rate slows as it approaches the carrying capacity (K).

Answer:

K
