Statement 1 is correct. Carrying Capacity refers to the maximum population size that an environment or ecosystem can sustainably support over a period without causing significant degradation or depletion of its resources.
Statements 2 and 3 are incorrect. When the number of individuals in a population exceeds the carrying capacity of the environment, the population will experience a decline. The carrying capacity of an environment can change over time. For example, the carrying capacity of a forest for deer can decrease if the forest is logged or if the deer population grows too large.
