Population Ecology

- In the logistic growth equation, each term has a specific ecological meaning:
- = population density at time
- = carrying capacity of the environment
- = intrinsic rate of natural increase (or per capita growth rate)
- The intrinsic rate of natural increase defines the potential growth rate of a population under ideal environmental conditions with unlimited resources.
Thus, in the equation , ‘r’ specifically refers to the intrinsic rate of increase.

- Statement I is correct: A population is defined as a group of individuals of the same species living in a specific geographic area at the same time.
- Statement II is correct: A community refers to populations of different species living together in a habitat and interacting with one another.
- Statement III is incorrect: It wrongly defines a population as consisting of different species, which is the definition of a community, not a population.
