Reason: For most animal populations, the resources for growth are limited.
The correct option is A Assertion and reason are true, and the reason is the correct explanation of the assertion
The logistic growth model is followed by a population which inhabits a habitat with limited resources. In nature, most animal populations exhibit a logistic growth curve because in the real world, the resources in a habitat are always finite. Such populations initially show a lag phase during which they adjust to the environment and as they adapt to their environment, they begin maximum utilisation of their resources and start growing exponentially. As the finite resources start depleting, the population goes through a declining phase of growth and ultimately reaches a stationary phase (no growth) when the carrying capacity is reached. Carrying capacity (K) is the maximum number of individuals of a population that can be sustained in a given habitat.
Thus, we can say that as most animal populations live in habitats that have limited resources for growth, they follow a logistic growth model and hence it is considered to be more realistic.
Thus, both assertion and reason are true, and the reason is the correct explanation of the assertion.
