Chapter 15, Problem 2LTB
Summary Introduction
To explain:
An expected decrease in population growth as a non-human population approaches
Introduction:
The carrying capacity is the highest population that an environment can sustain when are no limits to its resources. Although populations tend to grow exponentially, their growth is constrained by the resources needed for their survival and reproduction.

C. Intrinsic Rate of Growth
D. Exponential Growth
A population is expected to grow exponentially
when the population size is close but below the carrying capacity of the
environment.
when the population size is exceeding the carrying capacity of the environment.
when the birth rate changes as a function of the population
after a severe population bottleneck.
Distinguish between the exponential and logistic growth of a population and describe the nature of their growth curves. Define environmental resistance. What is the carrying capacity of an environment? Define and give an example of a population crash.
