Do you think humans have a responsibility to help the environment? Why or why not? 4. What grade do you hope to achieve this semester? 5. IdenJfy what you are going to do in order to achieve this grade.

Recall
What is a population? • Population = A group of the same species living
in the same place at the same time • Populations can be described in terms of their
overall size, density, and dispersion.

How Populations Grow
How do populations grow? • Populations that grow rapidly can be
represented by an exponential growth model

How do populations grow? • Exponential Growth = a period of time when a
population grows exponentially (increasingly faster) due to available resources
How do populations grow? • Exponential growth can only occur when
resources such as food, space, and mates are plentiful . • When these resources become limited, growth
will slow or stop.

How do populations grow? • We can diagram
exponential growth by plotting population size over a period of time. • Exponential
growth will resemble a “J-shape” curve.
