Develop a comprehensive plan to study the population dynamics of an endangered species. Include logistical and exponential growth models in your analysis.

• Define the objectives of the study.

• Outline the methodology.

• Identify the key variables and data collection methods.

• Discuss how the results will inform conservation efforts.

What is logistic population growth?

• A growth pattern where the population size decreases over time.

• A growth pattern where the population size increases by a fixed number each year.

• A growth pattern where the population size increases rapidly at first, then slows as it approaches a maximum sustainable size.

• A growth pattern where the population size remains constant.
