BASICS OF ECOLOGY
Populations: Biotic Potential, Environmental Resistance
After watching "Populations: Biotic Potential, Environmental Resistance" students will be able to:
- Define the terms biotic potential and environmental resistance.
- Describe exponential growth and why it isn’t very common in the natural world.
- Define the term ‘carrying capacity’ and explain how it impacts the growth of species populations.
- Explain environmental resistance.
- Contrast and compare density-dependent and density-independent limits to growth.
- Describe how predators, parasites, and competitors affect the growth of a population.
- Discuss the factors that lead to variations in the distribution of populations in space and time.
- Describe the differences between concave, convex, and constant survivorship curves.
- Describe how births, deaths and migrations affect population growth.
