Life on Earth: Biomes, Climates, Ecology, and Evolution is part of the Introduction to Environmental Science open course series. This course explores the vast diversity of life on Earth. We examine the evolution of life from simple single-celled microbes to the complex ecosystems that we find on Earth today. We learn how populations and communities function as ecosystems and why it is important to protect the biodiversity that is found in these complex living systems. Earth’s biomes and climates will be investigated to learn how organisms evolved to live in virtually every niche of our planet. We will also see how human activity can have very negative consequences for our planet’s health in terms of climate, ecosystems and life.
Upon completion of this course students should be able to:
- Define population ecology.
- Calculate population density.
- Summarize the role of predators in regulating populations.
- Identify factors that affect population dynamics.
- Identify sources of energy and nutrients and the differences between these two terms.
- Relate trophic levels, food webs, energy flow, and nutrient cycling within an ecosystem.
- Define a biome and an ecosystem and identify the various parts of these environments.
- Characterize Earth's major biomes in terms of temperature, precipitation, location, and organisms that you would find in each.
Target Audience: Undergraduate students and those with an interest in understanding the environment and climates of Earth a bit more.
