Introduction to Biology: Ecology

Rice introduces ecology through relationships among organisms and their environments. Community ecology and island biogeography lead into species interactions, population ecology and conservation. The final biosphere section connects the earlier ideas. This is a beginner route for learners interested in living systems at a wider scale than cells or molecules.

What you will learn

• Distinguish community and population ecology.
• Explain how species interactions affect an ecosystem.
• Connect ecological concepts with conservation questions.

Who this suits

Beginners; Rice lists no prerequisites for this introduction to ecology.

Before you enroll

Treat this as an academic biology course. Check the expected scientific vocabulary and methods before enrolling; a conceptual or data exercise does not replace supervised laboratory training.

Coursera offers paid enrollment or subscription access. Check the enrollment screen for assessment and certificate terms, trials and any financial-aid options. Provider access terms can change; review them before paying.

Put it into practice

Sketch a local food web using documented observations. Explain one indirect effect that could follow a change in the abundance of a species.
