Integrative Biology
102: Lecture Outline
Energy Flows, Matter Cycles
Lecture Objectives
By the end of this lecture and
reading the text, you
should be
able to:
- give examples of biotic and abiotic
components
within an ecosystem.
- contrast and explain the flow of
energy and the cycling of matter in ecosystems.
- give an example of a food web.
- list the four basic types and functions of organic compounds in
living organisms.
- describe and diagram the carbon and
nitrogen cycles.
- list the anthropogenic changes to these cycles and describe the
effects of these changes.
- explain the concept of limiting
factors.
