Longmire Biology Unit 2

OverviewToday our global environment is being stressed by many different factors, including habitat destruction, pollution, invasion of non-native species, global warming, and depletion of the

ozone layer. The more you understand about the complex relationships that drive our natural ecosystems, and the degree to which humans depend upon these ecosystems for their very survival, the better prepared you will be to make environmentally sound decisions in your

lifetime. The content and activities in the next two units will help develop the understandings and skills necessary to become an environmentally literate member of our society.

Essential Question (the BIG idea):How do energy and nutrients pass on through an ecosystem?

Key Topics:

Photosynthesis

- Light Reactions- Calvin Cycle- Plant anatomy

Cellular Respiration

- Aerobic vs anaerobic - Glycolysis- Krebs Cycle- Fermentation

Ecology

- Energy Flow- Producers and Consumers - Ecosystems- Biomes- Population

Objectives:

By the end of this unit, you will be able to…

a. Identify the living and nonliving components that make up an ecosystemb. Understand how energy flows through an ecosystemc. Gain an understanding of how various nutrients are cycled through

ecosystemsd. Understand the difference between ecosystems and biological

communitiese. Learn about the factors that shape the nature of biological communities

(e.g., climate and competition among organisms)f. Understand how the interactions among organisms within an ecosystem

affect the stability of the ecosystemg. Gain an awareness of the major types of biomes that occur throughout

the world
