Biology: The Science of Life: Ecology: Organisms in Their Environment DVD
This fifteen-minute program examines the interactions between organisms in their environments. The program addresses two important questions posed by core-curriculum standards: What are ecosystems and how do organisms interact in them? How do matter and energy flow in the environment? The concepts of ecosystem, population, niche, food chain, food web, food pyramid, and the carbon cycle are all explained in this very useful program.
