        Ecology | Science Trek

        This video segment from IdahoPTV's Science Trek explores the meaning of ecology and some of the vocabulary associated the study of how living and non-living things interact, e.g. biome, primary producer, food chain, and ecosystem. We learn the importance of the sun as the starting point for the flow of energy in an ecosystem.
