How Ecosystems Work | Biology | Ecology

Purchase DVD here www.greatpacificmedia.com Segment from the program How Ecosystems Work: Energy Flow and Nutrient Cycles. DVD Description Looks at the processes that are fundamental to all ecosystems. First the concepts of primary productivity, trophic levels, food chains, energy pyramids and the flow of energy through ecosystems are introduced. The program then explains how carbon, nitrogen, phosphorous and water cycle through ecosystems and how human activities can disrupt these cycles and throw them out of balance leading to accelerated eutrophication in lakes in the case of phosphorous imbalances and global warming in the case of carbon imbalances.

Biomes | Biology | Ecology

Purchase DVD here www.greatpacificmedia.com Segment from the program: Terrestrial Biomes: Deserts, Grasslands, and Forests. DVD Description Our Terrestrial Biomes DVD starts by introducing the four requirements of life - nutrients, energy, liquid water and temperatures appropriate for carrying out life processes and then goes on to explain the factors such as latitude, proximity to oceans, and elevation, that affect climate. Climates relationship to the type of vegetation found in a biome is then explained before introducing students to the major terrestrial biomes including tropical rainforests, temperate rainforests, deciduous forests, savannas, grasslands, chaparrals, taiga, tundra and deserts.
