Document Summary
Biomes: regions characterized by distinct abiotic characteristics and dominant types of vegetation. Different ecosystems may belong to the same biome o. Deserts in different locations are in the same biome. Each biome has a distinctive set of abiotic conditions determined largely by climate o. Certain enzymes only work efficiently in a narrow range of temperatures. Evaporates too quickly in high temp: moisture (important) Must be able to replace that water o. Total amount of biomass generated by the fixation of carbon per year minus the amount that is oxidized during cellular respiration o. Biologists see how temperature and moisture influence npp: organic matter that is available as food for other organisms. Biomass: total mass of organisms or primary producers. Aboveground biomass: total mass of living plants, excluding roots: used in terrestrial environments. Photosynthesis, plant growth, and npp are maximized when temperatures are warm and conditions are wet o o.
