reflection of the amount of biomass produced. In order to produce biomass, energy must also be used to break down glucose through cellular respiration. The end result is your net primary productivity (NPP), GPP minus your cellular respiration rate. NPP is has a direct relationship with different environmental factors. The highest NPP will occur in tropical regions because there is an abundant amount of rainfall and light. An abundant amount of water is needed for increased photosynthesis since water is lost to evaporation. If the soil is too wet and becomes water-logged, this will decrease NPP since the roots cannot respire. The temperatures also affect photosynthesis. If it is too hot or cold, most plants cannot photosynthesize and NPP will be reduced. The length of the day will have a linear relationship with NPP, because the more light that is available the more photosynthesis that can occur. Different environmental factors play a huge role in decomposition rates and efficiency. The rate of decomposition is a great factor in the NPP of an ecosystem. The faster that turnover can happen, the sooner they are available for plant uptake and NPP will increase. Bacteria activity is greatly influenced by both temperatures and moisture so a tropical environment is best. If it is too cold or hot like the desert or arctic, microbial activity will decrease. Decomposition rates are faster in southern latitudes because of the warm and moist climates. If the environment is too wet, like a swamp or marsh, decomposition rates are at the slowest. Anaerobic bacteria cannot survive in standing water so this will result in dead organic matter building up. Areas like the tundra that are both cold and wet will have the slowest decomposition rates and NPP is the lowest. Page 5 of 5 Review Test Submission: Unit VI Assessment – BIO 1302-...
