Solved in 2 steps
- Difference between Primary and secondary productivity.Distinguish between gross primary production and net primaryproduction.What is Primary Production and what are the factors that limit primary production in terrestrial and aquatic ecosystems. Give examples of where some of the most productive systems are on land and in water. Distinguish between Gross Primary Productivity and Net Primary Productivity
- What is the difference between primary productivity and secondary productivity?Explain the different ways in which primary production isinfluenced in terrestrial and aquatic ecosystemsIdentify the five ways that poor agriculture practices degrade our soils. Give typing answer with explanation and conclusion
- List three criteria for sustainable biofuel production.What is the difference between gross primary productivity and net primary productivity.In shallow coastal ecosystems dominated by seagrasses, nutrients limit primary production under low nutrient (oligotrophic) condition while light becomes the limiting factor under high nutrient (eutrophic) condition. In the conceptual model given below, identify which group of primary producers (i.e. seagrasses, macroalgae, phytoplankton) corresponds to each of the line graphs by filling in the blank boxes. Explain your answer.
- Discuss potential sources of biomass and biofuels that can be found in Mindanao particularly in Davao. Explain the possible conversion technologies and applications for these sources.Give brief description of factors that affects primary productivity.Define Net Primary Productivity. To get this right, you must mention GPP in your answer (In a way that is useful).
