- Energy transferred from one trophic level to the next in an ecosystem is measured in calories, numbers, and in biomass. If a rangeland has a biomass of 100, 000g/m2 from the grass, how much biomass will be available in human beings who eat the cow that eat that grass?What happens if there’s a natural disturbance (drought) affecting the balance of the food chain so that the Sun +E can supply only 4 energy units per plant? Compute for energy units following the table above and answer the following questions: What is the effect of reduced energy supply (nutrients or food) to the plants? Which components received comparatively less energy in the disturbed food chain? What could be the consequences of the above? If human beings were the last component in this food chain, what would be the consequences of reduced nutrient supply to plants?The rate at which light energy is converted into chemical energy of organic molecules is which productivity of ecosystem?
- estimate the total primary production in the oceans (in million metric tons carbon) using the following information - 92% of oceans are open ocen with an average productivity of 125 gC/m2/yr - 8% of the oceans are coastal, with an average productivity of 2,000 gC/m2/yr - remember a metric ton is 1,000 KgFood Web Construction Directions: Construct a food web using the following organisms (grass,leaves,owl, snake,grasshopper,hawk,bird,caterpillar,rabbit) Use Words to Construct. And answer the question that follow 1What is/are the producer(s) in the food web? 2What organism(s) feed directly on plants? 3What is/are the secondary consumer(s) in the food web? 4What is/are the tertiary consumer(s) in the food web?In a corn field in Oklahoma, the net primary productivity is 150 grams/m2/day and the respiration loss is 33.3 percent. The insolation energy is 950 calories/cm2/day and one gram of corn is equivalent to 1700 calories. Find the gross productivity of the corn. Using the NPP, calculate the efficiency of photosynthesis for the corn.

Use the equations below to answer the following problems: Net Primary Productivity = Gross Productivity – Respiration Loss Efficiency = . NPP . X 100 Insolation Energy In a rice paddy in Southeast Asia, the insolation energy is 6,000,000 calories/m2/day. The gross productivity of the rice is 0.012 grams/cm2/day, and the respiration loss is 20 percent. One gram of rice is equivalent to 1000 calories. Calculate the net primary productivity of the rice. Find the efficiency of photosynthesis by the rice. Could you mostly help me set it up and find it?
