- Primary productivity varies from ecosystem to ecosystem.Explain?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 ProductivityNet primary productivity refers to the rate of energy storage as organic matter by autotrophs after respiration is deducted the total rate of photosynthesis, or energy assimilated, by autotrophs the amount of accumulated organic matter found in an area at a given time the production of new tissues and offspring by heterotrophs
- What is the difference between gross primary productivity and net primary productivity.A family travels from New York City to Costa Rica three times a year for a vacation. The family would like to purchase some forested land in the Catskills, keeping the trees intact as an offset to the carbon dioxide they produce travelling each year. How much forest must they purchase? Use the following assumptions to measure the carbon offset provided by this intact forest. • The biomass of the forest increases at an annual rate of 2.8 × 105 kg/ha. • The forest biomass is 45% carbon by mass. • There are four people in the family. • 0.2 kg of CO2 is produced each mile per person on the flight. • The round-trip distance is 4,500 miles. • There are 2.47 acres in one hectare. 1. Calculate the mass of carbon, in kilograms, that is accumulated and stored in 1.0 ha of this forest in one year. 2. Calculate the mass of carbon, in kilograms, that is emitted by the family as a result of their round-trip flights to Costa Rica each year. 3. Calculate the number of acres of forest that must be…A family travels from New York City to Costa Rica three times a year for a vacation.
