- Approximately how many kilograms (kg) of carnivore (secondary consumer) biomass can be supported by an area of a field containing 100 kg of plant material (assuming 10% efficiency in energy transfer)? O 10 O 100 O 1 O 1,000productivity in above-ground biomass increment is greater in the estuarine stand than the island fringing stand productivity in litterfall is greater in the estuarine stand than the island fringing stand O productivity can be measured in part by measuring carbon in litterfall O productivity can be measured in part by measuring carbon in above-ground biomass increment subtracting above-ground biomass increment from litterfall provides the total productivity for a mangrove standWhich of the following statements about gross primary production (GPP) is FALSE? O It is a rate that can be positive or negative Some forests (e.g. temperate forests) become carbon sources in the winter because GPP is less than respiration One method to estimate GPP is to monitor the change in CO, concentration, because CO2 is consumed during photosynthesis O It is the amount of photosynthesis per unit time O It is the amount of solar energy converted into chemical energy per unit time
