1 AnswerChemistry2 weeks agoEcosystsm Ecology?
A) As part of an experiment, you measure than an herbivore consumed 425 J of energy from a plant. 270 J of energy were lost as feces, 120 J were lost via respiration, and 35 J were allocated to new growth of the herbivore.
Use these data to calculate the production efficiency of this herbivore. Report your answer as a percentage. Round your answer to 1 decimal point.
B) You quantify the net primary production in a prairie remnant as 12,400 J.
On average, how much energy (J) is transferred to the primary consumer trophic level?
C) You quantify the net primary production in a prairie remnant as 12,400 J.
On average, how much energy (J) is transferred to the tertiary consumer trophic level?
Biology4 weeks agoCalculate the net ecosystem productivity?
You measure the net primary productivity of a nearby wetland ecosystem to be 10,900 kcal/m2/year. As part of your efforts you also quantify the respiration by consumers (11,100 kcal/m2/year) and producers (9,200 kcal/m2/year).
Calculate the net ecosystem productivity of this wetland ecosystem in kcal/m2/year.
