Define Net Primary Productivity. To get this right, you must mention GPP in your answer (In a way that is useful).
Define productivity as the word is used in ecology. What is a pri-mary producer? What is the distinction between gross productivity, net productivity, and respiration? How is net productivity related to biomass (or standing crop)?
A group of researchers are assessing energy availability in a terrestrial ecosystem. The image shows the food web for this ecosystem. They set up three plots and assess the biomass of producers, primary consumers, and secondary consumers. Rabbits and grasshoppers feed on ground cover plants that grow on the forest floor. Plot 1 is composed of mature hardwood trees, and only 25% of the sunlight reaches the shrubs and grasses compared to plots 2 and 3, which have fewer trees and allow more sunlight to reach the forest floor.
Based on the food web shown here, which of the following best describes how the reduction in sunlight to the forest floor would impact the number of primary consumers (squirrel, grasshopper, rabbit, and deer) in plot 1 compared to the other plots?
A - Plot 1 will show an increase in deer only because they feed on trees.
B - Plot 1 will show a decrease in squirrels and rabbits, while deer and grasshoppers will increase.
C - Plot 1 will show a decrease in rabbits and…
