Net 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
Why don’t producers (plants) increase GPP in response to increasing CO2 in the atmosphere and thus reduce climate change?
Group of answer choices
Excess fertilizer from human activities reduces plant growth
High concentrations of CO2 are toxic to plants
CO2 concentrations are not increasing
Consumers will just eat more plants if they grow faster
CO2 is not the limiting nutrient for plants

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…arrow_forward
