- Nitrogen availability is a limiting factor in crop production. * D. Disagree, because atmospheric nitrogen is about 80% and therefore nitrogen is readily available. A. Agree, because almost 80% of the atmospheric nitrogen (N2) is readily available. C. Agree, because atmospheric nitrogen must first be reduced to ammonia through N-fixation. B. Disagree, because only a small fraction of the atmosphere is composed of nitrogen gas.arrow_forwardThe direction of the arrows in a trophic chain (as the one in the figure below) represents...

Why might this be the case? The energy input for growing corn is lower than that for sugarcane. The energy input for growing sugarcane is lower than that for corn. The EROI for corn ethanol is higher than that for sugarcane. The net energy ratio of corn ethanol is negative. Corn ethanol is not a renewable energy source.arrow_forward
- 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…arrow_forwardModern day industrial agriculture: a. has had no impact on society. b.has increased our ability to obtain more food from the same area. c.has permanently improved soils, providing more food from less space. d. promotes reductions in use of pesticides and fertilizers e. has rapidly improved soils, allowing continuous conversion of new areas to croplandarrow_forwardA class is studying the tropic levels of an ecosystem.
