Chapter 44.6, Problem 1TYK
Net primary production is
- the energy that passes from plants on to herbivores.
- gross primary production minus the energy used by herbivores.
- the energy fixed in photosynthesis.
- the energy fixed in photosynthesis minus the energy used in respiration of photosynthetic organisms.
- gross primary production minus the energy used by consumers.

Students have asked these similar questions
Ethanol from sugarcane has a medium net energy yield, while ethanol
from corn has a low net energy yield. 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.
Net primary productivity is the primary productivity of an ecosystem, after
subtracting energy lost in
inedible plant tissues.
respiration by primary producers.
dead plant tissues.
O respiration by primary consumers.
inefficiencies of photosynthesis.
A trade-off of heterotrophic carnivores in gaining energy is that food is:
scarce but it's easy to capture and kill their very nutritious food.
abundant but it's nutritious.
scarce but it's nutritious.
abundant but it's difficult to capture and kill their very nutritious food.

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 timearrow_forwardAs scientists research and develop biofuels, they are faced with many tradeoffs. A plant's usefulness for biofuels depends on how much energy can be collected from the plant matter. In addition, growing plants on a large scale requires energy—such as the gasoline and power needed to run tractors and other harvesting equipment or the energy needed to create and distribute fertilizers and pesticides. An efficient biofuel would maximize the ratio of energy output to energy input. The following graph illustrates the results of a 10-year study analyzing three different crops used in biofuel production. The data show how much energy was required to grow each crop on 1 hectare of land (energy input) and how much energy was recovered from the total crop on each hectare of land (energy output). A hectare is a measurement of an area of land and is roughly the same as 2.5 acres. What was the estimated energy input of the grass? A. kcal x 10^6 B. 2kcal x 10^6 C. 8kcal x 10^6arrow_forward
