Which of the following best explains the difference in the amount of available energy in the trophic levels of the desert ecosys
tem? A)There is less available energy in the fourth trophic level because of the loss of energy in the trophic levels of the desert ecosystem.
B)There is more available energy in the birds of prey because they have greater muscle mass for storing energy than organisms in lower trophic levels have.
C)There is less energy available in the producers because their tissues are less dense than those at higher trophic levels.
D)There is more energy available in the second trophic level because less energy is needed for hunting compared to the highest trophic levels.
There is less available energy in the fourth trophic level because at each successive trophic level only 10% of the available energy from the previous trophic level is transferred. This is called 10% law of energy transfer. Rest 90 % of the energy is lost as heat to the atmosphere through metabolic activities of the organisms in that level.
<span>The organic molecules that must be included in the soil for earthworm nutrition are Neutral pH. A neutral pH substance that is neither basic nor acidic is considered neutral. The pH scale is the one that measures how a substance is basic or acidic. It ranges from 0-14. A 7 pH is neutral.</span>
