If arranged in an energy pyramid, which organism would contribute the least amount of usable energy?
a. wolf
b. rabbit
c. mouse
d. grasses

wolf

Explanation:

Only a small portion of energy is passed from one trophic level to the next successive level. The rest is lost to the environment through respiration, excretion and decomposition.

The biomass in the producers is more than that of the successive level in order for it to support the successive level therefore because the wolf belongs to the highest trophic level,it will have the least amount of usable energy.

Wolf

Explanation:

Just took the test.

1. the energy lost to disorder metabolism     -entropy

2. related to or possessing motion potential     -kinetic

3. all of the chemical reactions in an organism required for maintenance of the processes of life entropy     -metabolism

4. possible; ability to go into action or perform work kinetic     -potential

5. the study of energy and its transformations thermodynamics     -thermodynamics

step 1: nitrogen fixation- conversion of atmospheric no₂ into forms useful to plants by lightning, bacteria, and cyanobacteria.

step 2: nitrification-process of converting ammonia to nitrite or nitrate.

step 3: assimilation-plant roots absorb new form of nitrogen.

step 4: ammonification-conversion of organic nitrogen to ammonia by bacteria involved in decomposition.

step 5: denitrification-bacteria turns the decomposed matter back into n₂o, which is released into atmosphere; repeat cycle.
