Comparatively greater energy is released when a. carbon dioxide is the final electron acceptor. b. hydrogen is the final electron acceptor. c. nitrate is the final electron acceptor. d. oxygen is the final electron acceptor.

D. oxygen is the final electron acceptor.

Explanation:

Oxygen serves as the final electron acceptor in aerobic cellular respiration. The whole pathway includes glycolysis, Kreb's cycle, and oxidative phosphorylation.

Oxidation of NADH and FADH2 formed during glycolysis and Kreb's cycle through electron transport chain during oxidative phosphorylation includes molecular oxygen as the terminal electron acceptor.

The proton motive force generated during the electron transfer from NADH and FADH2 to oxygen gas drives phosphorylation of a large number of ADPs into ATPs.

explanation:

answer: grassland biomes are closer to the equator and receive more rain.

grasslands are biomes that are dominated by grasses rather shrubs and trees. savanna are biomes that exhibit grasses, shrubs and small tree as vegetation. grasslands are located near the equator of the earth. these are found in north america. savanna biomes are found in africa, south america, australia and india. grassland exhibit moderate climatic conditions, it receives   amount of rainfall higher than savanna.   therefore, savanna exhibit dry and hot climatic conditions.
