Why is the energy reduced at each level of the energy pyramid
Nostrana [21]

Answer: because every time something eats something 10% of the energy is passed on so it starts as 100% with plants photosynthesizing then the herbivore gets 10% of that energy. The carnivore that eats the herbivore gets 10% of the herbivore’s energy so by the time it gets to the top of the pyramid there is less and less energy to consume.

The poison cyanide binds to the last complex of the electron transport chain and prevents it from accepting electrons. Assuming
Marianna [84]

Answer:

ATP synthesis by oxidative phosphorylation will stop.

Explanation:

Cyanide inhibits cytochrome oxidase that passes electrons to the molecule oxygen. Cytochrome oxidase also pumps two protons from the matrix to the intermembrane space during electron transfer. Inhibition of cytochrome oxidase would not allow the transfer of electrons to oxygen and the whole electron transport chain would be stopped. There would not be any generation of proton concentration gradient to drive the process of ATP synthesis. Hence, ATP synthesis by oxidative phosphorylation will be stopped after cyanide poisoning in aerobic cells.
