Answer:
In the electron transport chain, when the protons move down their concentration gradient, the electrons are transferred from one molecule to the other and energy is released.
Explanation:
During the rear stage of cell respiration or oxidative phosphorylation two processes are involved. Among which one is the electron transport proton gradient chain, in which protons are transferred from one to the other molecule.
In this process electron also releases energy to make an electrochemical gradient. In this chain oxygen accepts protons and chooses electron to produce water.
It’s rain forest tropical/rain forest
An ecological niche refers to an organism's specific behavior in its specific ecosystem.
There are many things that fall under this description. For example, by specifying an ecological niche, we could be talking about the behavior an organism is exhibiting when there is plenty of resources or when the resources in a certain ecosystem are scarce. This has to be taken in account together with the question whether he has to compete with other organisms in his ecosystem for those resources.
Hope this helps :)
