Answer:

<u>Option-(B):</u>Cycling of matter and energy.

Explanation:

<u>Cycling of matter and energy:</u>

On our planet there are a number of elements or materials present which make up the matter and energy system, as they involve the connection between on entity with another. There is a net flow of energy between any two systems, giving more space and chances for the different species to live or survive. And, that is the one of the reasons which makes life on Earth possible from millions of years, as energy is kept conserved.

photosynthesis and cellular respiration both use electron transport chains. what is the source of electrons for photosynthesis a
goldfiish [28.3K]

Water serves as an electron source in the electron transport process of photosynthesis. The electron is extracted from water by using solar energy.

What is the electron transport chain's source of energy?

The electron transport chain uses the energy released by oxygen and reduced compound reactions such as cytochrome c and (indirectly) NADH and FADH2 to pump protons into the intermembranous space, producing the electrochemical gradient over the inner mitochondrial membrane.

In photosynthesis, water is split to produce electrons in the presence of sunlight, a process known as the photolysis of water. The electrons are finally transferred to NADP+ by the chloroplast electron transport chain, where they are reduced to NADPH.

Therefore, In aerobic respiration, electrons from NADH and FADH2 are transferred to oxygen by the mitochondrial electron transport chain to reduce oxygen in the water.
