In photosynthesis, light energy drives the transfer of electrons from to .

In photosynthesis LIGHT ENERGY drives electrons from a low energy state in water to a high energy state.

Explanation: Photosynthesis is the process used by plants, algae and cyanobacteria to utilize energy from sunlight and turn into chemical energy.

There are two types of this process: oxygenic photosynthesis and anoxygenic  photosynthesis. The general principles of both of them is very similar, however oxygenic is the most regular to see in plants, algae and cyanobacteria.

The oxygenic photosynthesis begins when the light energy transfers electrons from water  to carbon dioxide, so that carbohydrates can be produced.  During this transfer, CO₂ is reduced  or receive electrons and the water becomes oxidized, meaning, it loses electrons. The oxigen is produced along with carbohydrates.

Hope this helps:)

eukarya because is is like alche and b is bacteria and d is animals

explanation:

when you breathe in, or inhale, your diaphragm contracts (tightens) and moves downward. this increases the space in your chest cavity, into which your lungs expand. the intercostal muscles between your ribs also enlarge the chest cavity. they contract to pull your rib cage both upward and outward when you inhale.
