“Chlorophyll stores chemical energy needed for photosynthesis” is the answer
Answer: hope this helps
Explanation:
Aerobic bacteria use oxygen, which is added mechanically, to break down wastewater contaminants, converting it into energy. Bacteria use this energy to grow and reproduce. Anaerobic bacteria obtain oxygen from their food source. As anaerobic bacteria break down sludge, they produce methane gas. This methane gas can be used as an alternative energy source, called biogas, to fuel the wastewater treatment process.
Before a chemical reaction can start energy must be absorbed by the reactants. The amount that must be absorbed to start the reaction is called the activation energy. you're right, t<span>he activation energy must be reached.</span>
This answer is B because it is not made up of cells, the easiest way to know this is because viruses are much smaller than a single cell, meaning its impossible for it to have cells or be a living organism.
