yes, everysingle thing either changes energy or stores it's energy. e.g. a colock stores it's energy, whilst a human uses its energy, but nothing produces energy we actually get energy from the sun and we change it, to what we need.
The main functions of chloroplast are to produce food (glucose) during photosynthesis,And to store food energy.
Solar
photosynthesis
Heat Energy is in everything. The sun provides heat for everything, even our bodies produce heat. Some other things that produce heat energy are: lights, computers, televisions, toasters, Phones, heaters, fridges and LOTS more.
Energy is stored in the cells. The cells travel around the organism (or a living system) and give off, or produce, energy.
monosaccharides
Yes,everything that has to eat something to get its energy. (producers produce their own food)
No, they don't. If a cell is to continue living it has to continue to produce the energy needed to sustain its activities.
Photovoltaic cells generate electricity when exposed to sunlight. They do not store energy themselves, but the electricity they produce can be stored in batteries or used immediately.
oxidation of the air that we inhale
Muscles store chemical energy from the food your body broke down, then your muscle turn those chemical energy to mechanical energy when they contract.
Energy is typically stored when there is excess energy generated that cannot be immediately used. This stored energy can then be used during times of high demand or when the primary energy source is not available. Various methods such as batteries, pumped hydro storage, and compressed air energy storage are used to store energy.
