Cells<span> need a source of </span>energy<span>, they </span>get<span> this </span>energy<span> by breaking down food molecules to release, the stored chemical </span>energy.This process is called 'cellular<span>respiration'. The process is happens in all the </span>cells<span> in our body. Oxygen is used to oxidize food, main oxidized food is sugar(glucose).</span>
Chemical energy: When animals eat plant, they get the chemical energy in the plants stored as sugar.Mechanical energy: Carbon dioxide rising through the air gains mechanical energy (as well as gravitational potential energy).Thermal energy: The heating of fossil fuels releases the energy stored inside.Electrical energy: Burning fossil fuels creates electrical energy for us to use.
Answer:
Weathering describes the breaking down or dissolving of rocks and minerals on the surface of the Earth. Water, ice, acids, salts, plants, animals, and changes in temperature are all agents of weathering.
Depending on what you've been learning in bio so far, the glucose is used in a process called glycolysis, which basically turns the glucose into ATP (Energy) which the cell can use.
Threatened means they are lowering in numbers and nearing to be endangered.
Endangered means they are dangerously close to being extinct
Extinct means there is none of them left in the wild.
I hope this is what you meant.
