Answer:
3 (Cells carry out the respiration process)
Explanation:
Cellular respiration is a metabolic (catabolic) process common to all living things as all living things need energy for their life processes.
Respiration is the biochemical process in which the cells of an organism obtain energy by breaking down organic molecules in presence or absence of oxygen (aerobic or anaerobic) resulting in the release of Carbondioxide (CO2), water and Adenosine triphosphate (ATP).
Food molecules (containing stored energy in their chemical bonds) absorbed after digestion are broken down and the energy within their molecules are freed. This freed energy in form of ATP, is used to power the organism's movement and physiological functions.
Note that, ATP is an energy carrying molecule and a usable form of energy by cells. This is so because ATP releases energy quickly. Energy is released from ATP when the end phosphate (Pi) is removed to become ADP (adenosine diphosphate), which is a low energy molecule.
Aerobic cellular respiration consists of Glycolysis, Kreb's cycle and Oxidative phosphorylation. A total of 38 ATP molecules is produced in the cytosol of prokaryotes while a total of 36 ATP molecules is produced in the mitochondria of eukaryotic cells.

Explanation:
Reykjavik the capital city of Iceland heats its buildings using geothermal energy sources at a cost that is lesser of what it would be if oil were used.
In all ramification, the use of geothermal energy sources is far more preferable and better than using fossil fuels like oil.
- Geothermal energy is energy from within the earth
- It is natural and renewable source of energy.
- The cost of product is very low
- It has little to no impact on the environment as well.
- They are usually found where magma pockets are close to the surface
