Any substance that is involved in chemical reactions in a living organism.
1 of 11
Specific heat capacity
The measure of the amount of heat energy needed to heat up a particular mass of a material through a particular temperature rise.E.G Water
2 of 11
Thermophilic
Heat loving, such as the bacteria that live around hot springs and volcanic vents.
3 of 11
Ambient gases
The surrounding environmental gases that are available to organisms.
4 of 11
Atmosphere
The gases that surround the earth. Different layers are characterised by their temperature, density, turbulance and compostion.
5 of 11
Photolysis
The splitting of molecules by light, including the splitting of water molecules in the early atmosphere, producing oxygen.
6 of 11
Greenhouse gas
A gas that absorbs infrared radiation and causes atmospheric heating.
7 of 11
Transpiration
The loss of water by evaporation from the stomata of leaves.
8 of 11
Biosphere
All the living organisms on earth.
9 of 11
Hydrosphere
All the water on earth, found in solid, liquid or gaseous form in a variety of reservoirs, including the oceans, ice caps, rivers and lakes, soil, groundwater, atmosphere and living organisms.
