The green house effect refers to gases trapping the heat energy reflected from earth’s surface.
gases trapping heat energy reflected from the earth's surface.
<u>Explanation:</u>
It is the greenhouse effect that made earth a planet that supports life. if there was no green house effect the earth would have been too cold to live on. Sunlight contains rays like UV and infrared.  
UV rays being harmful are blocked by the ozone layer in the stratosphere. Infrared rays that enter the earth’s atmosphere are trapped by the greenhouse gases like carbon dioxide, water vapour, methane etc. the trapped infrared rays help in providing warmth.

Answer;
C) It stores energy that comes from glucose.
Explanation; 
-ATP is a biomolecule that is a product of cellular respiration which is used as a store of energy and is the usable form of energy by the cell.
-ATPs are used as the main energy source for metabolic functions. They are consumed by energy-requiring (endothermic) processes and produced by energy-releasing (exothermic) processes in the cell.
-ATP is able to store and transport chemical energy within cells. Energy is released by hydrolysis of the third phosphate group.
