Sunlight from the sun hits the leaf of the plant.
Location 2 is cooler than Location 3 and Location 1 because it's at a higher altitude
The increase of carbon dioxide in the atmosphere creates a greenhouse effect.
To explain this usually some sunlight is reflected back into space while some is absorbed by the earth keeping the planet warm. However the increase in greenhouse gases such as carbon dioxide prevent the light from reflecting back into space and this light becomes trapped causing the earth to heat more then it should. You can almost think of the trapped heat from the greenhouse gases as a blanket around the earth trapping the heat in.
Yes that statement is true
The right choice of them is biosphere, community, and organism.
