1) Why is photosynthesis and example of a chemical reaction, and why is it classified as endothermic?
2) how do everyday activities like driving a car using electricity less to global warming?

you're not dumb
6CO2 + 6H2O + light energy = C6H12O6 + 6O2
That is the reaction and it makes oxygen out of CO2 which is the reverse of burning fossil fuels. It takes energy in (endothermic) as opposed to your fireplace or furnace which produces both heat and CO2 and other nasty stuff.
Your electric car uses electricity produced efficiently at the power plant or with no burning of fuel at all if you charge with a solar panel. When you burn fuel inefficiently (although they are getting better) in a car you produce CO2, carbon, CO and other greenhouse nastys.

thank you i got 100%
@damon am i just supposed to copy and paste that?
Photosynthesis requires energy, making it an endothermic reaction. Light, generally sunlight, is the source of this energy. The process converts the sun’s electromagnetic energy into chemical energy, which is then stored in chemical bonds in the plant. Sunlight is the primary source of energy on the surface of Earth. Re-word it
is made is by burning fossil fuels, like coal or fuel. When a fuel is burnt, some of the products are: carbon dioxide, carbon monoxide, and water - all of these gases are greenhouse gases. In a similar way driving a car also burns fossil fuels, and this will produce the same gases.
sorry I meant
