Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Photosynthesis is important because
A
it provides the oxygen we breathe and the food we consume to survive
B
it provides the carbon dioxide we breathe
C
it provides the Earth with fresh water
D
it makes plants green
Explanation: 

Detailed explanation-1: -Photosynthesis is important to living organisms because it is the number one source of oxygen in the atmosphere. Without photosynthesis, the carbon cycle could not occur, oxygen-requiring life would not survive and plants would die.

Detailed explanation-2: -Humans depend on photosynthesis to make the food they consume, as a source of energy to produce heat, light, and electricity, on a daily basis. Additionally, autotrophs are producers in almost all food chains, therefore this mechanism is essential for humans as well.

Detailed explanation-3: -Photosynthesis is important to food chains because creatures capable of photosynthesis form the foundation of most food chains. In other words, they are the producers, capable of using solar energy to create their own food. Organisms that can produce their own food are also called autotrophs.

Detailed explanation-4: -Through photosynthesis, humans can again breathe in the oxygen that was produced and survive. Photosynthesis and respiration are the two essential processes that allow life to sustain on earth.
