The Earth's atmosphere would have little or no oxygen. A by-product of photosynthesis is oxygen. Photosynthesis is the process by which green plants use energy from the sun to make their own food in the leaves. The process uses sun light, water and carbon dioxide to yield oxygen and simple sugars. The simple sugars are stored in form of starch for future use by the plants, while oxygen is either used for cellular respiration or released to the atmosphere. The process of photosynthesis adds oxygen to the atmosphere and uses carbon dioxide from the atmosphere.
While doing exercise, one can control skeletal muscles only.
The body has three kinds of muscles, that is, skeletal muscle, cardiac muscle, and smooth muscle. The skeletal muscles are linked with the bones of the skeleton, that is why these are under control and are known as voluntary muscles.
On the other hand, the smooth muscles like skeletal muscle can never be under control. These muscles helps in pushing substances, like blood or food through organs. The cardiac muscle is also an involuntary muscle, which is found only in the heart. These muscles helps in contraction of the heart and can never be controlled.
