The need for energy, gained by respiration and photosynthesis, is the driving force of the oxygen cycle.

In a way, yes. It can also be said that the driving force of the oxygen cycle is photosynthesis itself, which is responsible for the creation and maintenance of earth's atmosphere.

Photosynthesis occurs in green plants, which use energy  from sunlight to convert carbon dioxide and water into carbohydrates. During this process, water molecules are split and oxygen is released as a by product.

It can thus be said that plants take in or "breathe in" carbon dioxide and release or "breath out" oxygen in to the atmosphere.

The Answer Is T R U E

frogs. the lower the ph the higher the acid content. frogs have the highest tolerance in this scenario.

transformative rocks are the stones that emerge from the transformation of existing rock composes in a procedure called changeability, implies changing of structures. transformative rocks are shaped from alternate shakes that are changing a result of warmth or weight connected. one of this model is the earth developments that making rocks profoundly cover or crushed which will make the stones warmed and put under awesome weight. they are not softening but rather the minerals they are containing are changed synthetically that will shape transformative rocks. now and again different rocks are shaped when the others are near some liquid magma and getting warmed.
