Answer:
By releasing the oxygen during the photosynthesis, and releasing the CO2 during the cellular respiration
Explanation:
The balance of gases in the atmosphere must be maintained.
Photosynthesis is a process performed by the plants (also some algae and bacteria) in which the energy of sunlight is transformed into chemical energy usable by those plants. Necessary components of this set of reactions are sunlight, water and CO2, while resulting products are glucose and oxygen. Products of photosynthesis are then used in the metabolic processes known as cellular respiration. During the cellular respiration, glucose and oxygen are used for the production of ATP, CO2 and water. Cellular respiration is performed in all living organisms.

How does weight effect the distance a paper airplane will fly?
Answer: Hurricanes
Explanation:
Hurricanes are formed from warm ocean water especially in the tropics and strong winds. The process occurs when warm air above the warm ocean water is continually replaced by cooler air in the atmosphere . This continuous cycle causes the hot air to move upwards, cool and condense into clouds together with the growing strong winds and constant evaporation from the warm oceans causing a mighty storm spining upwards which intensifies as wind increases causing hurricane to form.
Tiktaalik is a transitional fossil which shows how fish evolved into amphibians and reptiles. So the correct option is B.
What is Tiktaalik?
Tiktaalik is a direct ancestor of tetrapods or four-legged animals. It is an extinct fish-like animal and it lived on earth 380-385 million years ago (Devonian period).
The word Tiktaalik is derived from the <em>Inuktitut</em> language which loosely translates to large freshwater fish. This animal had characteristics of both fish and tetrapod and is therefore called the link between these two kinds of animals.
The characters resembling fish are gills and scales and the characters resembling tetrapods are rib bones, movable neck and lungs. There are characters that are a mix of both tetrapods and fish. These are bones and joints in limbs but fish-like fins instead of feet or hands.
