Answer:
the process by which oxygen released into the atmosphere by photosynthetic organisms is taken up by aerobic organisms while the carbon dioxide released as a by-product of repiration is taken up for photosynthesis.
Explanation:
Plants use carbon dioxide in a process known as photosynthesis. During photosynthesis, plants give off oxygen as a waste product. Carbon dioxide moves from the air into the leaves of plants through tiny openings in the plant's leaves. Oxygen moves out of the plant leaf through these same openings
Explanation:
<em>The greenhouse effect is a process that occurs when gases in Earth's atmosphere trap the Sun's heat.</em> Gases in the atmosphere such as CO2, water vapor, methane, nitrous oxide, ozone and some artificial chemicals such as chlorofluorocarbons absorb and re-radiate the sun's energy maintaining the Earth's temperature at around 33 degrees Celcius, this happens especially with infrared light that wants to go back to space. This infrared heat spreads back to the land and oceans. This absorption does not happen with visible light, the radiation at 400-800nm easily passes through the atmosphere.

Answer:
D. Fissure
Explanation:
On the image, we have a fissure. The fissure is a linear volcanic vent through which there are eruptions occurring. The fissures are connected with the volcano, but they can be tens of kilometers away from the volcano, or even more. This makes them very dangerous, as they can occur pretty much everywhere around the volcano, suddenly erupting from bellow the ground, making explosions, cracking the ground, and causing fires.
