Tundra soils are generally frozen and are categorized as Gelisols. And in order to be a Gelisol, permafrost must be within 100cm of the soil surface.
Question:
Solution (explanation):
Greenhouse gases are those gases that accumulate in the Earth's atmosphere and absorb infrared energy from the Sun. This creates the so-called greenhouse effect, which contributes to the increase in the global temperature of the planet. Now, the higher the concentration of greenhouse gases, the greater the retention of heat. These extra gases increase the natural greenhouse effect and cause global warming which leads to a global change in the climate.
Answer: we can conclude that the correct answer is:
Greenhouse gases
Answer:
from the splitting of water molecule.
Explanation:
The splitting of water molecules by sunlight is called Photolysis. This is the first reaction in photosynthesis; which occurs by catalysis of enzymes of Photo system 11.
It involves the splitting of water molecules into;
hydrogen ion/protons.
Oxygen
and electron.
<u> Oxygen is the by product liberated into the atmosphere, for animals to inhale for the process of cellular respiration</u><u>.</u>This is the source of oxygen fro cellular respiration in animals.
the hydrogen ions combined with electrons from photosystem 1 to reduce NADP .The latter is used to reduce C02 to form carbohydrate in light independent reaction
