About 70% of the planet's surface is covered by the waters of the oceans, lakes, rivers, streams, springs and glaciers.

Nitrification: the transformation of ammonia or ammonium (NH4 +) to nitrite (NO2) by a group of bacteria of the genus Nitrosomonas then these nitrites become nitrates (NO3) by other bacteria of the genus Nitrobacter.
True

are the living things that shape an ecosystem.
Biotic components

Water cycle occurs when the solar rays heat the water. The vapor rises to the troposphere as droplets. The water is evaporated and concentrated in the clouds. The wind moves the clouds from the oceans to the continents.

At deeper levels of the planet, carbon contributes to the formation of fossil fuels such as oil
True

is any living component that never affects another organism.
A biotic factor

The atmosphere is composed of 78% nitrogen.
True

Sunlight is the source of thermal energy required for the path of water from solid to liquid and vapor phases, and is also the source of atmospheric circulations that carry steam and moving clouds.
True

are non-living chemical and physical parts of the environment that affect living organisms and the functioning of ecosystems.
A biotic components

Carbon is one of the most important elements of nature. Combined with oxygen forms carbon dioxide (CO2) and carbon monoxide (CO).
True
400
The oceans contain about 90% of the carbon on the planet in the form of carbonate and bicarbonate.
False

involve the fluxes of chemical elements among different parts of the Earth: .
Biogeochemical cycles

Ammonification is the transformation of inorganic compounds to ammonia.
False

The oxygen cycle is closely connected to the carbon, as the process by which carbon is absorbed by plants (photosynthesis) results in the return of oxygen to the atmosphere, while in the process of breathing the opposite effect occurs .
True

are the most significant driver of human-caused climate change. But human-accelerated cycles of other elements, especially nitrogen, phosphorus, and sulfur.
