The atmosphere interacts with the hydrosphere through the water cycle.
Water cycle:
• Evaporation of water (from the earth’s surface-due to the heat from the sun,
• Cold Trap- a point reached by the water vapor when it gets higher into the atmosphere (this point is substantially colder than the air below it)
• Condensation of water- the water vapor turns into water droplets as it cools down, they connect to form clouds
• Precipitation of the watee- water falls in the form of which is usually rain.
The water flows into rivers, streams, and fall directly into the ocean, where the cycle can restart.
.Most life-forms that existed on Earth have become extinct.
<span>.Dinosaurs existed on Earth for more than 544 million years.
Both these statements are well suported by fossil record.</span>
Colonies of cyanobacteria benefit aquatic organisms because they can be an important source of food to organisms.
The problem with cyanobacteria is that they can be harmful and in an alga bloom then can cover the surface cutting off any light to other plants and producing toxins that kill fish and other life forms.
The phylum of fungi that consists of decomposers that utilize flagellated spores is option, B. Chytridiomycota. Chytridiomycota, also known as chytrids are considered as a unique fungi because of its characteristics and traits are different from the rest of the common fungi. These fungi are known to have zoopores or motile cells in a form of flagellum.
