The open water of the ocean pelagic in some ways resembles the terrestrial desert. In a short essay of between 100-150 words, compare and contrast these 2 biomes.

Answer and Explanation:

Aquatic biomes are the water-based large geographical areas, while terrestrial biomes are land-based large geographical areas. Kelp forests, freshwater, estuaries, marine water, wetlands and coral reefs are forms of aquatic biomes. Tundra, forests, taiga, grasslands and desserts are the forms of terrestrial biomes. Aquatic biomes involve the formation of climate and water regulation and provide shelter for millions of kinds of fish. On the other hand, terrestrial biomes maintain the climate, provide food for living entities, absorb carbon dioxide from the air and release oxygen. Aquatic biomes are world’s largest biomes, while terrestrial biomes are smaller in size. Animals which live in the water are called aquatic animals, such as whale, dolphins, sharks, corals, sea horses and alligators. Aquatic animals breathe through their gills in order to absorb oxygen. Animals which live on land are called terrestrial animals, such as cats, tigers, lions, mice, oxen, bulls, dogs, spiders and many more. Terrestrial animals breathe through their mouths, noses and skin.

scientists have discovered that hiv does not cause aids by the virus's direct effect on the host's immune cells, but rather through the cells' lethal influence on one another. researchers from the gladstone institutes have revealed that hiv does not cause aids by the virus's

step 1: nitrogen fixation- conversion of atmospheric no₂ into forms useful to plants by lightning, bacteria, and cyanobacteria.

step 2: nitrification-process of converting ammonia to nitrite or nitrate.

step 3: assimilation-plant roots absorb new form of nitrogen.

step 4: ammonification-conversion of organic nitrogen to ammonia by bacteria involved in decomposition.

step 5: denitrification-bacteria turns the decomposed matter back into n₂o, which is released into atmosphere; repeat cycle.
