NEET BIOLOGY

Detailed explanation-1: -Marine ecosystems are aquatic environments with high levels of dissolved salt. These include the open ocean, the deep-sea ocean, and coastal marine ecosystems, each of which has different physical and biological characteristics.

Detailed explanation-2: -The deep-sea habitat The deep-sea is the largest habitat on earth. The area reaches over 4 000m in depth and covers 53% of the sea’s surface, which in turn covers 71% of the world’s surface!

Detailed explanation-3: -The climate of the marine biome is mostly varied. Since it is the largest biome in the world, the climate varies from-40 degrees fahreheit to over 100 degrees. The average temperature is 39 degrees fahrenheit, but it is warmer near the equator where the direct rays of sun can pierce the water and warm it.

Detailed explanation-4: -Marine characteristics include high salinity, variable temperatures, a surface photic zone, and a deeper aphotic zone. Biodiversity varies by depth and location.
