The three major deserts, namely tropical deserts, temperate deserts and cold deserts.
Usually, deserts have low precipitation (rain fall) and warm temperatures during day

The term ocean acidification is defined as increased concentration of acidic compounds
in ocean due to acid rain and pollution. The increased acid content in oceans and other
ecosystems affects the life and kills them, which results decreased fauna. For e
The aquatic life zone that has more salinity (sodium chloride) is called marine ecosystem.
71% of aquatic ecosystem is covered by the marine ecosystem; therefore it contributes
important economic services and ecosystems. The marine ecosystem is divided in
The tropical rainforests are one of the major grassland ecosystems. They have moderate
rainfall and cool winters and hot summers. Cutting of plants in tropical rainforest results
soil erosion, therefore soil will lost the vigor and quantity of nutrients.
