Define ecosystem/ecological services. Explain in brief with regard to pollination.

Explanation

The processes by which the environment produces resources that we often take for granted such as clean water, timber and habitat for fisheries and pollination of native and agricultural plants is called Ecosystem /Ecological services.
The transfer of pollengrains to fertilize the ovaries of flowers is called pollination. It isan essential part of a healthy ecosystem. Most flowering plants require pollinators to produce fruits and seeds. So pollinators play a significant role in the production of more food crops in the world. Declines of pollinator activity could have serious economic repercussions throughout the world. The most important pollinator for Agriculture is Honeybee. Over 1,00,000 invertebrate species such as boes, moths, butterflies, beetles and flies serve as pollinators worldwide. At least 1035 species of vertebratós including birds, mammals and reptiles also pollinate many plant species. Continued declines in pollinator activity could mean rising costs for pollinator dependent fruits and vegetables and the disruption of entire ecological systems.
