Ecosystem services

We get various kinds of natural resources from different ecosystems. For instance, a forest ecosystem provides us timber, medicinal plants etc. while we get the major share of our fisheries and many minerals from marine ecosystems. Along with providing the natural resources (called provisional service) any ecosystem silently gives other services also. It regulates the abiotic and biotic factor to make life possible in a specific area. Maintenance of the temperature and production of oxygen by the plants, removal of waste materials by microbes through the process of decomposition etc. are the examples of regulatory services provided by the ecosystem. Additionally, we use certain ecosystems for recreation, religious purposes etc. Such service given by ecosystems is called cultural service. The recreational benefits given by the mountains, beaches, usage of river banks for conducting religious rituals etc. are some examples of cultural service we get from different ecosystems. Here we may not be taking any resource from the ecosystems but the activities conducted in the ecosystems are essential to make humans happy and peaceful.
 

Let's watch the video of an aquatic ecosystem given below.

List out the resources and services we are drawing from this kind of ecosystem.
