Although some ecosystems may be insensitive to species loss, due to variations in ecosystem types, or the presence of multiple species that perform a similar role, or due to their relative unimportance, or because of other abiotic factors, it is clear that higher numbers of species are needed to ensure stable provision of ecosystem services. From the unicellular to the multicellular, from one-celled algae to giant blue whales, food is the universal need. The Importance Of Ecosystem Diversity. What is the importance of wildlife? It promotes various food chains and food webs. These seeds often sprout and grow new plants (seed dispersal). They help remove the weak and the sick as well as keeping the balance with competitors helping to ensure species diversity.

They provide numerous ecosystem services, such as providing food, shelter and water, helping to create pathways in forests, and identifying salt licks.These services not only benefit elephants, but other species as well. Wetlands are among the most productive ecosystems in the world, comparable to rain forests and coral reefs. The natural disaster prevention mechanisms in most ecosystems and other free services we all get from the surrounding environment are not easily replaceable or replicable, so maintaining biodiversity is important. An ecosystem is a community of living organisms (plants, animals and microbes) in conjunction with the non-living components of their environment (things like air, water and mineral soil), interacting as a system. Bees are vital for the preservation of ecological balance and biodiversity in nature. Economic importance of Grassland Ecosystem.
