why it is useful?​

Answer 1

Hey mate..

here is your answer

Ecosystems provide various functions and services that directly or indirectly benefit us as a human. We, humans, are actually part of the ecosystems itself that should be living in harmony with other organisms. There are countless ecosystem functions and services, but I will give you some understandable examples.

Forest ecosystems supplies oxygene. We definitely need oxygene, unless you could breath by carbondioxide or nitrogene.

All crops and fruits that we consume need insects to pollinate their flowers. without those insects from natural ecosystems, we would die soon, unless you are able to do artificial pollination to countless number of flowers of all plants in the entire planet.

Many of medicines are from natural compound that can be found in the ecosystems. So ecosystems also provides resources that are useful for human, not only as food, but also as medicine.

many more functions.

hope it helps you!!!

Answer 2

Biological diversity, or biodiversity, is the scientific term for the variety of life on Earth. It refers not just to species but also to ecosystems and differences in genes within a single species. Everywhere on the planet, species live together and depend on one another. Every living thing, including man, is involved in these complex networks of interdependent relationships, which are called ecosystems.

Healthy ecosystems clean our water, purify our air, maintain our soil, regulate the climate, recycle nutrients and provide us with food. They provide raw materials and resources for medicines and other purposes. They are at the foundation of all civilisation and sustain our economies. It's that simple: we could not live without these “ecosystem services”. They are what we call our natural capital.

Biodiversity is the key indicator of the health of an ecosystem. A wide variety of species will cope better with threats than a limited number of them in large populations. Even if certain species are affected by pollution, climate change or human activities, the ecosystem as a whole may adapt and survive. But the extinction of a species may have unforeseen impacts, sometimes snowballing into the destruction of entire ecosystems.

European diversity is unique, but the loss of biodiversity has accelerated to an unprecedented level in Europe and worldwide. It has been estimated that the current global extinction rate is 100 to 1000 times higher than the natural rate. In Europe some 42% of European mammals are endangered, together with 15% of birds and 45% of butterflies and reptiles. To list just a few examples, the Arctic fox, the Iberian lynx and the red squirrel are all under serious threat.
