1. There are three levels of biodiversity:
Genetic diversity: It refers to the variation in gene within a species. …
Species diversity: It refers to the variety of species within a region.
Ecosystem diversity: It include all the species and all abiotic factors characteristic of a region.
2. In ecology, a biological interaction is the effect that a pair of organisms living together in a community have on each other.
The biological interaction involves single-celled microorganisms, including fungi, bacteria, protozoa, viruses, and amoebae, and multicellular organisms, such as earthworms, arachnids, nematodes, and mites.
3. Biodiversity provides functioning ecosystems that supply oxygen, clean air and water, pollination of plants, pest control, wastewater treatment and many ecosystem services. Recreation—many recreational pursuits rely on our unique biodiversity , such as birdwatching, hiking, camping and fishing.
4. Climate change interacts with threats such as habitat loss and overharvesting to further exacerbate species declines. The decline of species and ecosystems can then accelerate climate change, creating a feedback loop that further exacerbates the situation.
