Detailed explanation-1: -Biodiversity supports human and societal needs, including food and nutrition security, energy, development of medicines and pharmaceuticals and freshwater, which together underpin good health. It also supports economic opportunities, and leisure activities that contribute to overall wellbeing.
Detailed explanation-2: -Declining biodiversity lowers an ecosystem’s productivity (the amount of food energy that is converted into the biomass) and lowers the quality of the ecosystem’s services (which often include maintaining the soil, purifying water that runs through it, and supplying food and shade, etc.).
Detailed explanation-3: -Biodiversity is essential for the processes that support all life on Earth, including humans. Without a wide range of animals, plants and microorganisms, we cannot have the healthy ecosystems that we rely on to provide us with the air we breathe and the food we eat. And people also value nature of itself.
Detailed explanation-4: -how might a reduction in species diversity affect the other three components? by reducing genetic info and the specific traits of organisms. this reduces potential adaptations. it also affects the maintenance of ecosystems by affecting resources/services.
