Which ecosystems have highest and lowest biodiversity and species diversity increases probability of adaptation & survival of organisms in changing environments?
Increased genetic diversity leads to increased chance of species survival. Species with a limited variety of phenotypes and where all members of the species are similar to one another have a smaller chance of coping with environmental variability compared to a species with greater diversity. The idea of natural selection is that traits that can be passed down allow organisms to adapt to the environment better than other organisms of the same species. This enables better survival and reproduction compared with other members of the species, leading to evolution. Evolutionary adaptation, or simply adaptation, is the adjustment of organisms to their environment in order to improve their chances at survival in that environment. All organisms need to adapt to their habitat to be able to survive. This means adapting to be able to survive the climatic conditions of the ecosystem, predators, and other species that compete for the same food and space. Maintaining high genetic diversity allows species to adapt to future environmental changes and avoid inbreeding. Inbreeding, which happens when there are small, isolated populations, can reduce a species' ability to survive and reproduce.The greater the genetic diversity within a species, the greater is the chance of that species to survive. Conversely, the lower the genetic diversity within a species, the lower is the chance of survival. This is because unfavorable traits, such as inherited diseases, may become widespread within a population.Primary abiotic factors are light, temperature, water, atmospheric gases, and ionizing radiation, influencing the form and function of the individual. For each environmental factor, an organism has a tolerance range in which it is able to survive. They include factors such as light, radiation, temperature, water, chemicals, gases, wind and soil. In some environments, such as marine environments, pressure and sound can be important abiotic components. Amazon River abiotic The Amazon River provides and removes excess water to and from the environment. Estuarine areas have high biodiversity compared to other areas. Trophical rainforests are rich in terms of biodiversity. Arid and semiarid areas have low biodiversity. Tropical forests are widely considered to have the greatest species diversity of the terrestrial biomes and the tundra biome has the least. Wetlands have been called “biological super systems” because they produce great volumes of food that support a remarkable level of biodiversity. In terms of number and variety of species supported, they are as rich as rainforests and coral reefs.The Andaman and Nicobar islands is the region with maximum biodiversity. The state which has the least biodiversity is Rajasthan because a large percentage of the total area is desert.
Genetic variations create diversity within a species. Changes in environmental factors such as habitat loss, increased pollution, climate change, and invasive species can challenge the survival of members of a population. Organisms that survive pass their traits on to offspring. Evolutionary adaptation, or simply adaptation, is the adjustment of organisms to their environment in order to improve their chances at survival in that environment. The idea of natural selection is that traits that can be passed down allow organisms to adapt to the environment better than other organisms of the same species.

Species with a limited variety of phenotypes and where all members of the species are similar to one another have a smaller chance of coping with environmental variability compared to a species with greater diversity. Evolution and diversity result from the interactions between organisms and their environments and the consequences of these interactions over long periods of time. Organisms continually adapt to their environments, and the diversity of environments that exists promotes a diversity of organisms adapted to them.Maintaining high genetic diversity allows species to adapt to future environmental changes and avoid inbreeding.
