NEET BIOLOGY

Detailed explanation-1: -A greater variety of life forms or biodiversity maintains the natural sustainability of all the living organisms present in the ecosystem. A large number of species ensures that the natural processes are carried out properly and the impact of any external stress is less.

Detailed explanation-2: -Greater biodiversity in ecosystems, species, and individuals leads to greater stability. For example, species with high genetic diversity and many populations that are adapted to a wide variety of conditions are more likely to be able to weather disturbances, disease, and climate change.

Detailed explanation-3: -Several factors contribute to species diversity, including habitat diversity, competition among species, and genetic diversity. Genetic diversity within a species not only is necessary to maintain diversity among species, 6 but also contributes to the diversity of food, fiber, and medicines available from nature.

Detailed explanation-4: -If a lake has many different types of fish and other marine life like turtles and frogs and many different types of plants and insects, then there is a great biodiversity of genes and species all contributing to the sustainability of the ecosystem of the lake.
