B
a greater variety of species present allows more organisms to adapt after changes occur
C
the transition area between two ecosystems is narrower
D
there are fewer species to be affected by environmental stresses
Explanation: 

Detailed explanation-1: -The ecosystem that supports a sustainable life i.e. is able to meet the needs of the present population and the future population, without any assistance from outside the ecosystem is known as a sustainable ecosystem. A sustainable ecosystem is a self-sustaining system.

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.
