Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
The more diverse an ecosystem is-
A
the more threatened its populations are
B
the more similar the species will be
C
the more sustainable it is
D
the fewer varieties of species are present
Explanation: 

Detailed explanation-1: -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-2: -Biodiversity boosts ecosystem productivity where each species, no matter how small, all have an important role to play. For example, A larger number of plant species means a greater variety of crops. Greater species diversity ensures natural sustainability for all life forms.

Detailed explanation-3: -Diversity-Stability Theory Biologically diverse communities are also more likely to contain species that confer resilience to that ecosystem because as a community accumulates species, there is a higher chance of any one of them having traits that enable them to adapt to a changing environment.

Detailed explanation-4: -Ecosystem Diversity can be defined as the variety of different habitats, communities and ecological processes. A biological community is defined by the species that occupy a particular area and the interactions between those species.

Detailed explanation-5: -Ecosystem biodiversity refers to the variety of ecosystems, by their nature and number, where living species interact with their environment and with each other. For example, on Earth, there are different ecosystems, each with their specificities like deserts, oceans, lakes, plains or forests.
