What ecosystems affect biodiversity?

Which species has most diversity?

Among animals, insects are the most rich in species diversity, making up more than 70% of the total.

Which ecosystem most likely has the greatest biological diversity and therefore the highest sustainability?

What are some examples of species diversity?

So, some examples may include the presence of four or five different species of tree in a woodland forest, or perhaps 100 different species of fish, crustaceans and coral in a certain reef.
