Which of the two ecosystem has more stable biodiversity?

Two of the Most Diverse Ecosystems on Earth

Species richness is greatest in tropical ecosystems. Tropical rain forests on land and coral reefs in marine systems are among the most biologically diverse ecosystems on Earth and have become the focus of popular attention.

Why are complex ecosystems more stable?

The reason greater stability is found in complex ecosystems is that with more complex interactions, the ability of organisms to deal with disturbances increases. … A food web depicts various ways in which organisms eat other organisms and obtain energy for their survival.

What keeps ecosystem stable?
