4- they have an unusually uniform habitat

Answer 1

Step-by-step explanation:

1.What happens as the number of niches in an ecosystem goes up?:

• Biodiversity increases

- As the number of niches increases, I suppose there would be more competition for space

2.What group of organisms has the greatest number of species?

• insects

-In terms of numbers of species, insects certainly represent the largest percentage of the world's organisms. There are more than 1 million species of insects that have been documented and studied by scientists.

3.Why do coral reefs have such a high biodiversity?

• they have many different niches

-High biodiversity ensures the health of the reef. It spreads those roles across many species, so if one species is affected by a disease or other threat, that role won't be lost on the reef.
