Both primary and secondary succession begin with pioneer species that....

A hurricane hit the coast and destroyed the habitat. When the environment grows back this shows-

• Primary succession

• Sustainability

• Secondary succession

• Biodiversity

The more diverse the ecosystem is-

• The more similar the species are

• The more threatened its population is

• the fewer varieties of species are present

• The more sustainable it is
