Question

Why are keystone species important?

Answer 1

Keystone species have a strong influence on community structure despite their low abundance. Their removal seriously disrupts the community.

• Fig trees in tropical rainforests provide fruit during scarcity, feeding monkeys, birds and bats.
• Beavers build dams and create ponds, forming new habitats for other species.
• Flying foxes pollinate plants and disperse seeds on tropical islands.
