Why does high biodiversity help to make an ecosystem more stable?
It increases the number of individual organisms in every population of the ecosystem
It increases the amount of food that each species can obtain from the producers present
It reduces the competition between organisms of the same species for mates and territory
It reduces the dependence of one species on another for food, shelter and the environment
