The population number of a keystone species begins to decline. It declines so that the population is only 10% of its original size. How will this affect the biodiversity of the area O The decline of the keystone species will affect the entire ecosystem. If the population of the keystone species shrinks, then the biodiversity of the area decreases. O When a keystone species' numbers decrease, only the producer level in the ecosystem will decline, so biodiversity will decrease, but only slightly. O Keystone species are usually at the top of the food chain; if their numbers decline, the levels below them will change. Due to the decline in the current keystone species, another organism will take its place and become a new keystone species; therefore, biodiversity will remain unchanged.
