I have a question regarding choice D of question 3
Last sentence: Keystone status depends on context (geography, community diveristy, length of interaction)
D said that "As a keystone species of bee becomes more abundant it has a larger effect on the ecosystem it inhabits"
Meanwhile, length of interaction indicates that newly arrived species in particular may dramatically affect ecosystem
Doesn't "keystone species of bee becomes more abundant" is the same as "new bees arrived"?
