Two species of sea urchins adapted to live side by side on the sandy bottom of the sea floor. The two species appear to have the
same diet—drift seaweeds and other bits of organic matter. They are able to adapt and to live in the same environment without competing with each other. How are they able to share habitat and food resources?
They could adapt to live together so that for example one starts eating only seaweed while the other starts eating only organic matter so they don't compete for food. They could also adapt like when squirrels are separated into those who eat on trees and those who eat on the ground. The 2 urchin types could split into those who eat of the ground and those that eat what floats and drifts.
I believe the plates are called the south American plates just saying I might be correct or I might be wrong so don't take my word for it I am not the expert
