A company wants to grow California mussels commercially in a bay on the coast. Sea stars are a predator of the California mussel, and act as a keystone species in the environment. The company wants to use divers to remove all sea stars that are found in the bay, so they will not eat the California mussels. Based on what you have learned, what do you think a computer simulation of removing all the sea stars from the mussel beds would show?

• Mussel populations will increase and the ecosystem will become more stable.

• Sea star populations might increase due to lack of predation, but the stability of the ecosystem might be threatened.

• Mussel populations will decrease and the stability of the ecosystem might be threatened.

• Mussel populations might increase due to lack of predation, but the stability of the ecosystem might be threatened.
