Use the accompanying figure to answer this question: What factors have a positive effect on plant biomass, based on the data presented?

In the following figure, the isthmus separates the Pacific Ocean on the left (side A) from the Caribbean (Atlantic Ocean) on the right (side B). The seawater on either side of the isthmus is separated into five depth habitats (15), with 1 being the shallowest.Why should deepwater shrimp on different sides of the isthmus have diverged from each other earlier than shallow-water shrimp?
