Q1.8. continuing your studies, you perform a transplant experiment. you chisel up multiple rocks from the upper intertidal zone, each holding 10 individuals of species a, and move them to the lower intertidal zone among individuals of species c. you count the number of individuals of all species on the rocks every day for 30 days. based on your findings, what can you conclude? (remember that all 3 species settle in this zone at equal rates.)
