List the zones that comprise rocky shores. Which of the zones would you expect to have the highest species diversity and which would have the lowest species diversity? Explain your answer
What will be an ideal response?
The three zones of rocky shores are the splash zone, the intertidal zone, and the subtidal zone. Species diversity is highest in the subtidal zone as a result of the greater stability of this zone. Animals are nearly always submerged in the subtidal, which means they will always have oxygen and food. Wave action in the subtidal is also reduced. The ultimate result is that more species can occupy this area without suffering as they would in the upper reaches of the intertidal.

Salamanders are amphibians with very interesting mating rituals. The males perform speciesspecific dances that attract females to mate
Male salamanders deposit spermatophores (mucus packets filled with sperm) on leaves, twigs, or the ground and guide females over them so females can take them up into their cloaca. Mating dances like this result in internal fertilization in many salamander species. Which of the following statements best explains why salamanders are not entirely terrestrial in spite of exhibiting internal fertilization in many species? A. Salamanders require water for gas exchange B. Salamanders simply lay their eggs near the water in which they live. C. Internal fertilization is the first necessary step towards non-dependence of water for reproduction. D. Salamanders do not produce amniotic eggs, therefore they require water for reproduction because eggs need protection from desiccation. E. Internal fertilization only occurs in species where reproduction does not require water. Salamanders simply lay their eggs near the water in which they live.
