1.)How does the abundance and diversity of life change across the various intertidal zones? Life is very abundant and very diverse in the lower intertidal, and becomes less diverse towards the high intertidal. Both diversity and abundance are lowest in the spray zone.
2.)Describe how the physical stresses on life vary from the top of the intertidal zone to the bottom. At the top of the intertidal zone, organisms spend more time exposed than underwater, so they will have to cope with desiccation and large temperature swings.
3.)How are these stresses reflected in the types of animals that inhabit the intertidal subzones? ... The harsh conditions in the intertidal zone cut down on competition for food and for space by excluding many animals. And the shallow water transmits the sunlight for bottom-dwelling plants' need for photosynthesis.
4.)What are some of the benefits of intertidal living? The harsh conditions in the intertidal zone cut down on competition for food and for space by excluding many animals. And the shallow water transmits the sunlight for bottom-dwelling plants' need for photosynthesis.
