Are rocky shores high biodiversity?

Rocky shores are home to some of the most biologically diverse and productive communities throughout the world. These ecosystems lie at the interface between the land and the sea, exposing organisms here to alternating terrestrial and marine habitats in rhythm with the tidal cycle.

Do rocky shores have high biodiversity?

Rocky shores are biologically rich environments. Species here have become adapted to deal with the extreme conditions created by the movement of the tides and many cannot be found anywhere else.

Which has more biodiversity rocky or sandy shores?

Why do Sandy Shores have lower biodiversity than rocky shores. -Sandy shores are unstable due to the surface, as the fine mineral particles are easily moved by winds and tides; however, rocky shores are very stable and are able to support a multiple variety of marine organisms.

What type of shore has the lowest biodiversity?

Why is the rocky shore an extreme environment?

Because of the permanent action of tides and waves, it is characterized by erosional features. Together with the wind, sunlight and other physical factors it creates a complex environment, see Rocky shore morphology. Organisms that live in this area experience large daily fluctuations in their environment.

What is rocky beach?

Rocky beaches occur where coastal cliffs erode and crumble into large rock deposits along the the shoreline, blocking the build up of smaller, sandy sediment. Rocky beaches are areas of rich intertidal biodiversity.

What is the difference between rocky and sandy shores?

Rocky shores are a strong contrast with sandy beaches. On sandy shores, the substrate is shifting and unstable. … Physical conditions are relatively uniform because waves shape the substrate. On rocky shores, by contrast, the physical substrate is by definition hard and stable.
