Many organisms live in intertidal areas. However, fewer organisms live on high, rocky shores than in other intertidal environment. What are the probable reason for this?
Answer:
The intertidal zone or area is defined as the area where the ocean and land meets between high and low tides.
Many of the organisms live in intertidal areas while fewer organisms live on high rocky shores because of the adaptation ability of the organisms.The probable reasons for this can be:
Intertidal zones have frequent changes in temperature, moisture, and salinity, some animals evolve them and migrate to rocky shores.Some animals include adaptive features such as attaching more firmly to the rocks along with resistant shells, restricting activities and the ability to retain water helps them to survive in rocky shores.Most of the animals are unable to withstand to the sun for most of the day as in rocky shores, so they prefer to live in intertidal zones.Animals living in rocky shores depends on the floating water that carry food for them.Example of animals living in intertidal zones are brittle stars, barnacles, crabs and other.
Example of animals living in rocky shores are sponges, mussels and sea squirts et-cetra.
Hence, the animals evolve some adaptive feature that allow them to migrate to rocky shores.
