Final answer:
The intertidal zone is a variable area between high and low tide where organisms face fluctuating temperatures and exposure, requiring adaptations for both wet and dry conditions, and the zone has plenty of nutrients and sunlight.
Step-by-step explanation:
The conditions in the intertidal zone are best described by a highly dynamic environment that presents unique challenges and opportunities for the organisms that inhabit it. The zone is characterized by regular exposure to air and sunlight during low tide and being submerged underwater at high tide. This fluctuating environment means the zone experiences variable temperatures, and inhabitants must be adapted to both wet and dry conditions. With the constant motion of the waves, few plants and algae can establish themselves, while the organisms present, such as shoreline crustaceans with tough exoskeletons, are adapted to protect themselves from desiccation and wave damage. Thus, the intertidal zone has an abundant supply of nutrients and sunlight, which are critical for the diverse life forms that have adapted to these conditions.
