Which zone experiences immersion and exposure due to tides?

• A. Random Distribution
• B. Population Density
• C. Intertidal Zone
• D. Mutualism

Answer: (C)

Immersion and exposure due to tides define the area where organisms must cope with alternating submerged and air-exposed conditions. The intertidal zone sits between the high- and low-tide marks, so it’s underwater during high tide and dry at low tide. This cycle creates a habitat where creatures must tolerate changes in moisture, salinity, and temperature, and many have adaptations to cling to rocks or retain moisture. The other options aren’t habitats described by tidal immersion and exposure: random distribution and population density refer to patterns and numbers of organisms, while mutualism is a type of ecological interaction.
