Which of the following best explains why some species in the intertidal zone are mobile?

Mobility allows them to produce more offspring through asexual reproduction.
B
Mobility allows them to avoid desiccation and predation during changing tides.
C
Mobility enables them to photosynthesize more efficiently.
D
Mobility increases their ability to anchor permanently to rocks.
Verified step by step guidance1
Understand the intertidal zone: The intertidal zone is the area between high and low tide. Organisms here face challenges such as exposure to air (desiccation), predation, and changing environmental conditions.
Analyze the role of mobility: Mobility in organisms allows them to move to more favorable conditions, such as finding moist areas to avoid drying out (desiccation) or escaping predators during low tide.
Evaluate the options: Consider each option in the context of the intertidal zone. For example, asexual reproduction is not directly linked to mobility, photosynthesis is a process for plants and algae (not typically mobile), and anchoring to rocks is the opposite of mobility.
Focus on the correct explanation: Mobility is most beneficial for avoiding desiccation and predation, as it allows organisms to adapt to the rapidly changing conditions of the intertidal zone.
Conclude: The correct explanation is that mobility allows organisms in the intertidal zone to avoid desiccation and predation during changing tides.
