What is the intertidal zone?

Back

The intertidal zone is the area of the shoreline that is exposed to air at low tide and submerged at high tide, experiencing extreme fluctuations in temperature and salinity.

Explain the concept of energy transfer in an ecosystem.

Back

Energy transfer in an ecosystem occurs when one organism consumes another, with only a fraction of the energy being passed on to the next trophic level.

What adaptations do organisms in the intertidal zone have?

Back

Organisms in the intertidal zone have adaptations such as strong attachment mechanisms, ability to tolerate desiccation, and specialized breathing structures.
