The document discusses the intertidal zone, which is the area between high and low tide lines that is alternately submerged in water and exposed to air. It notes that the intertidal zone hosts a variety of sea life, including sea stars, snails, seaweed and crabs. It then provides more details on the different zones within the intertidal area and the types of habitats and organisms found in each, as well as how organisms are adapted to the conditions and interact with each other and their environment in the intertidal zone.

Is a rocky shorelines host
sea stars, snails, seaweed,
algae, and crabs.

two?

14. The intertidal zone, also known as
the foreshore and seashore and
sometimes referred to as the littoral
zone, is the area that is above water
at low tide and under water at high
tide (in other words, the area
between tide marks).

15. This area can include many different types
of habitats, with many types of animals,
such as starfish, sea urchins, and numerous
species of coral. The well-known area also
includes steep rocky cliffs, sandy beaches,
or wetlands (e.g., vast mudflats).

16. The defining characteristic of the
intertidal zone is that it is
submerged with water during high
tide and exposed to the air during
low tide. The zone can take many
forms, from sandy beaches to rocky
cliffs.

17. A typical rocky shore can be divided into a
spray zone or splash zone (also known as
the supratidal zone), which is above the
spring high-tide line and is covered by
water only during storms, and an intertidal
zone, which lies between the high and low
tidal extremes.

18. Along most shores, the intertidal zone can
be clearly separated into the following
subzones: high tide zone, middle tide zone,
and low tide zone. The intertidal zone is one
of a number of marine biomes or habitats,
including estuaries, neritic, surface and deep
zones.

20. Read each question carefully and encircle the letter of
the correct answer.
1.Organisms that live in the intertidal zone are adapted to
crashing waves and tidal changes. How do barnacles prevent
being washed away?
A. They cling tightly to rocks
B. Barnacles go with the waves
C. They open their shells
D. They store much salt in their bodies

21. 2.How do organisms exposed to air be able to
prevent drying out?
A. They seal completely their shells
B. They move up to zones that have plenty of
water
C. Organism feed on other organisms that are
watery
D. Organism store much water in their bodies

22. 3.Why do you think there are organisms that can
be found in more than one zone?
A. They are able to reproduce more of their kind
B. They are more adapted to the conditions in
the zone
C. They cannot adjust to harsh environment
D. They require little amount of water

23. 4.What factors may affect the salinity of water
across the Intertidal zone?
A. Amount of rainfall and evaporation
B. Kinds of organisms living in the area
C. Availability of space and food
D. Runoff from the people living along the shoreline

24. 5.In many desert regions, water is diverted from
streams and rivers to people in cities. How does this
affect the animals in the area?
A. The animals become more active in daylight hours
B. The animals migrate to tropical rainforests
C. The animals move closer to others to get food
D. The animals stop searching for food and water
