Answer:
1. An estuary is where a river meets the sea. Estuaries are transition zones from fresh
water to salt water. Nutrients from the mixture of fresh and salt water, abundant sunlight,
and shallow depths make estuaries very productive ecosystems. Estuaries are made up of many different types of habitats-oyster reefs, coral reefs,
rocky shores, marshes, and mangroves. There are different animals that live in each of
these different habitats. Fish, shellfish, and migratory birds are just a few of the animals
that can live in an estuary.
2. Intertidal zone is the area where ocean tides cover and uncover in a regular cycle.
Sometimes it is under water. Other times it is exposed to the Sun and air. It is underwater
at high tide and above the water at low tide. When the tide is low, the living things there
can be exposed to warmer temperatures and brighter light. At high tide, they can be
pounded by waves.
3. Why need to protect intertidal zones
Human activities disrupt the balance of the intertidal zone and can have long-term
adverse effects. Oil spill, for example, has toxic effect and lowers the fitness of local
organisms to survive and reproduce.
We need to conserve and protect for a number of important reasons.
- Animals and plants in intertidal zone are important food source for humans.
Humans harvest clams, oysters, mussels, and crabs for food.
- The intertidal zone serves as a buffer. It protects land from erosion by wave action
during storms. This protection is important for buildings, roads, bridges and other
infrastructure built along shorelines
- Animals such as bears, wolves, raccoons, mink, otter, and deer forage for different
marine life during low tide.
- During low tide, migrating and residents and many fishes on the shore birds feed
on the zone.
