Estuaries and Intertidal Zones

1. What do you call the semi-enclosed area where fresh water from a river meets salty water from the sea.

• A. Watershed

• B. Groundwater

• C. Estuary

• D. Ocean

2. It is a factor of living organisms that can affect Ecosystem.

• A. Biotic

• B. bar-built

• C. Abiotic

• D. fjords

3. It is a geographic area where plants, animals, and other organisms, as well as weather and landscape, work together to form a bubble of life.

• A. emersion

• B. Zone

• C. Intertidal

• D. Ecosystem

4. Occur in the intertidal zone between the land and the sea and that are covered by salty or brackish water for at least part of the time.

• A. Rocky shore

• B. Mud Flats

• C. Coral Reefs

• D. Salt Marsh

5. It is located along the edges of the salt marsh. This harsh habitat is covered by water at flood high tide and exposed to the scorching sun at ebb (low) tide. It consists of a soggy substrate made up of clay and silt that is deposited during slack tide.

• A. Rocky shore

• B. Mud Flats

• C. Coral Reefs

• D. Salt Marsh

8. It is an interlinked food chain. It consists of two or more chains and contains more organisms compared to a single food chain.

• A. Estuaries

• B. Intertidal

• C. Food Chain

• D. Food Web

9. It is a series of organisms in which an organism feeds on another organism and so on. It always starts with the producer.

• A. Estuaries

• B. Intertidal

• C. Food Chain

• D. Food Web

10. Interactions that take place in inertial zones and estuaries are___.

• A. Estuaries and Intertidal zone
