Biodiversity / baiaudaiv əis əti/(noun)[U] the existence of a large number of different kinds of animals and plants which make a balanced environment
TASK 1:
THE WORDS IN THE BOX ALL APPEAR IN THE PASSAGE . FILL EACH BLANK WITH A SUITABLE WORD.

Gulf oversized biodiversity challenges
investigate tiny samples provide
Some plants and animals are referred to as_________________ organisms because they are extremely small.
Thanks to modern technology, scientists have been able to__________________ the life of plants and animals that live under the sea.
A_____________is a large area of sea that is partly surrounded by land.
_________________is a term that refers to the existence of different kinds of animals and plants which make a balanced environment.
These scientists have collected different _________________to analyse for their experiment.

Task 2 : Read the passage again and then answer the following question

What percentage of the earth’s surface is covered by seas and oceans?
How do scientists now overcome the challenges of the depth?
What can submarines do to help scientists know about the undersea world?
What can we learn from satellite photos?
What are the three groups of marine plants and animals?
What would happen if the sea biodiversity were not maintained?
Answer:
1.What percentage of the earth’s surface is covered by seas and oceans?

2.How do scientists now overcome the challenges of the depth?

3.What can submarines do to help scientists know about the undersea world?

Seas and oceans cover 75% percent of the earth’s surface.
Scientists now overcome the challenges of the depth using modern devices.
Submarines can investigate the seabed and bring samples of marine life back to the surface for further study.
4. What can we learn from the satellite photos?


5. What are the three groups of marine plants and animals?



6. What would happen if the sea biodiversity were not maintained?
Satellite photographs provide a wide range of information, including water temperature,depth and the undersea populations.
Three groups of marine plants and animals: plants and animals live or depend on the bottom like starfish, some are swimming animals such as fishes and sharks, others are tiny organisms that are carried along by the currents like the jellyfish.
If the sea biodiversity were not maintained, marine life would be at stake
