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 __________ analyse for their experiment.

Read the passage again and answer the following questions.
1. What percentage of the earth’s surface is covered by seas and oceans?
75 % of the earth’s surface.
2. How do scientists now overcome the challenges of the depth?
By using modern devices.
3. What can submarines do to help scientists know about the undersea world?
They 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?
We can know a wide range of information, including water temperature, depth and the undersea populations.
5. What are the three groups of marine plants and animals?
They are those that live on or depend on the bottom like the starfish, those that move independently of water currents and those that are carried along by the currents.
6. What would happen if the sea biodiversity were not maintained?
Marine life would be at stake if the sea biodiversity were not maintained.
