Read the passage and choose the letter A, B, C or D to indicate the correct answer to each of the questions.

1. Scattered through the seas of the world are billions of tons of small plants and animals called plankton. Most of these plants and animals are too small for the human eye to see.

‘ They drift about lazily with the currents, providing a basic food for many larger animals.

2.Plankton has been described as the equivalent of the grasses that grow on land. However, plankton is richer in food value than the land grasses. One scientist has estimated that while grasses of the world produce about 49 billion tons of valuable carbohydrates each year, the sea’s plankton generates more than twice as much.

3.Despite its enormous food potential, little effort was made until recently to farm plankton as we farm grasses on land. Now, marine scientists have begun to study this possibility to look for different means of feeding an expanding world population.

4.One type of plankton that seems to have great harvest possibilities is a tiny shrimp-like creature called krill. Growing to two or three inches long, krill provide the major food for the giant blue whale, the largest animal ever to inhabit the Earth. Krill swim about just below the surface in huge schools mainly in the cold Antarctic. Because of their pink colour, they often appear as a solid reddish mass when viewed from a ship or the air. Krill are very high in food value. A pound of krill contains about 460 calories. If the krill can feed such huge creatures as whales, many scientists reason, they must be certainly a new food source for humans.
