Their migration may be postponed if fog, clouds or rain hides the star.

  Read the following passage mark letter A, B, C, or D on your sheet to indicate the correct answer to each of  the questions
         Coincident with concerns about the accelerating loss of species and habitats has been a growing appreciation of the importance of  biological diversity, the number of species in a particular ecosystem, to the health of the Earth and human well-being. Much has been written about the diversity of terrestrial organisms, particularly the exceptionally rich life associated tropical rain-forest habitats. Relatively little has been said, however,  about diversity of life in the sea even though coral reef systems are comparable to rain forests in terms of richness of life.          An alien exploring Earth  would probably give priority to the planet's dominants - most distinctive feature - the ocean. Humans have a bias toward land that sometimes get in the way of truly examining global issues. Seen from far away, it is easy to realize landmasses occupy only one-third of the Earth’s surface. Given that two thirds of the Earth's surface is water and that marine life lives at all levels of the ocean, the total three-dimensional living space of the ocean is perhaps 100 times greater than that of land and contains more than 90 percent of all life on Earth even though the ocean has fewer distinct species.          The fact that half of the known species are thought to inhabit the world's rain forests doesn't seem surprising, considering the huge numbers of  insects that comprise the bulk of  the species. One scientist found many different species of ants  in just one tree from a rain forest. While every species is different from every other species, their genetic makeup constrains them to be insects and to share similar characteristics with 750,000 species of insects. If basic, broad categories such as phyla and classes are given more emphasis than differentiating between species, then the greatest diversity of  life is unquestionably by sea. Nearly every major type of plant and animal has some presentation there.   To appreciate fully the diversity and abundance of life in the sea, it helps to think small. Every spoonful of ocean water life, on the order of 100 to 100,000 bacteria cells plus assorted microscopic plants and animals, including larvae of organisms ranging from sponges and corals to starfish and clams and much more.
Which of the following conclusions is supported by the passage?
A.Ocean life is highly adaptive 
B.More attention needs to be paid to preserving ocean species and habitats 
C.Ocean life is primarily composed of plants 
D.The sea is highly resistant to the damage done by pollutants
