1 Questions are based on the following passage.
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( 生态系统., to the health of the Earth and human well-being. Much has been written about the diversity of terrestrial organisms ( 陆生生物., particularly the exceptionally rich life associated with 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 dominant, most distinctive feature-the ocean. Humans have a bias toward land that sometimes gets in the way of truly examining global issues. Seen from far away, it is easy to realize that land masses 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 does not 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, the 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( 门. and classes( 纲. are given more emphasis than differentiating between species, then the greatest diversity of life is unquestionably in the sea. Nearly every major type of plant and animal has some representation there.
To appreciate fully the diversity and abundance of life in the sea, it helps to think small. Every spoonful of ocean water contains life, on the order of 100 to 100,000 bacterial cells plus assorted microscopic (极小的. plant sand animals, including larvae( 幼虫. of organisms ranging from sponges and corals to starfish and clams( 蛤蜊.and much more.

C．the sea is even richer in life than the land
