  托福阅读句子简化题:Spartina

  【Paragraph 2】These natural salt marshes are among the most productive habitats in the marine environment. Nutrient-rich water is brought to the wetlands during each high tide, making a high rate of food production possible. As the seaweed and marsh grass leaves die, bacteria break down the plant material, and insects, small shrimplike organisms, fiddler crabs, and marsh snails eat the decaying plant tissue, digest it, and excrete wastes high in nutrients. Numerous insects occupy the marsh, feeding on living or dead cordgrass tissue, and redwing blackbirds, sparrows, rodents, rabbits, and deer feed directly on the cordgrass. Each tidal cycle carries plant material into the offshore water to be used by the subtidal organisms.(Spartina)

  Which of the sentences below best express the essential information in the highlighted sentence in the passage? Incorrect choices change the meaning in important ways or leave out essential information.

  ○ Insects feed only on dead cordgrass, while most other marsh inhabitants feed on live cordgrass.

  ○ The marsh is a good habitat for insects, but a relatively poor one for birds and animals.

  ○ Although cordgrass provides food for birds and animals, it gives insects both food and a place to live.

  ○ Cordgrass provides food for numerous insects, birds, and other animals
