Observe the dilemma of the fungus: it is a plant, but it possesses no chlorophyl. While all other plants put the sun’s energy to work for them combining the nutrients of ground and air into body structure, the chlorophylless fungus must look elsewhere for an energy supply. It finds it in those other plants which, having received their energy free from the sun, relinquish it at some point in their cycle either to other animals (like us humans) or to fungi.
In this search for energy the fungus has become the earth’ s major source of rot and decay. Wherever you see mold forming on a piece of bread, or a pile of leaves turning to compost, or a blown-down tree becoming pulp on the ground, you are watching a fungus eating. Without fungus action the earth would be piled high with the dead plant life of past centuries. In fact, certain plants which contain resins that are toxic to fungi will last indefinitely. Specimens of the redwood, for instance, can still be found resting on the forest floor centuries after having been blown down. [br] The author implies that fungi ______.
选项
A、are responsible for all the world’s rot and decay
B、cannot live completely apart from other plants
C、attack plants in order to kill them
D、are poisonous to resin-producing plants
答案
B
解析
作者暗示真菌类植物离开其他植物不能够完全存活。作者在第一段说,所有其他的植物让太阳的能量为它们服务,将泥土和空气中的营养成分化合,进入植物的体内,没有叶绿素的真菌类植物必须到别的地方寻求能量的供应。真菌类植物在其他的植物那里找到能量。
