Which of the following statements is not correct?
(i) Forests protect the soil from erosion.
(ii) Plants and animals in a forest are not dependent on one another.
(iii) Forests influence the climate and water cycle.
(iv) Soil helps forests to grow and regenerate.
Correct answer: (ii) Plants and animals in a forest are not dependent on one another.
Explanation: Plants and animals in a forest are dependent on one another for food and the exchange of gases.
[Extra information: Forests are a very important renewable natural resource. The roots of trees in the forest bind the soil particles together which helps in preventing soil erosion.
Plants in the forest absorb water from the soil through their roots and release it into the air by the process of transpiration which increases the amount of water vapour in the air, helps in cloud formation and rainfall. Thus, forests play an important role in the water cycle operating on the earth. Moreover, the raindrops do not fall directly on the forest floor with full force due to the presence of plants in different layers in a forest which prevents flooding. Forests help in maintaining the water table by harvesting rainwater.
Decomposers are the organisms that feed on the dead bodies of plants and animals. They convert complex organic molecules present in dead and decay matter into simple inorganic molecules and allow them to mix with the soil. Thus, they help to recycle nutrients.
Some decomposers are bacteria, fungi, beetles and grubs.]
