Correct Answer: A) can see near objects clearly

Explanation

This question is asking about myopia, a condition that affects vision. The question is asking what people with myopia can or cannot see clearly. Myopia is also known as nearsightedness. It is a condition where a person can see objects that are close to them clearly, but objects that are far away appear blurry and out of focus. This means that Option A, which states that people with myopia can see near objects clearly, is the correct answer. In contrast, Option B states that people with myopia can see far away objects clearly. This is incorrect as myopia causes difficulty in seeing distant objects. Option C states that people with myopia cannot see any object clearly. This is also incorrect as people with myopia can see objects that are close to them clearly. Option D states that people with myopia are colourblind. This is not related to myopia and is therefore incorrect. To summarize, people with myopia can see near objects clearly but have difficulty seeing objects that are far away.

(a)Conservation: Conservation is the protection/preservation/restoration, and wise management/use of natural resources. Planning and management of resources from loss/waste/harm in order to achieve continuous use/ Sustainable quality of living for mankind OR Conservation is the wise/judicious/intelligent use of our natural resources to ensure their availability, and preserve the quality of the environment.

(ii) Endangered species:Are organisms that have become depleted/rare. Due to human activity/natural disaster/epidemic. Those habitats have become so disturbed. That they may be lost forever/become extinct.

(b)(i)Necessity to conserve forests: Economic importance:

Forests produce timber for the construction industry/buildings/furniture/boats/paper.

Domestic: Firewood for charcoal, medicines, gum/resins/rubber/tannins/chemicals/turpentine.

Biological importance: Provide food/ shelter for many animals, reduce wind erosion/desertification, serves as wind breaks/checking strong winds, cause precipitation of water from damp air/can increase amount of rainfall in an area, protect source of streams/rivers, help in maintaining CO\(_2\) / O\(_2\) balance in the atmosphere/the plants remove CO\(_2\) for photosynthesis/supply 0\(_2\) /purifies the atmosphere.

Educational: For ecological studies, to prevent certain species from getting extinct. Recreational/ Tourism: Serve as tourist attraction.

(ii) Methods for the conservation of forests:Regulations made to control excessive deforestation, only mature trees should be felled. Planting new forest trees/afforestation where they have been completely destroyed. Discouraging extensive use of natural forests as a source of timber since animals and some other plants are also destroyed/displaced. Replacing harvested/felled mature trees by seedlings in plantations! reforestation. Prevention of forest fires. Controlling plant diseases by using pesticides/chemicals to kill pests. Using trained forest rangers/guards to guard the forests against intruders/fight fires. Educating the local population on the dangers of deforestation/carrying out awareness campaigns against deforestation. Establishment of forest reserve.

(c)(i)Importance of decomposers in the ecosystem: They break down organic materials that are difficult for organisms to digest, they return organic matter to the environment in an inorganic form, so that they can be re-assimilated by plants/recycling nutrients.

(ii)Plant decomposers: Fungi, Rhizopus, Bacteria. Animal decomposers: Earthworms, Termites.
