Tag: water and air and their importance

option  B sun is correct answer . as remaining is pollutating sources 

Renewable resources are those that are replenished naturally over relatively short periods of time. It includes solar energy, tidal energy, geothermal energy, biomass, etc. Thus the correct answer is option A.

Natural resources occur naturally within environments, that exist relatively undistributed by humanity, in a natural form. A natural resource is often characterized by amounts of biodiversity and geodiversity existent in various ecosystems. Natural resources are derived from the environment. Biotic resources are obtained from the biosphere (living and organic material), such as forests and animals, and the materials, that can be obtained from them. Forests and wildlife are both renewable in the short term but non renewable once a point has been reached or to a point. Forests can be managed to some degree sustainable forestry cuts older trees, while planting new one to replace them, this works in some types of environments better than others.

Isotope of oxygen is used to detect the reaction mechanism of formation of esters. 

During the process of photosynthesis, the hydrogen is combined with carbon atoms to produce oxygen which is then released into the atmosphere.

Oxygen is not present in graphite. It is am allotrope of carbon. 

Plant is necessary for animals for food and shelter,air is important for atmosphere and oxygen is important for breathing.

Plants consumes carbon dioxide and gives oxygen.
