Role of metal and non metal in plants and animal?

Answer 1

Water is made available for mankind through the water cycle in which there is a continual exchange of water between the surface of the Earth and the atmosphere. The essential processes in the cycle are evaporation, condensation, transpiration, precipitation and runoff.

Nitrogen is made available to living systems through the process of fixation. This can occur in three ways: atmospheric fixation, industrial fixation and biological fixation.

The carbon cycle maintains the concentration of carbon dioxide in the air. This gas is taken in by plants and converted to organic compounds through the process of photosynthesis and is released by plants and animals through respiration.

Non-metals and living systems

1. Carbon dioxide and water are important elements in the process of photosynthesis. 6CO2(g) + 6H2O(l) === 6CO2(g) + 6H2O(l) + energy

3. Nitrogen and sulphur are important in protein synthesis, which is essential for growth and development of tissues.

4. Phosphorus is an important plant nutrient and helps to build strong bones and teeth.

5. Water, containing the elements hydrogen and oxygen, is a universal solvent, which is essential for many processes and reactions in living cells.

Non-metals and the environment

1. Ions of nitrogen, phosphorus and sulphur (NO3-, PO43- and SO42-) from untreated sewage, detergents and fertilisers can affect water bodies by causing nutrient enrichment which can lead to oxygen depletion and death of aquatic organisms.

2. Organic waste from sewage can affect aquatic organisms by depleting their oxygen supply.

3. Insecticides and herbicides can become toxic to animals and can become concentrated up the food chain.

4. Oxides of nitrogen, sulphur and carbon from the combustion of fuels can dissolve in rainwater, forming acid rain, which is harmful to plants and animals and can corrode buildings.

5. Chlorofluorocarbons (CFCs) from aerosols can break down the ozone layer, thereby allowing harmful UV-radiation to reach Earth, which can lead to skin cancers.

Metals and living systems

1. Magnesium and iron are important constituents of chlorophyll in green plants. Iron forms part of the haemoglobin molecule found in red blood cells.

2. Calcium is essential for the formation of healthy teeth and bones.

3. Ions of sodium and potassium are needed for the transmission of nerve impulses.

4. Zinc, copper, manganese and cobalt are examples of trace elements needed by plants and animals for their proper growth and development.

Answer 2

my question in what the regarding the roll of metal in plants and animals

Answer 3

It depends on the element. You need to be more specific.
