Accumulation of any substances in the air in the sufficient concentration to effect man, animals, vegetation or other materials is called air pollution.
Water pollution is defined as the presence of various types of impurities that tends to degrade its quality and either constitutes a health hazard or otherwise decrease the utility of water.
Sources of water pollution
Natural: Soil erosion, solutions of mineral in water, rain water, storms, earthquake. seawater intrusion, dust/dirt falling from atmosphere, deposition of animal wastes and fallen leaves, etc.
Man made: Due to agriculture, sewage, wastes, industry
Mitigation measures of water pollution
- Treatment of sewage
- Treatment of industrial waste
- Providing training and technical facilities in industry to treat waste water
- Not using water source for discharging sewage
- Rules and regulations for controlling pollution
- Proper planning of towns

An ecosystem is a community of living organisms in conjunction with the non-living components of their environment (things like air, wider and mineral soil), interacting as a system. Ecosystem is a natural unit which consists of biotic communities and their abiotic environment. It is also Basic functional unit in ecology. Energy, water, nitrogen and soil minerals are other essential abiotic components of an ecosystem. Ecosystem are controlled both by external and internal factors. External factors such as climate, parent material that forms the soil, typography, etc. and internal factors include disturbance, succession and the types of species present.
Characteristics of Ecosystem:
i) Biotic component: producer (green plants), consumers (animals), decomposers (microorganisms)
ii) Abiotic component: Air, water, soil
iii) Energy flow: Sun is the main source of energy
iv) Matter
v) Interrelationship
vi) Biological integration
vii) Flexibility
viii) Ecological regulation
ix) Smallest unit of biosphere
x) An open system with a continuous, but variable influx and loss of materials and energy.
