Answer 1

Hey dude here is ur answer...


Pollution is the introduction of harmful and toxic chemical substances in the natural environment. It can be naturally occurring contaminants or foreign substances. With industrialization and growth in population there has been increase in pollution in the atmosphere. The air, water and soil have been severely polluted by human activities. Our ecosystem is affected by pollution in number of ways.

Effects of Pollution on Ecosystem

Ecosystem is the natural system made of diverse species in its physical environment. The natural ecosystem is highly diverse and complex in nature. The toxic chemicals in the atmosphere spread widely throughout the ecosystem. It affects the soil, plants and other organisms, both directly and indirectly.

Ozone hinders the process of photosynthesis in plant species. Ozone gets dissolved in plants and reacts with chemicals that cause number of problems. The process of photosynthesis slows down which results in slower plant growth. The primary ecosystem function such as plant growth and biogeochemical cycling is affected by contaminants in the natural environment which affects the ecosystem services.

Ecosystem refers to the interaction between various organisms, plants, animals, fungi and bacteria. They form the entire food web where each depends on the one below it in the food chain. When the ecosystem gets polluted the natural balance in the ecosystem gets disrupted which effects different organisms in different ways. The pollutants like oil, nitrogen, detergents and phosphate can have negative impact on ecosystem especially if the water gets polluted. It can damage the ecological balance by adversely affecting the marine life. Thus, pollution hinders the natural cycle of ecosystem.

Hope this helps you...
