DDT is non- biodegradable chemical. Biomagnification is the phenomenon of increasing concentration of compound in the tissue of organism, as the compound passes up a food chain, usually as a result of food intake. In this case the concentration of compound will increase with increasing the tropic level.

Biomagnifying pollutant which increase in concentration from producers→ primary consumers→secondary consumers→ tertiary consumers → top consumers

The snake is a tertiary consumer. So the DDT concentration will high in snake

In other words, snakes are tertiary consumers and shows the highest concentration of DDT Grasshoppers and cattle occur in the same tropic level as primary consumers ,so DDT’s concentration is least. Toad is secondary consumer and shows medium concentration of DDT

The ozone hole is caused by the effect of pollutant in the atmosphere destroying stratospheric ozone. During the Antarctic winter something special happens to the Antarctic weather. Strong wind blowing around the continent form, this is known as the “polar Vortex” – this isolates the air over Antarctica from the rest of the world. Polar stratospheric clouds at about 80,000 feet altitude these are the highest flying of all clouds and only occur in the Polar Regions where the temperature in the upper atmosphere dips below minus 100F. They are sometime called “nacreous clouds” as they are coloured like the nacre of mother – of – pearl with coloured bands that move the position of cloud and observer. By the time spring arrives and the sun comes back after the long polar night, the ozone levels are severely depleted around the Antarctic continent causing the “ozone hole”. Unfortunately there then follows a particularly long period of high sunshine and long days, just to make effect of the ozone hole worse.

A carbon credit is a generic term for any tradable certificate or permit representing the right to emit one tonne of carbon dioxide or the mass of another greenhouse gas with a carbon dioxide. Carbon credits and carbon markets are a component of national and international attempts to mitigate the growth in consternation of green house gases (GHGs) one carbon credits is equal to one metric tonne of carbon dioxide, or in some markets , carbon dioxide equivalent gases . carbon trading approach the goal is to allow market mechanisms to drive industrial and commercial processes in the direction of low emission or less carbon intensive approaches than those used when there is no cost Emitting Carbon Dioxide and other GHGs into the atmosphere
