Question

Prepare a pictorial chart/an album or a short power point presentation on any of one of the following topics. (i) Global warming (ii) Biomagnification (iii) Entrophication

Answer 1

(i) Global warming:

Greenhouse gases like water vapour, carbonmonoxide, and methane and ozone etc., are surrounded by earth and traps more heat and leads to an increases temperature of the earth.

If it increases, it will lead to the loss of human lives, plants, and animals.

(ii) Biomagnifications:

All things are part of a food chain.

As a result, toxins stored in the fats and oils of an organism at a trophic level are returned to the organisms at the next trophic level.

(iii) Eutrophication:

Degradation of water bodies from phosphorous and nitrogen through over fertilization, resulting in excess plant biomass, and consequently oxygen and habitat depletion.
