As you may know, the 10% rule is applied here to calculate the energy levels on each tropic level. This rule states that the organism(s) use up 90% of the energy and pass on only 10% to the next tropic level.
The order we are going to calculate the energies on each level is this:
Pollution can be found in greater amounts at higher trophic levels compared to lower trophic levels by Biomagnification. It indicates the presence or increase in the concentration of toxic materials or pollutants in the tissues of living organisms in a trophic level of an eco system.
The answer is b. Our body is made up of water and so we need to refresh our body from time to time by bringing more water in. The water in the air also helps us get oxygen. Plants take the water and sunlight to do photosynthesis which creates oxygen so we can breathe
