Question

The following statement is true or false:

Only 10 per cent of the light energy given by the sun is available for transfer at each higher trophic level in a food chain.

True or False
Advertisements

Solution

False. 

Explanation:

Only about 1% of the solar energy falling on plants is captured by autotrophs (green plants) through photosynthesis. Of the energy stored at one trophic level, only about 10% is transferred to the next trophic level.

Therefore, 10% refers to the transfer of energy from one trophic level to the next, not to the solar energy received from the Sun.

Human body is made up of five important components, of which water is the main component. Food, as well as potable water, are essential for every human being. The food is obtained from plants through agriculture. Pesticides are being used extensively for a high yield in the fields. These pesticides are absorbed by the plants from the soil along with water and minerals and from the water bodies these pesticides are taken up by the aquatic animals and plants. As these chemicals are not biodegradables, they get accumulated progressively at each trophic level. The maximum concentration of these chemicals gets accumulated in our bodies and greatly affects the health of our mind and body.
