(ii) Terrestrial plants take about 1% of the Sun’s

energy and change it to chemical energy.

(iii) A great amount of energy is lost as heat / used

for digestion / doing work / growth and reproduction.

(iv) Only 10% of organic matter is present at each

trophic level (and available to the next trophic

level).

(because of 10 percent law) .

(vi) The number of producers are maximum (the
