Which of the following statements is true about the food chain below? grass ⇒ grasshopper ⇒ bird ⇒ hawk the amount of energy transferred from the grass to the grasshopper is the amount of energy transferred from the grasshopper to the bird.
a)more than
b)less than
c)the same as

Option (C) is the correct answer.

Explanation:

In the given case, the amount of energy transferred from the grass to the grasshopper is more, because in each stage of the food chain, some energy is lost in the form of heat. The transfer of energy becomes more inefficient the more you climb up in the food chain.

Thus, we can conclude that the amount of energy transferred from the grass to the grasshopper is more than the amount of energy transferred from the grasshopper to the bird.

50.23 i believe is correct but don't quote me on that.

on passing the small ampere of electric current through the tube made of ar and hg of cfl generates uv rays which excites the fluorescent and thus emits the high radiation by consumption of just 5- 12 w in comparison to incandescent light which requires more power such as around 40 - 55 w to lighten.

moreover the life span of fluorescent or cfl is around 8000 h whereas the life span of incandescent is around 1200 h

hence, the building installed with incandescent lights bears more electricity bill.
