[C] A convex lens of focal length 5 cm
For reading small letters, a convex lens of focal length 5 cm should be used. You must know two sentences in the context of this question. Such as
(1) Magnification is also higher for convex lenses having shorter focal length.
(2) A magnified image of an object will be obtained when it is placed between the optical centre and focus of a convex lens.
The energy from the sun reaches the food chain through the primary roducers (plants). This energy is passed on through successive trophic levels in the food chain. The energy transfer in the food chain follows the 10 percent law where in only 10% of the energy is transferred from one trophic level tRead more
The energy from the sun reaches the food chain through the primary roducers (plants). This energy is passed on through successive trophic levels in the food chain. The energy transfer in the food chain follows the 10 percent law where in only 10% of the energy is transferred from one trophic level to the next successively. So, the movement of energy is only in one direction from lower to higher trophic level.
In a food chain, only 10% of the total amount of energy is passed on to the next trophic level from the previous trophic level. So, there is a decrease in the amount of energy available at the successive trophic levels. As we move higher up in the food chain the amount of energy diminishes to a leveRead more
In a food chain, only 10% of the total amount of energy is passed on to the next trophic level from the previous trophic level. So, there is a decrease in the amount of energy available at the successive trophic levels. As we move higher up in the food chain the amount of energy diminishes to a level at which it cannot sustain any trophic level, thereby limiting the number of trophic levels.
