(c) Reddish brown colour disappears
(d) No change
Q19- Read the following and answer any four questions from 19(i) to 19(v)
Green plants capture 1% of the total incident sunlight and convert it into food energy. Only 10% of this energy is
transferred to the next trophic level. The remaining 90% of energy is consumed in life processes like digestion,
respiration, growth, reproduction by each trophic level. The energy left beyond 3-5 trophic level is so less that
none of the food chains could go beyond. Flow of energy in an ecosystem is unidirectional. As energy flows from
lower to upper trophic level, no energy is available for previous level. It flows from producer into consumer and
not vice-versa. Sun is the universal source of energy for all.
AHHH
(1) How much of the net primary productivity of a terrestrial ecosystem is eaten and digested by herbivores?
(a) 100%
(b) 10%
(c) 1%
(d) 0:15
(II) In an ecosystem, 10% of energy available for transfer from one trophic level to the next is in the form of:
(a) heat energy
(b) chemical energy
(d) mechanical energy (d) light energy
(1) In the given food chain, suppose the amount of energy at fourth trophic level is 5 kJ, what will be the energy
available at producer level?
Grass----> Grasshopper---> Frog---
---> Snake_ Hawk
(a) 5 kJ (6) 50 kJ (c) 500 kJ (d) 5000 J
(lv) In the following food chain, 20,000 J of energy was available to the plants. How much energy will be
available to man in this chain?
Plants----> Sheep-> Man
(a) 100 (b) 300 (c) 400) (d) 200
(v) Consider the following food chain which occurs in a forest:
Grass > Deer-> Lion
If 10000 Jof solar energy is available to grass, how much energy would be available to deer to transfer to lion.​
