BIOXII14: ECOSYSTEM

Which of the following statements about food chains and energy flow through ecosystem is false?
1 A single organism can feed at several trophic levels
2 Detritivores feed at all trophic levels except the producer level.
3 The lower the trophic level at which an organism feeds, the more energy available
4 Those who are not producers are called heterotrophs.
Explanation:
Detritivores feed at all trophic levels except the producer level.this is the wrong statement, as detritivores feed on dead and decaying material belonging to producers and consumers.

An inverted pyramid of biomass can be found in which ecosystem?
1 Forest
2 Marine
3 Grass land
4 Tundra
Explanation:
An inverted pyramid of biomass can be found in marine ecosystem, because the size of fish is much bigger than phytoplankton.

Statement A : Energy pyramid is sloping. Statement B : The energy flow of one trophic level is lower than preceding trophic level.
1 Statement A is correct but Statement B is incorrect.
2 Statement A is incorrect but Statement B is correct.
3 Both statements are correct.
4 Both Statements are incorrect.
Explanation:
Both statements are correct.

Pyramid of energy is always upright which indicates that
1 Producers have lowest energy conversion efficiency
2 Energy conversion efficiency is same for all trophic levels.
3 Herbivores have better energy conversion efficiency than carnivores.
4 Carnivores have better efficiency than herbivores
Explanation:
Pyramid of energy is always upright indicates that herbivore is consumed by a carnivore. Here herbivore is primary consumer and carnivore is the secondary consumer. As energy passes into higher trophic levels along with food, its amount decreases because of its dissipation as heat and use in overcoming entropy as well as for performing various body activities
