A forest ecosystem having a lot of green plants has some foxes, lions and rabbits in it.

(a) Write a food chain comprising all the four organisms mentioned above.

(b) Name

(ii) two carnivores, in this food chain.

(c) Name the link which is a predator as well as a prey.

(d) Name

(i) second trophic level, and

(ii) third trophic level.

(e) Which link of this food chain can feed on second trophic level as well as third trophic level, independently?

(f) If the sun provides 1000 J of energy to the plants, then how much energy will be transferred to fox through the food chain.

Answer :

a) Food Chain= Green plants- rabbits-fox-lions

b) i)Herbivore- Rabbit is a herbivore

ii) Carnivore- Fox and lion are carnivores.

c) Fox is a predator as well as a prey. It eats rabbits as well as gets eaten by lion

d) i) Second trophic level- Rabbits

ii) Third trophic level- Fox.

e) Lion can feed on rabbits (secondary trophic level) as well as Fox (third trophic level), because they are carnivores.

f) If 1000J of energy is provided by sun to plants, the plant will absorb only 1% of this energy to make food. 1% of 1000J = 10J. Further, applying the ten percent rule,

The rabbits will receive 10% of 10J i.e. 1J.

10% of 1J= 0.1 J will be passed on to the foxes,.
