Read the following and answer the questions:
Biosphere is a global ecosystem composed of living organisms and abiotic factors from which they derive energy and nutrients. An ecosystem is defined as a structural and functional unit of the biosphere consisting of living and non-living environments that interact by means of food chains and chemical cycles resulting in energy flow, biotic diversity and material cycling to form a stable, self-supporting system.
Biotic vs. Abiotic Factors
Q. Consider the following statements concerning food chains:
Which two of the above statements are correct?
(i) Removal of 80% tigers from an area resulted in greatly increased growth of vegetation
(ii) Removal of most of the carnivores resulted in an increased population of herbivores.
(iii) The length of the food chains is generally limited to 3 – 4 trophic levels due to energy loss
(iv) The length of the food chains may vary from 2 to 8 trophic levels
  • a)
    (i), (iv)
  • b)
    (i), (ii)
  • c)
    (ii), (iii)
  • d)
    (iii), (iv)

In a food chain, the carnivores eat up herbivores, or in other words, the secondary consumers consume the primary consumers. So, we can say that if the number of carnivores decreases, the number of herbivores like deer go on increasing as they will not get eaten up. So, the removal of most of the carnivores will result in an increased population of deer.
Apart from this, we also know that as we move from one trophic level to another, the amount of energy goes on decreasing. This is according to the 10% law according to which, at each trophic level, 10% energy is lost. So, each food chain is only 3-4 trophic levels long due to these energy losses.
Therefore, ii and iii are the correct statements.
