Question

Match the contents of columns I, II and III (double matching):

Column I	Column II	Column III
(a) Ecosystem	(i) Food Chain	p. Food energy
(b) Producers	(ii) Abiotic components	q. Biomagnification
(c) Omnivores	(iii) Transducer	r. Animal Food
(d) Persistent pesticide	(iv) Plant food	s. Biotic components

Accepted Answer

a-(ii)-s

The ecosystem consists of biotic or living and abiotic or non-living components. These components are linked together through nutrient cycles and energy flow.

(b)-(iii)-p

Producers are also known as transducers because they can convert solar energy into chemical energy in the form of food.

(c)-(iv)-r

Omnivores are those organisms which depend on both animals and plants for their nutrition. They are divided into sub-categories based on their feeding behaviours.

(d)-(i)-q

In the process of biomagnification, the pesticides get accumulated at each trophic level in the food chain. The degradation or excretion of these chemicals does not take place due to one of the main reasons being its water insolubility.
