Question

Match the terms given in column I with the terms given in column II and column III having the same meaning:

	Column I	Column II	Column III
(i)	Secondary consumer	Herbivore	$1^{st}$ trophic level
(ii)	Primary consumer	Autotroph	$3^{rd}$ trophic level
(iii)	Producer	Carnivore	$4^{th}$ trophic level
(iv)	Tertiary consumer	Large carnivore	$2^{nd}$ trophic level

Give one example of a food chain having four organisms. Below each organism write the three appropriate terms from the part $(a)$ above which you think it represents.

(ii)	Primary consumer	Harbivore	$2^{nd}$ trophic level
(iii)	Producer	Autotrop	$1^{st}$ trophic level
(iv)	Tertiary consumer	Large carnivore	$4^{th}$ trophic level
