Question 17
Match the organisms given in Column I with their mode of nutrition given in Column II.

$\begin{array}{cc}& \\ ColumnI& ColumnII\\ \left(a\right)Mangotree& \left(i\right)Insectivorousplant\\ \left(b\right)Mushroom& \left(ii\right)Heterotroph\\ \left(c\right)Pitcherplant& \left(iii\right)Autotroph\\ \left(d\right)Cuscuta& \left(iv\right)Saprophyte\\ \left(e\right)Elephant& \left(v\right)Parasitic\end{array}$

Answer 1

$\begin{array}{cc}& \\ ColumnI& ColumnII\\ \left(a\right)Mangotree& \left(iii\right)Autotroph\\ \left(b\right)Mushroom& \left(iv\right)Saprophyte\\ \left(c\right)Pitcherplant& \left(i\right)Insectivorousplant\\ \left(d\right)Cuscuta& \left(v\right)Parasitic\\ \left(e\right)Elephant& \left(ii\right)Heterotroph\end{array}$

(a) The autotrophs are the organisms which can prepare food themselves through the process known as photosynthesis. Example: Mango tree

(b) The plants which derive nutrition from dead and decaying organisms are called saprotrophs or saprophytes. Example: Mushroom

(c) The plants which derive nutrients from insects by trapping and digesting them. Such insect-eating plants are called insectivorous plants. Example: Pitcher plant

(d) The organisms that derive nutrition from the body of other living organisms (host) are called parasites. Example: Cuscuta

(e) The organisms that take in ready-made food prepared by the plants are called heterotrophs. Example: Elephant
