Mango,tuna fish,and snow leopards are:

Match the following columns:

Column-$I$ (Temperature)	Column-$II$ (Organism)
$P$. Above $100^{\circ}C$	$I$. Thermoacidophiles
$Q$. $37^{\circ}C$	$II$. Human
$R$. Below $0^{\circ}C$	$III$. Antarctic fish

Match the types of animals in Column-$I$ with their adaptations in Column-$II$:

Column-$I$	Column-$II$
$i$. Eurythermal	$a$. Can tolerate only a narrow range of salinity
$ii$. Stenothermal	$b$. Can tolerate a wide range of temperature
$iii$. Euryhaline	$c$. Can tolerate a wide range of salinity
$iv$. Stenohaline	$d$. Can tolerate only a narrow range of temperature

Which of the following is the most important abiotic factor in a pond ecosystem?

Organisms that can tolerate and thrive in a wide range of temperatures are $P$,while those restricted to a narrow range of temperatures are $Q$. Choose the correct option for $P$ and $Q$.
$P \quad\quad Q$
