In plants,which of the following explains their functions and characteristics?

The following is a graphical representation of organismic response. Identify $P, Q$,and $R$.
$P \quad\quad Q \quad\quad R$

Give one example for each of the following:
$(i)$ Eurythermal plant species: $................$.
$(ii)$ $A$ hot water spring organism: $................$.
$(iii)$ An organism seen in deep ocean trenches: $................$.
$(iv)$ An organism seen in a compost pit: $................$.
$(v)$ $A$ parasitic angiosperm: $................$.
$(vi)$ $A$ stenothermal plant species: $................$.
$(vii)$ Soil organism: $................$.
$(viii)$ $A$ benthic animal: $................$.
$(ix)$ Antifreeze compound seen in Antarctic fish: $................$.
$(x)$ An organism which can conform: $................$.

Explain about adaptation in detail.

Which rule states that mammals living in colder climates generally have shorter ears and limbs to minimize heat loss?

In a sea shore,the benthic animals live in sandy,muddy and rocky substrata and accordingly developed the following adaptations:
$(a)$ Burrowing
$(b)$ Building tubes

Match the suitable substratum against each adaptation.
