• A. $A-\left(i\right),B-\left(v\right),C-\left(iv\right),D-\left(iii\right),E-\left(ii\right)$
• B. $A-\left(ii\right),B-\left(i\right),C-\left(v\right),D-\left(iv\right),E-\left(iii\right)$
• C. $A-\left(iii\right),B-\left(ii\right),C-\left(i\right),D-\left(v\right),E-\left(iv\right)$
• D. $A-\left(v\right),B-\left(iv\right),C-\left(i\right),D-\left(ii\right),E-\left(iii\right)$

Answer 1

The correct option is D $A-\left(v\right),B-\left(iv\right),C-\left(i\right),D-\left(ii\right),E-\left(iii\right)$

(i) Ticks on dogs- The ticks present on the dogs body are to suck blood which acts the source of nutrition for them in which the ticks act as a parasite while the dogs the hosts.hence it shows parasitism

(ii) Balanus and chathamalus- Balanus outcompetes chthamalus by crowding bt chthamalus occurs in the high tide levels were balanus cannot where both balanus and chthamalus are the species of barnacle. It shows competition within the species.

(iii) Sparrow and any seed- the sparrow or in that case any granivores whose preys are seed or grains preadte on plants thus leading to plant-animal interaction thus performing predatorship. It shows predation .

(iv) Epiphyte on mango branch- epiphyte are the plants which which grow on other plants leaving the host unaffected by its present here the epiphyte such as orchids grown on mango plant where it is neither harmed nor benefitted .It shows commensalism.

(v) Mycorrhiza- It is the association between the fungus and the roots of the vascular plants where both are benefited equally none of them is harmed.This is an example of mutualism or symbiotic association.

so the correct ans is ' D A-(v),B-(iv),C-(i),D-(ii),E-(iii)
