Competition for light, nutrients and space is most severe between

Camouflage is an important mechanism where

The following graph depicts changes in two populations ($A$ and $B$) of herbivores in a grassy field. $A$ possible reason for these changes is that

American lakes visiting flamingoes and resident fishes compete for their common food $A$ in the lake. Resources $B$ limiting for competition to occur; in interference competition,the feeding efficiency of one species might be $C$ due to the interfering and inhibitory presence of the other species,even if resources (food and space) are abundant. Choose the correct option for $A$,$B$,and $C$.

Given below are two statements $:$
Statement-$I$ : Species facing competition might evolve mechanisms that promote co-existence rather than exclusion.
Statement-$II$ : In endoparasites,morphological and anatomical features are greatly simplified while emphasising their reproductive potential.
In the light of the above statements,choose the correct answer from the options given below.

Explain the general information about population interaction and show the various outcomes observed between them.
