Positive Interactions :- Commensalism || Negative Interactions:- 1.Predation 2. Parasitism

Which of the following pairs are correctly matched ? 1. Amensalism - A population is inhibited whereas the other populations remain unaffected. 2. Predation - A population uses the other as its food. 3. Mutualism - Interaction favourable to both and obligatory. Select the correct answer using the codes given below : Answer codes :

If solute and solvent interactions are more than solute- solute and solvent -solvent interactions then

An interaction favourable to both the population , but not obligatory to either is :

Negative interactions among populations include parasitism also. Define parasitism. What are its types ? Differentiate between ectoparasites and endoparasites.
