Small fish get stuck near the bottom of a shark and derives its nutrition from it. This kind of association is called as
1 antibiosis
2 commensalism
3 Predation

Association of animals belonging to different species, where both partners are benefitted, is called
1 commensalism
2 mutualism
3 colony
4 sympathy
Explanation:
Mutualism is a type of association where both the partners are benefitted. This is permanent and obligatory association involving a physiological interdependence. eg. lichens.

The principle of competitive exclusion was stated by
1 C. Darwin
2 GF Gause
3 Mac Arthur
4 Verhulst and Pearl
Explanation:
Two or more species with closely similar niche requirements can't exist indefinitely in the same area as soon or later they come into competition for possession of it. This is called as Gause competitive exclusion principle, which states that an ecological niche can't be simultaneously and completely occupied by established populations of more than one species. Two species can live in same habitat but not in the same niche. More similar the two niches are severe the competition is.

In a random mating population in equilibrium, which of the following brings about a change in gene frequency in a non-directional manner: -
1 Mutations
2 Random drift
3 Selection
4 Migration
Explanation:
In a random mating population in equilibrium random drift brings about a change in gene frequency in a non-directional manner. Random genetic drifts refers to the chance fluctuations in gene frequency. Random genetic drifts occurs in finite populations, even with completely random mating, and leads to changes in both genotype and allele frequencies.
