Abingdon tortoise in Galapagos islands became extinct within a decade after goats were introduced. It is an example of
1 Competition among unrelated species
2 Competitive exclusion
3 Competitive release
4 Coexistence better than exclusion
Explanation:
Abingdon tortoise in Galapagos islands became extinct within a decade after goats were introduced on the island, apparently due to the greater browsing efficiency of the goats. The competitive exclusion principle says that two species can't coexist if they occupy exactly the same niche (competing for identical resources) two species whose niches overlap may evolve by natural selection to have more distinct niches, resulting in resource partitioning.

All the following interactions are mutualism, except
1 association of algae and fungi in lichens
2 association of fungi and roots of higher plants in mycorrhiza
3 plant and animal relation for pollination
4 association of cattle egret and grazing cattle
Explanation:
Lichen, mycorrhizae and plant-animal relationship are example of mutualism. Cattle egrets follow grazing cows and eat the flies and bugs that tend to bother the cattle. The movement of foraging livestock also dislodges various insects from the field witch cattle egrets feed on.

Connel's field experiment on the rocky sea coast of Scotland, where larger Barnacle balanus dominates the intertidal area and removes the smaller Barnacle chathamalus. This happened due to
1 Predation
2 Competition
3 Parasitism
4 Mutualism
Explanation:
Connel's field experiment on the rocky sea coast of Scotland, where larger Barnacle balanus dominates the intertidal area and removes the smaller Barnacle chathamalus. This happened due to competition. In general, herbivores and plants appear to be more adversely affected by competition than carnivores.

From the given options, identify the correct combination of population interactions that correspond to the symbols given here $++\quad--\quad+O$
1 Predation Competition Commensalism
2 Mutualism Parasitism Amensalism
3 Parasitism Competition Mutualism
4 Mutualism Competition Commensalism
Explanation:
In mutualism, both the host and the predator will get benefitted. Competition is not a relationship but fights for something therefore competition is best defined as a process in which fitness of one species is significantly lower in the presence of another species. In commensalism the one get benefitted by other but do not harm the other.
