There exist three basic types of selection in an ecosystem, they are:

1) Directional selection

2) Disruptive selection

3) Stabilizing selection

The example of directional selection can be: that if in a population of pigs those having the longest snouts survive better and ultimately their population increases.

Further Explanation:

In an ecosystem, those organisms that better fit in the environment gets selected and survives more and this occurs due to the phenomenon known as natural selection. Three types of selection that occur in a population are directional, disruptive and stabilizing selection.  

1) Directional selection: In this type of selection, those organisms having one of the extreme phenotypes get selected over the other type of phenotype. This leads to a shift in allele frequency.

2) Disruptive selection: In this type of selection, those organisms having extreme phenotype gets selected over the other type of phenotype.

3) Stabilizing selection: In this type of selection, those organisms having an intermediate phenotype gets selected over the other type of phenotype.

Example of the three types of selection: If in a population there are pigs that have a long snout, small and intermediate snout. If there is the selection of:

1) Only pigs having long snout then this indicates that directional selection has occurred.

2) Pigs having either long or small snouts then this indicates that disruptive selection has occurred.

3) Only pigs having an intermediate type of selection then this indicates that stabilizing selection has occurred.
