A) There are abiotic and biotic factors that keep population size of species under control Provide two examples that affect (or have affected) population size of native species in WA (one example for density dependent and one for density independent). You need to pick two real examples, provide specific species names and habitats/ecosystems where those species occur. You need to use different examples from the ones I used in lectures

b) Explain why species that overlap a great deal in their fundamental niches have a high probability of competing. Now explain why species that overlap a great deal in their realized niches and live in the same area, probably do not compete significantly.
c) What are two important pieces of ecological knowledge that you could apply to the decisions you make about your own life? Mainly from an ecological point of view, but it is good that you make a connection with other aspects of your life (personal or professional).

Answer A: A key example of biotic and abiotic protagonists is the presence of rocky structures that exist in the mountains of southern Argentina (Patagonia) that thanks to them exist the ideal temperatures for the procreation of animals such as the Patagonian condor and the possibility of form nests in these rocky structures that secure their young.

Answer B:

The explanation for this is that they have populations that increase in number and have their niches realized and constant resources necessary to develop the species in this way, considering the dominant species in the area and the one that predominates, in the case of fundamental niches. , they are necessary and even obligatory niches for many populations, which if populations do not go to them, they die, extinguish, or decrease their number, that is why in the face of this reality made up of a fundamental niche since it is fundamental to persist life of the population.

Answer c:

Two key principles are: one, maintain the equilibrium, that is why one seeks to have an environmentalist position preserving nature, and two considering that we are part of that balance but that does not give us the right to break it with environmental contamination, intervention of natural food systems and many other factors.
