Answer:
competitive exclusion.
Explanation:
When species from the same biological community explore very similar ecological niches, competition among them for less available resources in the environment is instituted. It is common, for example, that plant species whose roots use the same portion of the soil compete for water, minerals and other resources.
Knowing this, Russian biologist Georgyi Frantsevich Gause formulated the Gause principle, or competitive exclusion principle, the theory that ecological niches are unique to each species, and for two or more of them to coexist in the same habitat, it is necessary that their niches have different and sufficient characteristics.
Gause proposed this theory based on several observations that led him to conclude that if two or more species explore exactly the same ecological niche, the competition established between them is so sharp that coexistence becomes impossible. This can cause a loss in species diversity, and that is exactly what Robert Paine observed in his studies.
The correct answer to this open question is the following.
Although there are no options attached we can comment on the following.
Immigrants from China made up a large portion of the labor force during the California gold Rush for the following two reasons:
1) They arrived at the port of San Francisco, California, from China. 2) They worked as miners in the California gold mines and were paid low salaries, working under extremely unhealthy and risky conditions.
Chinese immigrants were treated badly because they were foreigners in a foreign land. White miners were jealous of the Chinese miners because Chinese miners worked very hard and were more efficient.
Years later, in the 1860s, and with the passing of the Pacific Railroad Act, Chinese people worked in the Transcontinental Railroad.

Answer:
A strict ruler and a strong legal system is needed to create an orderly society.
Explanation:
Legalism was an Ancient Chinese philosophy. According to this philosophy, in order to create a stable and orderly society, a strong leader, and strong laws are needed. The strong leader should be able to amass wealth and power, in order for him to have incentive to rule in an orderly manner, and with a long-term perspective. Like this, legalism was a philosphy that justified the rule of one single emperor over an unified China.
