IV. Effects of Ko'p hujayrali hayvonlarni kelib chiqish
The effects of the emergence of multiple species of animals can have both positive and negative impacts 
on ecosystems and the human population. The positive effects can include an increase in biodiversity and 
the potential for new discoveries and scientific research. For example, the discovery of a new species of 
plant or animal can lead to the development of new medicines or technologies. However, the negative 
effects of these introductions can cause significant ecological and economic damage. They can result in 
the displacement of native species, the introduction of exotic diseases and parasites, and the depletion of 
resources necessary for native species to survive. The effects of the introduction of multiple exotic species 
can also impact human populations. This includes the loss of crops and livestock as resources, and the 
potential for increased human-wildlife conflict. As such, it is important to carefully consider and manage 
the introduction of multiple exotic species to mitigate any potential negative impacts.
A. Competition for resources
One key factor in the emergence and continuation of animal migration is competition for resources. 
Animals have evolved to move in search of food, water, and shelter to avoid starvation, dehydration, or 
exposure to harsh weather conditions. However, competition for limited resources, such as grazing land, 
waterholes, or safe breeding grounds, can exacerbate migration patterns, leading to highly synchronized 
mass movements of animals. This phenomenon is particularly evident in the savannas and grasslands of 

---

Africa, where large herbivores like wildebeest and zebras migrate seasonally along established paths. 
The competition for resources also affects animal behavior and ecology, as it generates complex social 
patterns, such as territorial disputes, alliances, or hierarchical structures, that can impact survival and 
reproductive success. Therefore, understanding the role of competition for resources in animal migration 
is crucial to predict and manage the impacts of environmental changes and anthropogenic disturbances 
on ecosystem dynamics and biodiversity.
