Darwin identified three forms of animal struggle for their existence. The first form is a struggle between one species (intraspecific form). The strong get better conditions, and the weak die out. Also, the species can fight with other species for prey, so as not to become prey, for good habitats, and so on. This is the second form, which is called interspecific. The third form of struggle is the most merciless and has caused the extinction of approximately 96 – 98% of the species on our planet. This is a fight against environmental factors. This includes warming, cold snaps, showers, hurricanes, and more.
