According to Concept 52.4, the distribution of species like kangaroos is influenced by a combination of factors. Which of the following best summarizes these influencing factors?

  • A: Primarily by present-day competition with other species for resources.
  • B: Solely by the availability of suitable habitats determined by abiotic factors such as temperature and rainfall.
  • C: A combination of evolutionary history (like continental isolation) and ecological factors, including both biotic and abiotic conditions.
  • D: Primarily by direct human intervention and conservation efforts.

Explanation

Concept 52.4 explicitly states that 'species distributions are a consequence of both ecological factors and evolutionary history.' It then elaborates on kangaroos, noting their origin during continental isolation evolutionary history and their specific habitats ecological factors, both biotic and abiotic .
