The correct answer is: C.Orcas face less competition and increase in number.

A. Orcas face less competition and increase in number

With fewer sharks in the ecosystem due to poaching, orcas may face less competition for food sources, especially if sharks were competing with orcas for similar prey. This could lead to an increase in orca numbers as they can more easily access food resources that were once shared with sharks.

B. Orcas face more competition from other species

This is unlikely. While other marine predators may occupy some of the ecological niches left by the reduction in shark numbers, the immediate effect would likel...
