You are presented with the question "having what increases the potential to produce more offspring than the environment can support?" and the following answer choices: 
- no natural habitat
 - no natural prey
 - competing for resources
 - peachleaf willow
 - no natural owners
 - members of their own species
 - animals with backbones
 - no natural predators

Now knowing that having no natural predators increases population size and any population has the potential to produce more offspring than the environment can support, choose the best answer.
