Species can be introduced to new ecosystems through the following means:

  • Carried in on cargo crates
  • Transported in or on ships
  • Hidden inside produce or meat
  • Carried on clothing or in luggage
  • Intentionally introduced by humans

The options related to resulting from mutations in other organisms and coevolution of two species do not directly pertain to the introduction of species to new ecosystems. Coevolution refers to the process by which two or more species influence each other's evolution, while mutations occur within species rather than introducing them to new environments.

How do introduced species become established in a new ecosystem? Check all that apply.

introduced to a habitat similar to their own

introduced to a habitat different than their own

outcompete native species

generally have no native predators

generally have native predators

often have high reproductive rates

often have low reproductive rates

can tolerate a range of conditions

Introduced species can become established in a new ecosystem through the following means:

  • Introduced to a habitat similar to their own
  • Outcompete native species
  • Generally have no native predators
  • Often have high reproductive rates
  • Can tolerate a range of conditions

The options introduced to a habitat different than their own and generally have native predators are less likely to facilitate establishment; while some species can adapt to different habitats, many require conditions similar to their native environment to thrive. Additionally, the presence of native predators can hinder the establishment of introduced species. The reproductive rates impacting establishment depend on the specific species and context, but generally, high reproductive rates can aid establishment.
