carried in on cargo crates

result from mutations in other organisms

coevolution of two species

Answer 1

Check all that apply:

- carried in on cargo crates — Yes (wood-boring insects, fungi, etc.)
- transported in or on ships — Yes (ballast water, hull fouling, stowaways)
- result from mutations in other organisms — No (mutation creates variation within a population, not an introduction to a new ecosystem)
- hidden inside produce or meat — Yes (fruit/vegetable pests, parasites)
- carried on clothing or in luggage — Yes (seeds, insects, spores)
- intentionally introduced by humans — Yes (pets, crops, biocontrols, ornamental plants)
- coevolution of two species — No (coevolution is an ecological/evolutionary process, not a transport/introduction mechanism)
