Respuesta :

Answer: They may be wind blown, rain splashed, carried by animals, or moved in soil or water. Almost all short-distance spread is through these natural dispersal mechanisms. In their home territory, short distance spread is rarely a problem because the resident plants and animals have evolved to coexist more or less peaceably.

Explanation:

Humans can help in the spread of invasive species.

What is an invasive species?

  • It is a species that is not naturally present in an area ("not native") and when introduced in that area disturbs the ecosystem.
  • For example, Eichhornia crassipes, cane toad, etc.

How can human spread the invasive species?

Humans can help in the spread of invasive species:

  • A species is introduced due to its beauty - because of its beautiful flowers and leaf shapes, the water hyacinth was brought to India.
  • It is a contaminant of a species that is introduced - Parthenium is thought to have arrived in India as a contamination in PL 480 wheat from the United States.
  • They may be brought accidentally- Zebra mussels arrived in North America's Great Lakes by accident, clinging to big ships.
  • To control the population of other species - Small Indian mongooses were introduced with the goal of controlling rats that were ruining the sugarcane crop.
