Answer 1

The option that best describes an invasive species is 'Non-native species introduced to an area ultimately harming the ecosystem or human health'.

Step-by-step explanation:

The invasive species is best described as a non-native organism that, when introduced to an area outside of its native range, threatens the ecosystem balance and may even harm human health.

In the U.S., invasive species such as the purple loosestrife and the zebra mussel have significantly altered the ecosystems they have invaded.

Invasive species often lack natural predators in their new environments, allowing them to proliferate rapidly and out-compete native species for resources, leading to ecological disruptions and, in severe cases, extinction of native species.

Most damaging invasive species on the planet are:

• Giant cane.
• Shoebutton ardisia.
• Aphanomyces.
• Asian long-horned beetle.
• Malaria mosquito.
• Asian tiger mosquito.
