which of the following best describes an invasive species?
native or non - native species found in nearly every terrestrial area
native plants or animals which grow at an exceptionally fast rate
non - native species introduced to an area ultimately harming the ecosystem or human health
native plants which take up large areas of space and do not allow for other species to spread

Explanation:

To determine the best description of an invasive species, we analyze each option:

• The first option describes a widespread species (native or non - native) but not the key characteristic of invasiveness (harm).
• The second option refers to native species with fast growth, but invasive species are non - native.
• The third option: Invasive species are non - native, introduced to a new area, and cause harm to the ecosystem or human health. This matches the definition.
• The fourth option describes native plants that dominate space, but invasive species are non - native.

Answer:

C. Non - native species introduced to an area ultimately harming the ecosystem or human health
