Question

The Eurasian water milfoil is a nonnative

species, which was once commonly sold as an
aquarium plant, and is now found growing in
many lakes in New York State. It has few
natural enemies, and grows rapidly, crowding
out many native species. This plant ruins fishing
areas and interferes with boating and other
water sports. This is an example of
(1) human consumption of finite resources
(2) an unintended consequence of adding an
organism to an ecosystem
(3) an abiotic factor having a negative effect on
an ecosystem
(4) the introduction of a species that has
increased the long-term biodiversity of an
ecosystem

Answer 1

it would be (2) or B

Step-by-step explanation:

Because if the plant is commonly sold as aquarium plants then they could have had an unintended consequence of adding an organism to an ecosystem.

Answer 2

The right answer for the question that is being asked and shown above is that: "(4) the introduction of a species that has increased the long-term biodiversity of an ecosystem." This plant ruins fishing areas and interferes with boating and other water sports. This is an example of the introduction of a species that has increased the long-term biodiversity of an ecosystem
