Answer:
B. Herbicides
Explanation:
Nonnative species are species that are found outside their natural habitat. They are also called foreign species. They are introduced through the activities of man either deliberately or in-deliberately . They can be controlled by chemical, biological and mechanical means.
Mowing, net barriers and inspections are mechanical controls.
Biological control is the deliberate introduction of natural enemies of these nonnative/foreign species.
The use of herbicides is a chemical control of plants that grow where they are not wanted.
The correct statements are:
<em>2. Ecosystem B has more biodiversity than all the other ecosystems;</em>
The ecosystem B, as shown by the graph, is by far the one that has the most biodiversity, with 9 species living in this ecosystem. On the other hand, the ecosystem A has 5, while the ecosystem C only 3, and ecosystem D just 2 species.
<em>5. Ecosystem A has more biodiversity than ecosystem C but less biodiversity than ecosystem B;</em>
The ecosystem A has 5 species in its boundaries, and that makes it more diverse than the ecosystem C that only has 3 species in its boundaries. But ecosystem A is also almost twice less diverse than the most diverse ecosystem B which has 9 species in its boundaries.
