The correct answers are B. They do not have natural predators to regulate their population growth and E. They compete with native organisms for resources.
Explanation:
Nonnative species include any species that does not belong to an ecosystem but was introduced to it. Nonnative species are considered are an important threat to biodiversity and native species because they usually disrupt the natural equilibrium in the ecosystem.
This usually occurs because nonnative species population grow rapidly due to the lack of natural predators; for example, Asian carps which are native from Asia and were taken to the U.S. are eaten by other fish and animals in their native ecosystem, but once they are introduced in another ecosystem their population increases due to lack of predators. Additionally, nonnative species often compete with native species for resources, this also happens with the Asian carp that competes for food such as snails or mussels with native species in the U.S.
Answer:
B. runoff of nitrates from fertilizers applied to the golf course
Explanation:
Algal bloom is defined as the rapid growth of algae in freshwater or marine water. Algal bloom is green or yellowish in color that cover the top layer of water systems.
Algal bloom in the given case is caused by the excess of nutrients that is nitrates from fertilizers into waters and higher concentrations of nitrates causes uncontrollable growth of algae.
Algal blooms are harmful for environment as they may produce toxins and can block the sunlight from reaching the plants and animals in the water systems.
Hence, the correct answer is "B. runoff of nitrates from fertilizers applied to the golf course".
