A. storms over the ocean B. objects that have been sunk C. overfishing of habitats D. tires that washed up on beaches

Which of these is evidence of the disavantage of artificial reefs? A.

C. overfishing of habitats

To determine which of the options is evidence of the disadvantage of artificial reefs, we need to understand what disadvantages are associated with artificial reefs. Artificial reefs are human-made structures placed in bodies of water to create new habitats for marine life and to promote ecosystem development. While they have many advantages, such as creating new habitats and supporting biodiversity, there are also potential disadvantages associated with them.

Let's evaluate each option:

A. Storms over the ocean: This option does not specifically indicate a disadvantage of artificial reefs. Storms are natural occurrences that impact various aspects of marine environments, and they can affect both natural and artificial reef systems.

B. Objects that have been sunk: This option does not provide direct evidence of the disadvantage of artificial reefs. Objects being sunk to create artificial reefs is actually one of the ways in which they are established. However, if these objects are pollutants or non-biodegradable materials, it could be seen as a disadvantage.

C. Overfishing of habitats: This option provides evidence of a disadvantage of artificial reefs. Artificial reefs can attract marine life, including commercially valuable fish species. If these habitats become overfished, it can negatively impact the balance of the ecosystem and reduce overall fish populations.

D. Tires that washed up on beaches: This option does not directly relate to the disadvantage of artificial reefs. While tires may be used as construction materials for artificial reefs, the presence of tires on beaches does not indicate a specific disadvantage of artificial reefs themselves.

Based on the evaluation, the option that provides evidence of the disadvantage of artificial reefs is:

C. Overfishing of habitats
