Ocean

Artificial reefs are manmade structures that provide surfaces for algae and other invertebrates such as barnacles, to attach. In turn, these reefs attract fish and larger predators. Which statement describes a positive effect of artificial reefs on the ocean system?

• These created habitats could increase the local shark population, which might increase the number of shark attacks on humans

• The increased fish population may lead to overfishing on the coasts

• Materials within the artificial reef could contain toxins that damage the marine ecosystem

• There is an increase in biodiversity in the ocean system

Humans depend on ecosystems such as the ocean for survival, yet human activities may alter the ocean system. According to research, all of the following are negative impacts of human activity on the ocean system EXCEPT -

• pollution

• oil rigs

• species invasion

• nutrient-rich water

Unrestricted coastal development, pollution, and destructive fishing are some of the human activities that deplete ocean marine life. Which human activity is NOT beneficial to conservation of the ocean system?

• Reduction of plastic consumption

• Proper disposal of chemicals

• Release of wastewater

• Artificial reef programs

How have human activities modified ocean systems?

• Discarded plastics can trap, suffocate, and cause gastrointestinal problems for marine life, resulting in starvation

• Runoff with excessive chemicals can increase nutrients, resulting in more plant growth and reducing the dissolved oxygen content of the water

• Oil from oil spills penetrates the fur and feathers of organisms, causing vulnerability to temperature changes and decreasing buoyancy in water

• All of the answer choices

Which ocean activity is NOT related to survival of humans?

• The oceans store solar energy that helps keep Earth warm

• Marine algae produce a large percentage of the world's oxygen and absorb carbon dioxide

• The oceans play an important role in global weather patterns

• Oceans provide drinking water for most of the world's population

How might the information most directly affect the ocean?

• Fish populations increase along the coasts

• Runoff from coastal cities carries more pollutants

• More artificial reefs appear off the coasts

• Shark attacks decrease
