Marine Science EOC Review

The Chemistry of aquatic ecosystems is determined by? (SC. L.17.2)

• amount of salts, nutrients, and oxygen dissolved in the water.
• number of other organisms present in the water
• amount of rainfall the water receives.
• biotic and abiotic factors in the water

One of the major differeces between freshwater and marine ecosystems is? (SC.L.17.2)

• Temperature
• Salinity
• Depth
• Food

A non-native plant or animal that enters an area, out competing native organisms for resources is called what? (SC.L.17.8)

• Intruder species
• biological species
• invasive species
• immigrant species

One of the main cause of biodiversity loss is? (SC.L.17.8)

• Habitat fragmentaion

• invasive species

• climate change

• all answers shown

Which of the following is NOT correct concerning the nitrogen cycle? (SC.L.17.10)

• Nitrogen is an wlement neede to produce amino acids
• Atmospheric nitrogen is converted to ammoniam by certain bacteria
• Denitrification is when astmospheric nitrogen is changed into ammonia
• Plants use nitrates in the soil to make protiens

Suppose humans modified the carbon cycle by burning more fossil fuels. Which statement offers the best prediction for what would happen? (SC. L.17.10)

• The animals would increase their rate of respiration
• the amount of carbon dioxied in the carbon cycle would increase
• the amount of carbon dioxide in the carbon cycle would decrease
• the extra carbon diouxe would support more photosythesis by plants

Which of the following is NOT true about the water cycle? (SC.L.17.10)

• Water evaporates through transporation and from the ocean surface
• precipitation the falls to the surface and is NOT absorbed by the ground IS CALLED ground water
• Condensation is when water vapor condeses to form clouds
• Runoff is when water runs across the surface of the earth and eventually finds away to the ocean

The process of succession is? (SC.L.17.4)

• Demonstrates that ecosystems are always chainging
• Leads to a stable ecosystem in which no further changes occur
• Always begings on bare land or rock
• Always results from a sudden disturbance, such as a volcanic eruption

Which of the following is considered to be an ABIOTIC FACTOR in the environment? (SC.L.17.7)

• Water
• Trees
• Plants
• Animals

Biotic factors in a coral reef depend on abiotic factors like temperature and pH? (SC.L.17.7)

• TRUE
• FALSE
