What would an increase in atmospheric co2 levels cause a decrease in ___ in the ocean?
Because of human-driven increased levels of carbon dioxide in the atmosphere, there is more CO2 dissolving into the ocean. The ocean’s average pH is now around 8.1 , which is basic (or alkaline), but as the ocean continues to absorb more CO2, the pH decreases and the ocean becomes more acidic.

How does an increase in CO2 carbon dioxide levels in the ocean affect ocean life?
Carbon pollution is changing the ocean’s chemistry, slowing its ability to uptake CO2, making it more acidic, and harming shellfish and other marine life we depend on.

What are some problems that CO2 can cause in the ocean?
The massive amount of carbon dioxide being absorbed by the ocean dissolves in seawater as carbonic acid. This process is known as ocean acidification, and it’s literally causing a sea change that is threatening the fundamental chemical balance of ocean and coastal waters from pole to pole.

When CO2 in the atmosphere increases what happens to the oceans quizlet?
As Carbon dioxide in the atmosphere increases it sinks to the ocean and dissolves in water creating carbonic acid which is bad for marine organisms. the PH decreased in the ocean and the ocean water becomes more acidic.

What is true about eutrophication in marine ecosystems?
Primary Impacts Eutrophication leads to an increased algal growth (because the level of nutrients increases). It can lead to a shift in species composition to fast growing algae species (including toxic species) and a shift from long lived macroalgae to more nuisance species.

What causes marine eutrophication?
An overabundance of nutrients—primarily nitrogen and phosphorus—in water starts a process called eutrophication. Algae feed on the nutrients, growing, spreading, and turning the water green. Algae blooms can smell bad, block sunlight, and even release toxins in some cases.

What is true about eutrophication quizlet?
Eutrophication is the process by which fertilizers in a lake build up over time & cause an increase in algae. This can cause lakes to become grassy meadows. The speed of this process is increased by lawn fertilizers, & dog & geese waste.
