Question

Which activity involving our oceans would impact the carbon cycle?

Dumping of sewage in the ocean will result in increased oceanic carbon dioxide due to algal blooms.
Removal of oil from the ocean floor for use as fuel will result in increased atmospheric carbon dioxide.
Overfishing of primary consumers will increase oceanic carbon dioxide as producers increase in population.
Increased sediment runoff from development will decrease carbon dioxide as photosynthesis decreases.

Answer 1

Dumping of sewage, removal of oil, and overfishing of primary consumers can impact the carbon cycle.

Step-by-step explanation:

One activity involving our oceans that would impact the carbon cycle is the dumping of sewage. When sewage is dumped in the ocean, it can lead to algal blooms. These blooms can result in increased oceanic carbon dioxide levels as the algae undergo photosynthesis and release carbon dioxide.

Another activity that can impact the carbon cycle is the removal of oil from the ocean floor for use as fuel. This process can release carbon dioxide into the atmosphere when the oil is burned as fuel.

The overfishing of primary consumers can also affect the carbon cycle. When primary consumers, such as herbivorous fish, are overfished, the population of producers, such as algae or phytoplankton, can increase. This can lead to more carbon dioxide being absorbed from the atmosphere through photosynthesis and stored in the ocean.
