Question

A massive toxic spill kills off half the population of photosynthetic

plankton in the ocean. What do you predict may happen to the
environment as a result of this event?
O There would be no change.
O The amount of oxygen in the environment would increase.
O The amount of oxygen in the environment would decrease.
O The amount of carbon dioxide in the environment would decrease.

Answer 1

A toxic spill killing off half the population of photosynthetic plankton in the ocean can lead to a decrease in oxygen production, affecting fish and other aquatic animals. The change in water pH may also disrupt metabolic processes. So the correct answer is Option C.

Step-by-step explanation:

When a massive toxic spill kills off half the population of photosynthetic plankton in the ocean, it can have severe consequences on the environment. With fewer photosynthetic organisms, oxygen production decreases, resulting in a decrease in the amount of oxygen in the environment. This depletion of oxygen can have negative effects on fish and other aquatic animals. Additionally, the pH of the water may change, impacting metabolic processes.
