Question

1. which correctly describes how the ocean contributes to the oxygen that we breathe?○ fish produce oxygen through the process of respiration.○ phytoplankton produce oxygen through the process of photosynthesis.○ corals produce oxygen through the process of mineralization.○ phytoplankton produce oxygen through the process of respiration.clear all

Explanation:

Respiration consumes oxygen and releases carbon dioxide, so fish and phytoplankton doing respiration do not produce oxygen for atmospheric oxygen. Mineralization by corals breaks down organic matter and does not generate oxygen. Phytoplankton, as aquatic photosynthetic organisms, use sunlight, carbon dioxide, and water to produce glucose and release oxygen as a byproduct, which contributes significantly to the oxygen we breathe.

Answer:

Phytoplankton produce oxygen through the process of photosynthesis.
