Most of the oxygen in the atmosphere is made by algae. Where do most of the algae live?
coastal ocean
deep ocean
ponds
lakes

Answers

Coastal Ocean!

Explanation: It’s important to remember that although the ocean produces at least 50 percent of the oxygen on Earth, roughly the same amount is consumed by marine life. Like animals on land, marine animals use oxygen to breathe, and both plants and animals use oxygen for cellular respiration. Oxygen is also consumed when dead plants and animals decay in the ocean.

This is particularly problematic when algal blooms die and the decomposition process uses oxygen faster than it can be replenished. This can create areas of extremely low oxygen concentrations, or hypoxia. These areas are often called dead zones, because the oxygen levels are too low to support most marine life.

NOAA’s National Centers for Coastal Ocean Science conducts extensive research and forecasting on algal blooms and hypoxia to lessen the harm done to the ocean ecosystem and human environment.

Most of the oxygen in the atmosphere is made by algae, with coastal oceans housing the majority of algae. Hence the correct option is A.

What is Algae?

Algae is defined as a member of a group of primarily aquatic photosynthetic organisms of the Protista kingdom. Algae is described as floating green matter on the surface of a pond, lake, river, still water, moist soil, stones that grow on wet surfaces. Therefore, they can synthesize their own food. They are found in water or in very moist places.

Algae play many important and beneficial roles in freshwater environments producing oxygen and consuming carbon dioxide that act as the base of the aquatic food chain, removing nutrients and pollutants from the water and stabilize sediments. Most of the oxygen in the atmosphere is made by algae, with coastal oceans housing the majority of algae.

Hence the correct option is A.
