The correct answer is - cyanobacteria.
The atmospheric oxygen came from the cyanobacteria. These were one of the earliest living organisms on Earth. The cyanobacteria was using photosynthesis in order to create its own food. The photosynthesis process requires sunlight, carbon dioxide, water, and oxygen. The oxygen is mostly released as a waste product from the process of photosynthesis, thus the cyanobacteria were literally releasing oxygen that was ending up into the atmosphere. As more and more cyanobacteria there were across the planet, more and more oxygen they were releasing into the atmosphere, slowly changing the composition of the atmosphere, and setting the basis of it as we know it now.
Based on the calculations, the approximate area covered by the reservoir is equal to 0.28 km².
<h3>What is the area of a circle?</h3>
The area of a circle simply refers to the space occupied or the region enclosed by a circle within its boundary, and in a two-dimensional plane.
<h3>How to calculate the area of a circle?</h3>
Mathematically, the area of a circle is calculated by using this formula:
Area = πr²
<u>Where:</u>
r is the radius of a circle.
<u>Given the following data:</u>
Diameter of circle = 0.6 kilometer.
π = 3.14.
Radius = 0.6/2 = 0.3 km.
Substituting the given parameters into the formula, we have;
Area = π × 0.3²
Area = 3.14 × 0.09
Area = 0.28 km².

In the mid-twentieth century and corroborated ever since, researchers dredging the seafloor could not find any materials older than 180 million years.
<h3>
What do you understand by seafloor ?</h3>
The surface of an ocean or sea: seafloor According to this theory, the Earth's crust is divided into a number of enormous plates that together form the continents and ocean floors and are supported by a warm, plastic "mantle" beneath the surface. Mr. Walter Sullivan
Deposits of common minerals like copper, zinc, nickel, gold, silver, and phosphorus can be found on the seafloor. These deposits are nodules on silt from the abyssal plain that are typically 3 to 10 centimeters (1 to 4 inches) in diameter and appear as crusts on volcanic and other rocks.

Answer: It is located in the Darling River.
Explanation:
The Sutherland Falls is a large waterfall so named after Donald Sutherland who was the first Westerner to discover the falls in 1880.
It has a drop of 1,904 ft and indeed is one of the world’s largest waterfalls.
Located on New Zealand’s South Island, it falls from Lake Quill not the Darling River.
Indeed the Darling River is located in Australia not New Zealand making yhe last option incorrect.
