Photosynthesis is measured by the amount of oxygen produced. Counting pondweed bubbles or using the Audus apparatus to determine the amount of gas evolved over time can both be used to quantify oxygen.
<h3>
What is photosynthesis?</h3>
Photosynthesis is the conversion of light energy into chemical energy by green plants and other organisms. Light energy is collected and utilised by green plants during photosynthesis to convert water, carbon dioxide, and minerals into oxygen and energy-rich organic molecules.
The forming bubbles are either counted or recorded using light barriers, which is difficult due to their small size and frequently changing ascent velocity. When gas bubbles produced during photosynthesis by aquatic plants leave the plants, they produce different sound pulses.
B. Because the gas collected contains water vapor in addition to oxygen, it is not pure oxygen.

As many as 25 percent of the cowboys who participated in the Texas cattle drives were AFRICAN AMERICANS.
Cattle drive was a main economic activity in the Western part of America during the 19th century. The west were known for cattle breeding and they usually have to move these cattle from the home ranches to the rail-heads where they will be bought. The distance between these two points is always great and it may takes as much as two to three months before the distances are covered. The cowboy are the ones that drive the cattle to their selling points. Texas was particular successful in cow farming and as at that time about one fourth of the cows boys are of African American origin.<span />
An aphotic zone is a zone where light can be received from the sun (or other sources of light).
For example in the ocean, it will be the zone that begins a 200m deep and goes to the bottom of the sea.
