crucial gas for life on Earth, necessary for respiration in animals and plants.<\/li>\n\n\n\n<li>The Earth&#8217;s atmosphere contains about 21% oxygen.<\/li>\n<\/ul>\n\n\n\n<hr

wp-block-list\">\n<li><strong>Photosynthesis<\/strong> is the process by which plants, algae, and some bacteria produce oxygen.<\/li>\n\n\n\n<li>In photosynthesis, plants take in carbon dioxide (CO\u2082) and water (H\u2082O) and, with the help of sunlight, convert them into glucose (C\u2086H\u2081\u2082O\u2086) and oxygen (O\u2082).<\/li>\n\n\n\n<li>The chemical equation for photosynthesis:<\/li>\n<\/ul>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"463\" height=\"57\"

especially trees, are the primary producers of oxygen.<\/li>\n\n\n\n<li>Forests, oceans, and grasslands are major sources of oxygen due to the high number of plants involved in photosynthesis.<\/li>\n<\/ul>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity is-style-wide\"\/>\n\n\n\n<h3 class=\"wp-block-heading has-text-color has-link-color has-large-font-size

plants<\/strong> like algae also contribute to the production of oxygen through photosynthesis.<\/li>\n\n\n\n<li>The oxygen produced by aquatic plants supports marine life and is essential for the oxygen balance in the atmosphere.<\/li>\n<\/ul>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity is-style-wide\"\/>\n\n\n\n<h3 class=\"wp-block-heading has-text-color has-link-color

wp-block-list\">\n<li>The <strong>carbon-oxygen cycle<\/strong> describes how carbon dioxide (CO\u2082) is absorbed by plants during photosynthesis and how oxygen (O\u2082) is released.<\/li>\n\n\n\n<li>Animals and humans breathe in oxygen and release carbon dioxide, which plants then absorb, creating a continuous cycle that replenishes oxygen in the atmosphere.<\/li>\n<\/ul>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity is-style-wide\"\/>\n\n\n\n<h3 class=\"wp-block-heading has-text-color has-link-color has-large-font-size

plants and algae, some bacteria and certain types of phytoplankton also contribute to oxygen production.<\/li>\n\n\n\n<li>Volcanic eruptions and weathering processes also contribute small amounts of oxygen, though they are not as significant as photosynthesis.<\/li>\n<\/ul>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity is-style-wide\"\/>\n\n\n\n<h3 class=\"wp-block-heading

class=\"has-large-font-size wp-block-list\">\n<li>The balance of oxygen in the atmosphere is essential for life on Earth.<\/li>\n\n\n\n<li>Deforestation, pollution, and climate change can affect
