It includes the land, water, and air, as well as all the organisms that live in these areas. The biosphere is a dynamic system that is constantly changing. It is affected by the Earth&#8217;s climate, geology, and biology.<\/p>\n<p>The biosphere is divided into several different zones, based on the type of life that exists in each zone. The terrestrial biosphere includes all the land on Earth, from the poles to the equator. The aquatic biosphere includes all the water on Earth, from the oceans to the lakes and rivers. The atmospheric biosphere includes the air around Earth.<\/p>\n<p>The biosphere is essential for life on Earth. It provides the air we breathe, the water we drink, and the food we eat. It also provides the habitat for all the plants and animals that live on Earth.<\/p>\n<p>The biosphere is a fragile system. It can be damaged by human activities, such as pollution and climate change. It is important to protect the biosphere so that life on Earth can continue.<\/p>\n<p>The other options are incorrect because:<\/p>\n<ul>\n<li>The stratosphere is the second <div class=\"youtube-subscribe-container\">\r\n        <a href=\"https:\/\/www.youtube.com\/channel\/UCNHT8lW-JmLC68rjBfZhdkg?sub_confirmation=1\" target=\"_blank\" class=\"youtube-subscribe-button\">\r\n            <span class=\"youtube-icon\">\r\n                <svg xmlns=\"http:\/\/www.w3.org\/2000\/svg\" viewBox=\"0 0 576 512\">\r\n                    <path d=\"M549.7 124.1c-6.3-23.7-24.8-42.3-48.3-48.6C458.8 64 288 64 288 64S117.2 64 74.6 75.5c-23.5 6.3-42 24.9-48.3 48.6-11.4 42.9-11.4 132.3-11.4 132.3s0 89.4 11.4 132.3c6.3 23.7 24.8 41.5 48.3 47.8C117.2 448 288 448 288 448s170.8 0 213.4-11.5c23.5-6.3 42-24.2 48.3-47.8 11.4-42.9 11.4-132.3 11.4-132.3s0-89.4-11.4-132.3zm-317.5 213.5V175.2l142.7 81.2-142.7 81.2z\"\/>\r\n                <\/svg>\r\n            <\/span>\r\n            Subscribe on YouTube\r\n        <\/a>\r\n    <\/div> layer of Earth&#8217;s atmosphere, above the troposphere and below the mesosphere.
