The sun is important to all living things. It is the original energy source for all ecosystems. Plants contain special mechanisms that allow them to convert sunlight into energy. Plant cells obtain energy through a process called photosynthesis. This process uses solar energy to convert carbon dioxide and water into energy in the form of carbohydrates. It is a two-part process. First, the energy from solar radiation is trapped in the plant. Secondly, that energy is used to break down carbon dioxide and form glucose, the main energy molecule in plants. Plants, algae and some bacteria use photosynthesis to create energy used for growth, maintenance and reproduction. During cellular respiration, the energy from the glucose made during photosynthesis is used to produce energy molecules for growth and reproduction. The products of respiration are energy…show more content…
Autotrophs are organisms that can make their own food. The most important nutrients they need are carbon, hydrogen, and oxygen. ...The human body can also synthesize some nutrients, such as amino acids. However, most organisms need nutrients created by autotrophs, People and animals get most of their nutrients from food.Essential nutrients are nutrients that the human body is unable to synthesize. They must be obtained from food or water. Essential nutrients include carbohydrates, proteins, fats, vitamins, and minerals. Nutrient cycling is one of the most important processes that occur in an ecosystem. The nutrient cycle describes the use, movement, and recycling of nutrients in the environment. Valuable elements such as carbon, oxygen, hydrogen, phosphorus, and nitrogen are essential to life and must be recycled in order for organisms to exist. Nutrient cycles are inclusive of both living and non living components and involve biological, geological, and chemical processes. For this reason, these nutrient circuits are known as biogeochemical
