why is photosynthesis important for life on earth

hotosynthesis is plants taking in water, carbon dioxide, and light to make sugar and oxygen. This is important because all living things need oxygen to survive. All producers make oxygen and sugar for the secondary consumers and then the carnivores eat animals that eat the plants. If there is not enough producers to make the sugar and oxygen that all living things need then all living things will die out. Without producers CO2 couldn't be taken in by the plants to be turned back into oxygen that all animals need for survival. Also, without producers, herbivores wouldn't have anything to eat and they would all die leaving carnivores without food to eat and all life forms wouldn't be on Earth.


Photosynthesis happens in the Chloroplast of the plant's organelle, if the Chloroplast wasn't in the plant Photosynthesis couldn't happen. If there was no sunlight for the plant to absorb then Photosynthesis couldn't happen. If living things didn't breathe out CO2 then the plants would die and living things would have no way of getting oxygen. These are the reasons why Photosynthesis is important to plants and all loving things on the planet.
Photosynthesis is a vital source of energy for nearly all living organisms, not just plants. The process is a chemical reaction that occurs in plants, algae and bacteria. It converts carbon dioxide in the atmosphere into organic compounds like sugar, providing the world with an energy source that is transferred to other organisms.


Plants, algae and bacteria transform light energy into chemical energy that is useful to all living organisms. This process is referred to as primary production and those photosynthetic organisms are called. They form the base of the food chain. Plants, Algae and Bacteria Plants, algae and bacteria use photosynthesis as a direct energy source. They convert carbon dioxide into carbohydrates for use as an energy source. The energy is used towards the growth and reproduction of the organism. Energy not used for growth or reproduction is lost through plant respiration.


According to the biophysicist Alfred Lotkaвs principles of thermodynamics, the energy retained by a primary producer is transferred to the herbivore that consumes it. Similarly, when a carnivore consumes an herbivore the energy of the herbivore, to which the primary producer contributed, is transferred to the carnivore. This process of energy transfer is called the food chain and describes the transfer of energy through an ecosystem. Because energy begins with primary producers, all organisms in an ecosystem indirectly rely on photosynthesis. In addition to providing energy in the form of carbohydrates, photosynthesis exports oxygen as a byproduct. Animals and other organisms use the oxygen for respiration.


Chemoautotrophs are organisms that produce organic compounds from the energy obtained through oxidation of inorganic compounds rather than organic, as in photoautotrophs like plants. They live in rocks and near hydrothermal vents in deep ocean ecosystems. They are the only organisms that do not rely on photosynthesis for energy. Chemoautotrophs produce energy from the reaction of hydrogen sulfide from the hydrothermal vents and oxygen from seawater. Organisms in the community around these vents consume the chemoautotrophs, which are most often bacteria, and begin the transferring of energy, making the bacteria a primary producer.
