Through photosynthesis, certain organisms convert solar energy (sunlight) into chemical energy, which is then used to build carbohydrate molecules. … Therefore, directly or indirectly, the process of photosynthesis provides most of the energy required by living things on earth.
Why most living organisms depend on photosynthesis?
Photosynthesis is important to living organisms because it is the number one source of oxygen in the atmosphere. Without photosynthesis, the carbon cycle could not occur, oxygen-requiring life would not survive and plants would die. … Without photosynthesis there would be little to no oxygen on the planet.
Do all living things depend on the process of photosynthesis?
Every living thing needs a source of stored energy for survival, even plants! … Living things that can not harness and store energy themselves through photosynthesis (and this includes humans, animals, insects, bacteria, viruses) HAVE to use the energy harnessed and stored by plants to survive, or their battery runs out.
Is photosynthesis dependent on solar energy?
Photosynthesis: Photosynthesis uses solar energy, carbon dioxide, and water to produce energy-storing carbohydrates. … The energy from sunlight drives the reaction of carbon dioxide and water molecules to produce sugar and oxygen, as seen in the chemical equation for photosynthesis.
When oxygen is released as a result of photosynthesis what is its source?
The Two Parts of Photosynthesis
In the light-dependent reactions, which take place at the thylakoid membrane, chlorophyll absorbs energy from sunlight and then converts it into chemical energy with the use of water. The light-dependent reactions release oxygen from the hydrolysis of water as a byproduct.
Why is it proper to say all living organisms are dependent on solar energy?
Plants prepare their food using sunlight, water and carbon dioxide through photosynthesis. … So, we can say that all living organisms depend on solar energy because if there is lack of solar energy plant would not be able to synthesize as a result other organisms depend on plants would also face starvation.
What organisms are capable of carrying out photosynthesis?
Plants, algae, and a group of bacteria called cyanobacteria are the only organisms capable of performing photosynthesis (Figure 1). Because they use light to manufacture their own food, they are called photoautotrophs (literally, “self-feeders using light”).
What is the main purpose of photosynthesis?
Photosynthesis is the process by which plants use sunlight, water, and carbon dioxide to create oxygen and energy in the form of sugar.
What would happen if photosynthesis does not occur in plants?
If photosynthesis does not occur in plants then plants cannot synthesize the food. … The plants will not produce oxygen and then no animal life will be able to survive due to the absence of oxygen. We will not get oxygen, food, and life on this planet will be extinct.
Could photosynthesis occur in a plant on a cloudy day?
Could photosynthesis occur in a plant on a cloudy day? Yes Explain: Photosynthesis could occur because some sunlight is able to penetrate the clouds.
What happens if there is no photosynthesis in our nature?
Without photosynthesis there would be no supply of oxygen and slowly the oxygen would get used up by oxidation such as rust formation. Furthermore, by removing plants, all of the many many animals that depend on plants would get very very hungry and gradually die.
