Why is photosynthesis vital for life quizlet?
Photosynthesis is vital for plant life, because it provides plants with a means to produce energy. Photosynthesis indirectly provides organisms that feed on plants with energy as well.
What are the three reasons why photosynthesis is important?
Photosynthesis and why it’s important Photosynthesis 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.
Why is photosynthesis considered as the basic life process?
Photosynthesis is the only process that utilizes energy from sun to produce food for millions of organisms. This is only process which adds oxygen to the atmosphere. This photosynthesis is the basic life process for the sustenance of organisms in general and man in particular.
What is importance of photosynthesis?
Answer Expert Verified It is the ultimate source of Oxygen and energy for all living organisms. 2. Photosynthesis provides food for all living beings. The process of photosynthesis occurs in green plants which are the primary producers in a food chain.
Why are there different types of carbon fixation?
There are different types of carbon fixation, because plants are located in regions with different conditions. CAM plants are adapted to arid conditions, while C3 plants are adapted to areas with moderate light and temperatures. CAM plants convert carbon dioxide to acid and store it during the night.
How is oxygen used in photosynthesis?
In photosynthesis, solar energy is harvested as chemical energy in a process that converts water and carbon dioxide to glucose. Oxygen is released as a byproduct. In cellular respiration, oxygen is used to break down glucose, releasing chemical energy and heat in the process.
How do humans benefit from photosynthesis?
Photosynthesis provides us with most of the oxygen we need in order to breathe. Plantshelp humans survive by giving out carbon dioxide to oxygen through a process called photosynthesis that helps us to breathe.
How does photosynthesis affect humans?
In the process, they produce oxygen, which constitutes a significant portion of the air we breathe so less plants means less recycling of carbon dioxide and less oxygen production. Plants also give us food and fibers to make clothes and without photosynthesis, we would not be able to sustain the life we are living.
How do plants benefit from humans?
In a way, they are a cycle — plants help humans breathe by providing us with oxygen, and humans help plants “breathe” by providing them with carbon dioxide.
Which is the most important life process?
Answer. Nutrition is considered as one of the most important life process because it is involved in production of energy. Explanation: The process through which living organism gets it energy through the food is called as nutrition.
Can photosynthesis happen without sunlight?
Plants need light to photosynthesize, but it doesn’t necessarily have to be sunlight. If the correct type of artificial light is used, photosynthesis can happen at night with lights that contain blue and red wavelengths.
What is the importance of photosynthesis Class 7?
Photosynthesis helps to maintain a balance between oxygen and carbon dioxide in the atmosphere as it absorbs carbon dioxide and release oxygen. Sunlight is necessary for photosynthesis. Thus sun is the ultimate source of energy for all living organism. Our earth is the unique planet, where photosynthesis takes place.
What are 2 benefits of photosynthesis?
Green plants and trees use photosynthesis to make food from sunlight, carbon dioxide and water in the atmosphere: It is their primary source of energy. The importance of photosynthesis in our life is the oxygen it produces. Without photosynthesis there would be little to no oxygen on the planet.
What is photosynthesis very short answer?
Photosynthesis is a process by which phototrophs convert light energy into chemical energy, which is later used to fuel cellular activities. The chemical energy is stored in the form of sugars, which are created from water and carbon dioxide.
What are the 4 factors that affect photosynthesis?
Photosynthesis is affected by light, temperature, water, and CO2. Stomata affect the process of transpiration and do not affect photosynthesis.
