Why are photosynthetic organisms so important to life on Earth How does photosynthesis relate to cellular respiration?
While cellular respiration releases carbon dioxide into the environment photosynthesis pulls carbon dioxide out of the atmosphere. The exchange of carbon dioxide and oxygen during photosynthesis and cellular respiration worldwide helps to keep atmospheric oxygen and carbon dioxide at stable levels.
What are 5 facts about photosynthesis?
10 Facts on Photosynthesis
- The green color of leaves is due to chlorophyll. …
- The two main parts of a chloroplast are the grana and stroma. …
- The first stage of photosynthesis captures energy from the sun to break down water molecules. …
- The second stage of photosynthesis is the Calvin cycle.
What is the main product of photosynthesis?
glucoseThe products of photosynthesis are glucose and oxygen. Although the hydrogen atoms from the water molecules are used in the photosynthesis reactions the oxygen molecules are released as oxygen gas (O2). (This is good news for organisms like humans and plants that use oxygen to carry out cellular respiration!)
Can life exist without photosynthesis?
If there was no photosynthesis plants and animals likely could not exist. In addition the atmosphere would have very little oxygen because photosynthesis releases a large amount of oxygen into the air. … Otherwise the Earth would be a pretty barren lifeless place without photosynthesis.
What is the role of photosynthesis in the ecosystem quizlet?
What is the role of photosynthesis and respiration in ecosystems? Photosynthesis (stores energy of biomass) and respiration (releases the stores of biomass) control the flow of energy. Process by which green plants convert light energy from the sun into chemical energy that is stored in organic matter.
How is photosynthesis important to humans?
Plants make their own food and pass there energy down to humans when we consume the nutrients from the plants. Photosynthesis creates clean air for humans to breathe. It also allows plants to grow which feeds humans.
What is photosynthesis and why is it important quizlet?
Why is photosynthesis so important? It is the process that plants use to make their own food so that they become the base of the food chain. It produces oxygen that all living things need for cellular respiration.
What cell structures are most important to photosynthesis Why?
Chloroplasts are plant cell organelles that convert light energy into relatively stable chemical energy via the photosynthetic process. By doing so they sustain life on Earth. Chloroplasts also provide diverse metabolic activities for plant cells including the synthesis of fatty acids membrane lipids …
What energy is needed by photosynthetic organisms during the process of photosynthesis?
During the process of photosynthesis cells use carbon dioxide and energy from the Sun to make sugar molecules and oxygen. These sugar molecules are the basis for more complex molecules made by the photosynthetic cell such as glucose.
How does photosynthesis process benefit man society and the environment Brainly?
Photosynthesis is important for people and animals as oxygen is released as a by product during photosynthesis which is an essential requirement for the survival of animals and human beings. All life forms on earth require oxygen for respiration.
What is the importance of photosynthesis to organisms other than plants?
What is the importance of photosynthesis to organisms other than plants? Photosynthesis captures energy that other organisms access when they eat either plants or organisms that eat plants. the amount of photosynthesis occurring exceeded the amount of cellular respiration.

What important roles do autotrophs play in the ecosystem?
autotroph in ecology an organism that serves as a primary producer in a food chain. Autotrophs obtain energy and nutrients by harnessing sunlight through photosynthesis (photoautotrophs) or more rarely obtain chemical energy through oxidation (chemoautotrophs) to make organic substances from inorganic ones.
Why are producers so important to an ecosystem?
Producers are extremely important living things within an ecosystem because they make food for other organisms.
What is the most important role of photosynthetic organisms in an ecosystem?
Photosynthetic organisms including plants algae and some bacteria play a key ecological role. They introduce chemical energy and fixed carbon into ecosystems by using light to synthesize sugars.
Why are photosynthetic autotrophs important to the ecosystem?
Photosynthetic autotrophs are important to an ecosystem because they produce food for the heterotrophs. Autotrophs are able to make their own food…
What are 3 things about photosynthesis?
To perform photosynthesis plants need three things: carbon dioxide water and sunlight.
What are two important things about photosynthesis?
Photosynthesis requires carbon dioxide and water to make sugar and oxygen. Cellular respiration uses oxygen and sugar to release energy carbon dioxide and water. Plants and other photosynthetic organisms perform both sets of reactions. See also how to catch a wave on a longboard
Why does photosynthesis take place in the absence of sunlight?
Both photosynthesis and respiration occur within plant cells. … At night or in the absence of light photosynthesis in plants stops and respiration is the dominant process. The plant uses energy from the glucose it produced for growth and other metabolic processes.
What is the important role of decomposers in an ecosystem?
Decomposers include saprophytes such as fungi and bacteria. They directly thrive on the dead and decaying organic matter. Decomposers are essential for the ecosystem as they help in recycling nutrients to be reused by plants. … They provide space for new being in the biosphere by decomposing the dead.
