Which members of the ecosystem transform glucose?
Answer: Plants are the most obvious examples of producers; plants take energy from sunlight and use it to convert carbon dioxide into glucose (or other sugars). Algae and cyanobacteria are also photosynthetic producers, like plants.
Do consumers transform glucose into carbon dioxide?
Carbon dioxide is released back into the atmosphere during respiration of consumers, which breaks down glucose and other complex organic compounds and converts the carbon back to carbon dioxide for reuse by producers.
What role does photosynthesis play in the Earth as an ecosystem?
It provides energy for nearly all ecosystems. By transforming light energy into chemical energy, photosynthesis provides the energy used by organisms, whether those organisms are plants, grasshoppers, wolves, or fungi.
Which is produced during photosynthesis apes?
Photosynthesis : Example Question #4
Photosynthesis converts carbon dioxide, water, and solar energy to sugar and oxygen. Respiration uses oxygen and sugars to provide a cell with energy. Water and carbon dioxide are produced as byproducts.
Which of the following are producers of oxygen?
At least half of Earth’s oxygen comes from the ocean.
Scientists estimate that 50-80% of the oxygen production on Earth comes from the ocean. The majority of this production is from oceanic plankton — drifting plants, algae, and some bacteria that can photosynthesize.
When plants make glucose they are converting the sun’s radiant energy?
Plants use a process called photosynthesis to make food. During photosynthesis, plants trap light energy with their leaves. Plants use the energy of the sun to change water and carbon dioxide into a sugar called glucose. Glucose is used by plants for energy and to make other substances like cellulose and starch.
What is the role of oxygen in energy yielding pathways?
What is the role of oxygen in energy-yielding pathways? … Energy is cascaded down the chain from one carrier molecule to the next until the terminal electron receptor oxygen is reached. The oxygen pulls the electron down the chain in an energy-yielding tumble for the production of ATP.
Where do all the carbons of glucose end up?
Products of the Citric Acid Cycle
The two acetyl carbon atoms will eventually be released on later turns of the cycle; thus, all six carbon atoms from the original glucose molecule are eventually incorporated into carbon dioxide. Each turn of the cycle forms three NADH molecules and one FADH2 molecule.
Where is oxygen gas produced during photosynthesis?
All photosynthetic eukaryotic cells contain chloroplasts that use the radiant energy of sunlight to convert carbon dioxide and water into carbohydrates. As a byproduct of photosynthesis, oxygen gas is also released into the atmosphere through tiny openings in the leaves called stomata.
How is oxygen produced during photosynthesis?
During the light reactions, an electron is stripped from a water molecule freeing the oxygen and hydrogen atoms. The free oxygen atom combines with another free oxygen atom to produce oxygen gas which is then released.
When and how is oxygen released as a by product in the photosystem?
The light excites an electron from the chlorophyll a pair, which passes to the primary electron acceptor. The excited electron must then be replaced. In (a) photosystem II, the electron comes from the splitting of water, which releases oxygen as a waste product.
