The relationship between photosynthesis and respiration in terms of the reactants
Sample Solution
Photosynthesis and respiration are two complementary biochemical processes that occur in all living organisms. Photosynthesis is the process by which plants use sunlight, water, and carbon dioxide to produce oxygen and glucose. Respiration is the process by which all living organisms use oxygen to break down glucose and produce energy.Full Answer Section
The reactants and products of photosynthesis and respiration are as follows:
Photosynthesis:
- Reactants: sunlight, water, carbon dioxide
- Products: oxygen, glucose
Respiration:
- Reactants: oxygen, glucose
- Products: water, carbon dioxide, energy
Relationship between photosynthesis and respiration
Photosynthesis and respiration are closely related processes. The oxygen produced by photosynthesis is used by all living organisms for respiration. The glucose produced by photosynthesis is used by plants for energy and is also eaten by other organisms, which then use it for energy through respiration.
Asteroid impact theory
The asteroid impact theory is a scientific theory that proposes that an asteroid impact caused the Cretaceous–Paleogene extinction event, which killed off the dinosaurs and many other species. The theory is based on the evidence of a large impact crater that was discovered in the Yucatán Peninsula in Mexico.
The asteroid impact theory is supported by a number of other lines of evidence, including:
- The presence of a layer of iridium-rich dust in the geological record that dates back to the time of the extinction event. Iridium is a rare element on Earth, but it is common in asteroids.
- The presence of shocked quartz in the geological record that dates back to the time of the extinction event. Shocked quartz is a form of quartz that is created when rocks are subjected to extreme pressure and heat.
- The presence of mass extinctions at other times in the geological record that are also associated with impact craters.
How the elimination of plants would affect virtually every ecosystem on the planet, our biosphere
Plants are the foundation of all ecosystems. They provide food and oxygen for all other living organisms. If plants were eliminated, virtually every other living organism on Earth would also die.
Plants play a number of important roles in ecosystems, including:
- Providing food for other organisms
- Producing oxygen
- Filtering water
- Preventing soil erosion
- Regulating the climate
The elimination of plants would have a devastating impact on all ecosystems on the planet. It would lead to the extinction of many species, including humans.
Conclusion
Photosynthesis and respiration are two complementary biochemical processes that are essential for life on Earth. The asteroid impact theory is a scientific theory that proposes that an asteroid impact caused the Cretaceous–Paleogene extinction event, which killed off the dinosaurs and many other species. The elimination of plants would have a devastating impact on all ecosystems on the planet.
