What are 2 substances needed for 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 is the most important ingredient in photosynthesis?
The equation shows that the “ingredients” for photosynthesis are carbon dioxide, water, and light energy. Plants, algae, and photosynthetic bacteria take in light from the sun, molecules of carbon dioxide from the air, and water molecules from their environment and combine these reactants to produce food (glucose).
Which chemical is used in photosynthesis?
The process of photosynthesis is commonly written as: 6CO2 + 6H2O → C6H12O6 + 6O2. This means that the reactants, six carbon dioxide molecules and six water molecules, are converted by light energy captured by chlorophyll (implied by the arrow) into a sugar molecule and six oxygen molecules, the products.
What does HV stand for in photosynthesis?
Photosynthesis is the process of converting light energy (E = h v) to chemical energy and storing it in the chemical bonds of sugar-like molecules.
What is the main biological process that produces carbon dioxide?
cellular respiration
What are 3 activities that release carbon dioxide into the atmosphere?
A minor but very important component of the atmosphere, carbon dioxide is released through natural processes such as respiration and volcano eruptions and through human activities such as deforestation, land use changes, and burning fossil fuels.
What human activities increase greenhouse gases?
Humans are increasingly influencing the climate and the earth’s temperature by burning fossil fuels, cutting down forests and farming livestock. This adds enormous amounts of greenhouse gases to those naturally occurring in the atmosphere, increasing the greenhouse effect and global warming.
What are the six main human activities that produce the highest amount of greenhouse gases?
Answer:
- Carbon dioxide from the burning of fossil fuels is the largest single source of greenhouse gas emissions from human activities.
- Deforestation is the second largest source of carbon dioxide.
- Rice cultivation also releases methane.
- Domesticated animals emit methane.
