Which process in photosynthesis uses energy from the sun
1. splitting water into hydrogen and oxygen
2. carbon dioxide
3. usable form of energy
4. Heat
5. 6
6. Photosynthesis converts radiant energy to chemical energy to be used by organisms in the food chain.
7. Living organisms decay, releasing carbon into the soil, and soil is compacted into rocks.
8. bacteria
9. nitrogen fixation, nitrification, and denitrification.
10. Energy flows in one direction, and matter cycles through the environment.
11. Food webs are the best depictions of feeding relationships because they show many ways that plants and animals are connected.
12-14 do on ur own
Those are the right answers, i promise.
SasukeFangirl is 100% correct!
ok ty
is he right??
sasuke is right
The process in photosynthesis that uses energy from the sun is called the light-dependent reactions. Here's how you can explain it:
1. Photosynthesis is the process by which plants convert sunlight, water, and carbon dioxide into glucose (a type of sugar) and oxygen. It occurs in the chloroplasts, which are located in the cells of plants.
2. Within the chloroplasts, there are pigments called chlorophyll, which are responsible for capturing the energy from sunlight. The main pigments involved are chlorophyll a and chlorophyll b.
3. The process begins when light energy is absorbed by chlorophyll in the chloroplasts. This energy is then used to split water molecules into hydrogen ions (H+), electrons (e-), and oxygen (O2). This step is called photolysis.
4. The electrons that are released by water during photolysis are then transferred through a series of protein complexes in a process called electron transport chain. This movement of electrons generates ATP (adenosine triphosphate), which is a molecule that stores energy.
5. As the electrons pass through the electron transport chain, they lose energy. This energy is used to pump hydrogen ions (H+) across the thylakoid membrane, creating a concentration gradient.
6. The accumulated hydrogen ions flow back across the thylakoid membrane through a protein channel called ATP synthase. This flow of hydrogen ions powers the production of ATP, which is the primary energy currency of cells.
7. The energy-rich ATP molecules produced during the light-dependent reactions will be utilized in the next stage of photosynthesis, called the light-independent reactions (also known as the Calvin cycle). It is during this stage that carbon dioxide is used to produce glucose.
Overall, the light-dependent reactions in photosynthesis capture energy from sunlight, convert it into chemical energy, and produce ATP. This energy is then used in the light-independent reactions to synthesize glucose, which is essential for plant growth and survival.
