Producers are called producers because when they take in carbon dioxide and water, and they produce glucose and oxygen. Animals need oxygen to survive and producers are the reason that all of the animals on earth haven't used up all the oxygen in the atmosphere. We need producers to survive, otherwise the Earth would be carbon dioxide rich and we humans couldn't breath it.
An experiment or survey must be controlled in order to receive accurate results.
In an experimental group, the independent variable is changed. But in the control group, the independent variable stays the same.
You can use refraction which is the bending of light through a transparent material. Also the freezing and boiling points of water. One last one is the Cartesian five experiment, this shows the density of water. Hope this helped.
Answer:
In the light-independent reactions or Calvin cycle, the energized electrons from the light-dependent reactions provide the energy to form carbohydrates from carbon dioxide molecules.
Explanation:
After the energy is transferred, the energy carrier molecules return to the light-dependent reactions to obtain more energized electrons.
Answer:
• An acid is an electrolyte that hydrolyses in water to release hydrogen ions.

• pH level of an acid;
- Strong acid → 0 - 3.8
- Weak Acid → 4.0 - 6.7
