Answer:
1: Chemical Energy
2: Kinetic Energy
3: Electrical Energy
4: Mechanical Energy
Explanation:
1: The energy held in food is called chemical energy. It is a form of potential energy held within chemical bonds between atoms.
2: When flowing water is captured and turned into electricity, it is called hydroelectric power or hydropower. There are several types of hydroelectric facilities; they are all powered by the kinetic energy of flowing water as it moves downstream.
3: The power for lights and stuff is Electrical Energy, ofc :]
4: The chemical energy in the food gets changed into the mechanical energy of moving muscles.
Hope this helps!! :D
The correct options to the question will be:
Chemical energy.Kinetic energy.Electrical energy.Mechanical energy.It should be noted that the energy held in food is called chemical energy. It is simply a form of potential energy that is held within chemical bonds.
The energy of the wind or moving water is kinetic energy. The energy that powers out light is electrical energy while the energy that we use when we move around is mechanical energy.

What role have nitrates and phosphates played in damaging Muddy Creek?
Answer:
Nitrates and phosphates lead to eutrophication and anoxia in the creek which caused aquatic animals to die and damaged the creek.
Explanation:
Nitrates (NO3-) are chemical compounds that contain nitrogen and oxygen molecules. They are salts that are commonly found in fertilizers and are soluble in water. Phosphates are also compounds that are used in agricultural processes.
Nitrates and phosphate found in water are usually from plants that have been washed off by rain water and also from vehicles' exhaust.
When there are abnormally high levels of nitrates and phosphates in water, it becomes difficult for aquatic animals to survive. In bodies of water, the nitrates and phosphates become sources of food to algae and other plants, this causes them to become over stimulated, and lead to Eutrophication (a high concentration of nutrients) and Anoxia (lack of oxygen).
This causes the fishes to run out of oxygen and die. Then the water begins to change color (milky white or green), give off an offensive odor and gradually turns into a swamp and eventually a meadow
