Answer:
Electricity flows by the movement of electrons through conductors. If a bird perches on a wire with two feet there is no motivation to go through the birds' body so electrons choose the path of least resistance and continue to flow along the wire.
Explanation:
Answer:
The correct answer is - a- They convert energy from the sun to chemical energy.
Explanation:
Producers in any food web or ecosystem are the organism that can produce the food and energy on their own. Normally these organisms are green plants that can perform photosynthesis in order to produce chemical energy from light energy that comes from the sun.
Producers not only provide food and energy to themselves but also provide food and energy to each trophic level directly or indirectly. Producers are present at the base of the energy pyramid.
Answer:
The more calories a food has, the more energy it can provide to your body. When you eat more calories than you need, your body stores the extra calories as body fat.
Dietary fats are essential to give your body energy and to support cell growth. They also help protect your organs and help keep your body warm. Fats help your body absorb some nutrients and produce important hormones, too.
Carbohydrates are your body's main source of energy: They help fuel your brain, kidneys, heart muscles, and central nervous system. For instance, fiber is a carbohydrate that aids in digestion, helps you feel full, and keeps blood cholesterol levels in check.
The structure and function of our bodies depend on proteins. The regulation of the body's cells, tissues, and organs cannot happen without them. Muscles, skin, bones, and other parts of the human body contain significant amounts of protein, including enzymes, hormones, and antibodies.
Explanation:
Answer:
The events occurring in the light reaction of the photosynthesis are: Absorption of sunlight by the chlorophyll and release of the electron to the carriers. Photolysis of water to provide the electron to the chlorophyll. The release of molecular oxygen due to the photolysis of water.
