Which two types of substances are needed in a humans diet for energy?
Carbohydrates and fats are the two types of substances needed in a human diet for energy. Carbohydrates are the body's main source of energy, providing quick fuel for muscles and the brain. Fats are also important for energy storage and providing a slower, long-lasting source of energy.
What important substances do plants produce during photosynthesis How do humans use these substances?
Plants produce glucose and oxygen during photosynthesis. Humans use glucose as a source of energy through the food we eat, while we rely on the oxygen produced by plants for respiration.
What 2 substances are necessary for combustion to occur?
Two substances necessary for combustion to occur are fuel (such as wood, gas, or oil) and oxygen. The fuel provides the energy source, while oxygen acts as the oxidizer that allows the fuel to burn.
What is the process that uses light energy to make new substances that have chemical energy?
The process is called photosynthesis. It occurs in plants, algae, and some bacteria, where they use light energy to convert carbon dioxide and water into glucose and oxygen. This process is vital for life on Earth as it provides the energy source for most living organisms.
What provides energy for cells by using oxygen is called?
Cellular respiration is the process that provides energy for cells by using oxygen. It involves breaking down glucose molecules to produce ATP, the cell's main energy source.
What substance provides humans with their main source of energy?
Carbohydrates are the main source of energy for humans. When consumed, carbohydrates are broken down into glucose, which our cells use to produce ATP (adenosine triphosphate) - the energy currency of the body.
Why is photsynthesis important to humans and animals?
It provides basic energy source and life on Earth

Does fiber have sugar and provides quick energy?
Fiber is made of glucose molecules arranged into a starch(cellulose), so they are not a quick source of energy. Humans have difficulty digesting fiber.
Which energy source provides us with the most energy?
Wind
What important substances do plants produce during photosynthesis How do humans use these substances?
Plants produce glucose and oxygen during photosynthesis. Humans use glucose as a source of energy through the food we eat, while we rely on the oxygen produced by plants for respiration.
What energy source releases harmful substances?
nuclear
What energy source changes a substances temperature?
Friction
Our food provides a source of what?
Nutrients and energy.
Identify the primary source of energy for humans?
The primary source of energy for humans is food, which provides the body with essential nutrients and calories to power various bodily functions and activities. The body converts the energy from food into ATP (adenosine triphosphate) through metabolic processes, which is used for cellular energy.
Which renewable energy source provides the US with the most energy?
Hydropower
When the sun provides a clean source of energy its known as what?
solar energy
