How human get energy?
Humans get energy primarily from the food they eat. The body breaks down carbohydrates, fats, and proteins from food into energy through a process called metabolism. This energy is used to fuel various bodily functions such as movement, digestion, and brain activity.
What is energy efficiency and how efficient is the human body?
Energy efficiency refers to the ratio of useful energy output to the total energy input in a system. The human body is approximately 25% energy efficient, with the remaining 75% of energy being dissipated as heat. This efficiency can vary depending on factors such as metabolic rate and activity level.
What determines how much energy a human can receive from?
A human gets energy from the calories of food. how much energy the food molecules have
How much heat does a human being generate?
On average, a human body generates around 100 watts of heat energy while at rest, with the brain accounting for about 20% of that heat production. During physical activity, this heat production can increase significantly depending on the intensity of the activity.
Why do you need to store energy in your bodies?
We store energy in our bodies to use it. Every movement in our body, including simple things like raising our hands require energy. Without energy, we would not be able to do anything. In order to make it more 'convenient', without having to consume food or drinks when we need energy, we store energy in our bodies so that we can use it when we need it.
Why do you need to have breakfast?
The human body needs food energy to work properly, and breakfast provides the nutrition that you need for physical and mental activity. It is especially important in children because they are using energy and food for growth.
Why do need to have breakfast?

How do you get the energy you need for physical activity?
carbohydrates
Energy requirements of phyiscal activity?
for diffrent types of activities you need diffrent energy types and for that energy you need protien.
What human activity does not affect earth system?
Breathing. Except that respiration needs Energy.
Which human activity has the greatest impact on increasing mercury levels?
burning coal for energy
What is the need of sports?
Sports meet two human needs, the need to compete, and the need for physical activity.
How do human muscle cells use lactic acid fermentation to produce energy during intense physical activity?
During intense physical activity, human muscle cells use lactic acid fermentation to produce energy when there is not enough oxygen available. This process converts glucose into lactic acid, releasing energy that can be used by the muscles for short bursts of activity.
Is human a heterotroph?
YesA human is a heterotoph, they are consumers.They cannot make energy from sunlight, so they need to consume other organisms to get the energy they need.
Can human action cause weathering?
human is living things human has live human can reproduce human need energy human need water and food human can grow
What are the 5 uses of energy in the human body?
The five main uses of energy in the human body are for metabolism, physical activity, maintaining body temperature, growth and development, and cellular processes.
Human activity uses as much energy as all of earth's other multicellular species combined?
True
