What is the main source of energy for animals?
carbohydratesThe primary source of energy for animals is carbohydrates primarily glucose: the body’s fuel. The digestible carbohydrates in an animal’s diet are converted to glucose molecules and into energy through a series of catabolic chemical reactions. Adenosine triphosphate or ATP is the primary energy currency in cells.

The SunThe Sun is Earth’s primary source of energy.
Why plants are called as the main source of food on earth?
The leaves have a green pigment called chlorophyll which helps leaves to capture the energy of the sunlight. This energy is used to synthesise (prepare) food from carbon dioxide and water. Question 5: Show with the help of a sketch that the plants are the ultimate source of food. See also what is an encyclopedia entry
What is the main source of solar energy?
Answer: The main source of solar energy is the SUN. Energy is produced by nuclear fusion in the core region through a series of steps called the p–p (proton–proton) chain in the surface of the sun this process converts hydrogen into helium and massive light and heat energies.
Which of the following is the primary source of all food on earth?
Plants and animals are the main source of food for all the organisms on earth. Food obtained from animals is the main source of protein and include fish milk meat poultry and cheese. Whereas plants provide us with fruits and vegetables which are an important source of fibres proteins and carbohydrates.

What is the ultimate source of energy in food?
The sunAll food relationships allow for energy to be passed through an ecosystem. The sun is the ultimate source of energy. In an ecosystem the greatest energy is stored at the producer level. See also what is another word for boundary
What are the 2 main sources of Earth’s energy?
Two sources provide more than 99 percent of the power for our civilization: solar and nuclear. Every other significant energy source is a form of one of these two. Most are forms of solar. When we burn wood we release previously captured solar energy.
What Is The Source Of All Food Energy On Earth?
The Sun is the major source of energy for organisms and the ecosystems of which they are a part. Producers such as plants and algae use energy from sunlight to make food energy by combining carbon dioxide and water to form organic matter. This process begins the flow of energy through almost all food webs.
Which energy can be used by all organisms?
ATP in Metabolism. ATP produced by glucose catabolized during cellular respiration serves as the universal energy currency for all living organisms.
How plants are ultimate source of food on earth?
As they are produce food by the process of photosynthesis which cannt be done by anyother else. Solar energy is ultimate energy in the earth from which green plants make their food and provides to other to maintain food chain in our ecosystem. … Hence plants are the ultimate soyrce of food on earth.
How is the sun the source of all energy on Earth?
The Sun is the Ultimate Source of Energy. Every morning the sun rises bringing light and heat to the earth and every evening it sets. … Plants convert light energy from the sun into chemical energy (food) by the process of photosynthesis. Animals eat plants and use that same chemical energy for all their activities.
What is the ultimate source of energy for all living organisms Class 7?
sunThe solar energy is captured by the leaves and stored in the plant in the form of food. Thus sun is the ultimate source of energy for all living organisms.
What is the main source of all energy?
the sun
One of the most important sources of energy is the sun. The energy of the sun is the original source of most of the energy found on earth. We get solar heat energy from the sun and sunlight can also be used to produce electricity from solar (photovoltaic) cells.
What is the only source of energy for all ecosystems on Earth?
The SunThe Sun is the major source of energy for organisms and the ecosystems of which they are a part. Producers such as plants and algae use energy from sunlight to make food energy by combining carbon dioxide and water to form organic matter. This process begins the flow of energy through almost all food webs. See also why did the world plunged into ww2 in 1939
