Why Sun is ultimate source of energy for all living organisms?

Ans: The solar energy is very important to carry out the process of photosynthesis, it is captured by the leaves and stored in the plant in the form of food. And this in turn use by other organism to get food to obtain energy Thus, we say that sun is the ultimate source of energy for all living organisms.

Why is the sun is the main source of energy?

Solar radiation is the fundamental energy driving our climate system, and nearly all climatic and biologic processes on Earth are dependent on solar input. Energy from the sun is essential for many processes on Earth including warming of the surface, evaporation, photosynthesis and atmospheric circulation.

Which is ultimate source of energy?


What are the 3 things plants need to photosynthesize?

To perform photosynthesis, plants need three things: carbon dioxide, water, and sunlight.

What is the ultimate source of wind energy?

The sun

What is the ultimate source of energy for all living organisms Class 7?

Is Sun the ultimate source of energy for all living organisms?

The ultimate source of energy for all living organisms on earth is the ‘Sun’. Plants use the sun’s radiant energy to produce food by photosynthesis and in return store the food (chemical energy) in their fruits, stems, and roots. This form of stored energy is also known as biomass energy.

What organic compound is the main source of energy for living things?


Are lipids the main source of energy?

Lipids are an efficient source of energy (9kcal per gram) that the body stores in relative abundance. They also play an important role as building blocks for cell membranes, hormones, and physiologically active substances.

What is the main energy molecule of all living things?

Adenosine triphosphate (ATP), energy-carrying molecule found in the cells of all living things. ATP captures chemical energy obtained from the breakdown of food molecules and releases it to fuel other cellular processes.

Which of the following organic compounds is the richest source of energy?

Adenosine triphosphate ( ATP ) is the most important high-energy compound. It is a specialized nucleotide located in the cytoplasm of cells that serves as a source of cellular energy. ATP contains adenine (amino acid base ), ribose (sugar), and three phosphate groups.

How useful are organic compounds to humans?

Organic compounds essential to human functioning include carbohydrates, lipids, proteins, and nucleotides. Monomers are single units of organic compounds. They bond by dehydration synthesis to form polymers, which can in turn be broken by hydrolysis. Carbohydrate compounds provide essential body fuel.

What are compounds we use in everyday life?

List of Chemicals used in daily life

S:No Common name of the Chemical Molecular Formula and IUPAC name
3 Detergent Sodium sulphate, sodium hydroxide and phosphatecompounds
4 Toothpaste Calciuym carbonate, sodium flouride
5 Salt NaCl; Sodium Chloride
6 Vinegar C2H4O2 acetic acid, ethanoic acid

Can organic compounds be found in non living things?

Compounds isolated from nonliving systems, such as rocks and ores, the atmosphere, and the oceans, were labeled inorganic. For many years, scientists thought organic compounds could be made by only living organisms because they possessed a vital force found only in living systems.

How is ammonia converted to nitrite?

The first step is the oxidation of ammonia to nitrite, which is carried out by microbes known as ammonia-oxidizers. Aerobic ammonia oxidizers convert ammonia to nitrite via the intermediate hydroxylamine, a process that requires two different enzymes, ammonia monooxygenase and hydroxylamine oxidoreductase (Figure 4).

What are nitrates converted into?

In the fifth stage of the nitrogen cycle, nitrogen returns to the air as nitrates are converted to atmospheric nitrogen (N2) by bacteria through the process we call denitrification.

Why do plants need nitrates?

Plant roots absorb mineral salts including nitrates needed for healthy growth. For healthy growth plants need mineral ions including: – Nitrate for producing amino acids which are then used to form proteins. – Magnesium which is needed for chlorophyll production.
