Question

1. All the organisms derive energy from A) Soil B) Water C) Air D) Food​

Answer 1

Answer:

The physical and biological world where we live in - Environment/biosphere

Each level of food chain where transfer of energy takes place - Trophic level

The physical factors like temperature, rainfall, wind and soil of an ecosystem - Abiotic factors

Organisms which depend on the producers either directly or indirectly for food - Consumers/heterotrophs

Therefore, the correct answer is option B.

Answer 2

The Correct Solution is Option D, Food.

• The Sun is the primary source of energy.
• Plants and algae, for example, use sunlight to create food energy by combining carbon dioxide and water to build organic matter.
• Almost all food webs begin with this mechanism, which starts the flow of energy.
• All life processes are powered by the stored energy in food.
• Food is made up of organic molecules that serve as a source of energy and building material for all living things.
• Carbohydrates, lipids, and proteins, as well as organic acids, polyols, and ethanol in the diet, provide energy to organisms.
• Food molecules are broken down, allowing cells to store energy and carry out the many operations of the cell, and thus the entire organism.
• The food absorbed by the organisms proceeds via cellular respiration, which releases energy.
• Mitochondria are known as the cell's powerhouses.
