EVERYDAY SCIENCE

Detailed explanation-1: -Explanation: Biotic refers to all living things such as plants, animals, bacteria, fungi etc. Abiotic refers to all non-living parts of an ecosystem such as the sun, wind, soil, rain etc. So sunlight is an abiotic factor.

Detailed explanation-2: -Sunlight is the main source of energy on Earth, which makes it an extremely important abiotic factor. Sunlight is necessary for photosynthesis, the process by which plants convert carbon dioxide (CO2) and water to oxygen (O2) and sugar – food for the plants that later becomes food for animals.

Detailed explanation-3: -Hence the given statement is false.

Detailed explanation-4: -Abiotic means non-living components such as air, water, soil, light and temperature. From the above options, tree is a living component. So it is not an abiotic component.

Detailed explanation-5: -Sunlight plays an important role in the ecosystem. It is the primary source of energy, which is utilized by plants to produce food and is required for productivity and energy flow in the ecosystem. The visible spectrum of sunlight is used by plants for photosynthesis.
