From a structural point of view, all ecosystems consist of abiotic and biotic factors. Which of the following is a biotic factor of an ecosystem?

Correct option is D

​The correct answer is (d) Green plants.

Solution:

Ecosystems are made up of two major components:

1. Abiotic factors: These are the non-living physical and chemical components of the environment, such as temperature, light, soil, air, and water.
2. Biotic factors: These are the living components of the ecosystem, such as plants, animals, fungi, and microorganisms.

• Green plants are living organisms and are classified as biotic factors because they are involved in processes like photosynthesis, nutrient cycling, and interactions with other organisms in the ecosystem.

Explanation of Other Options:

•  Temperature: This is an abiotic factor, as it is a physical component of the environment that influences the ecosystem.
• Atmospheric humidity: This is an abiotic factor because it is a measure of moisture in the air, which affects the living conditions but is not a living entity.
• Carbon dioxide: This is an abiotic factor since it is a chemical component that influences processes like photosynthesis but is not living.

Information Booster:

Ecosystems, coined by Arthur Tansley in 1935, are dynamic systems where living organisms interact with their non-living environment.

• Role of Green Plants in Ecosystems:
• Green plants are producers in the food chain, converting sunlight into energy through photosynthesis.
• They form the base of most ecosystems and support all other trophic levels.
• Other Examples of Biotic Factors: Animals, fungi, bacteria, and decomposers.
