Select the biotic component of an ecosystem from the following :

Question

Accepted Answer

In an ecosystem, components are broadly classified into biotic and abiotic components. Biotic components refer to the living parts of an ecosystem, which include organisms such as plants, animals, fungi, and microorganisms. Abiotic components, on the other hand, are the non-living physical and chemical elements in the environment, such as sunlight, soil, water, and minerals.

Option 2, "Planktons," is the correct answer because planktons are living organisms found in aquatic environments. They are a crucial part of the food chain and play a significant role in the ecosystem by providing food for a wide range of marine animals, including fish and whales. Planktons are classified as biotic components because they are living entities that interact with other organisms within the ecosystem.

Now, let's examine why the other options are incorrect:

1. Chlorophyll: Chlorophyll is a pigment found in plants that is essential for photosynthesis, the process by which plants convert sunlight into energy. While chlorophyll is a vital component of plant cells, it is not a living organism itself. Therefore, it is not considered a biotic component but rather a part of the plant's cellular structure.

3. Sunlight: Sunlight is an abiotic component of an ecosystem. It is a form of energy that is crucial for the survival of many living organisms, particularly plants, which use it for photosynthesis. However, sunlight itself is not a living entity, so it does not qualify as a biotic component.

4. Soil: Soil is a complex mixture of minerals, organic matter, gases, liquids, and countless organisms that together support life on Earth. While soil contains living organisms such as bacteria and fungi, the soil itself is considered an abiotic component because it is primarily composed of non-living materials.

In conclusion, Option 2, "Planktons," is the correct choice as the biotic component of an ecosystem because planktons are living organisms that play a vital role in aquatic ecosystems. The other options, while important to ecosystems, are not living entities and therefore do not qualify as biotic components.
