Which of the following is a biotic component of ecology?

Fungi

The correct answer is Option (4)- Fungi

Fungi is a biotic component of ecology.

Explanation:

Biotic components in ecology refer to living organisms or the effects of living organisms on the environment. Fungi, being living organisms, are considered biotic components. They play essential roles in ecological processes, such as decomposition, nutrient cycling, and symbiotic relationships with other organisms. In contrast, abiotic components, like sunlight, carbonic substances, and humidity, are non-living factors that also influence ecological systems.
