Which level of the food chain includes millipede, springtails, woodlice, dung flies and slugs that feed on the dead or decaying plants or animals?

Detritivores

The correct answer is Option (2)- Detritivores

The level of the food chain that includes millipedes, springtails, woodlice, dung flies, and slugs that feed on dead or decaying plants or animals is composed of Detritivores.

Detritivores:

• Detritivores are organisms that obtain their nutrients by consuming dead or decaying organic matter, such as plant material, animal remains, or feces.
• They play a crucial role in the decomposition process, breaking down organic material into simpler compounds and facilitating nutrient recycling in ecosystems.
• Examples of detritivores include millipedes, springtails, woodlice, dung flies, and slugs, as mentioned in the question.

In contrast:

• Carnivores: Feed on other animals.
• Omnivores: Consume both plants and animals.
• Herbivores: Feed on plant material.

Detritivores, by feeding on dead and decaying matter, contribute to the decomposition and nutrient cycling within ecosystems.
