A detritivorus animal of economic importance is
- Giriraja fowl
- Earthworm
- Leech
- Caterpillar larva
The Correct Option is B
Approach Solution - 1
Approach Solution -2
Explanation:
- Detritivores are organisms that feed on dead and decaying organic matter. From the given options, the animal that holds economic importance is the earthworm.
- Earthworms are considered very helpful to farmers in many ways, such as improving soil quality. Here are some of the benefits of earthworms for soil:
1. As earthworms dig through the soil, they create passages that help air and water circulate. This helps plant roots get the oxygen they need to grow.
These tunnels also help improve the excess water seeping into the soil.
2. Earthworms consume dead plants and animal matter, which breaks it down into smaller pieces. This organic matter can provide nutrients to plants.
3. Earthworm castings, or poop, are a nutrient-rich fertilizer that helps plants grow.
- Thus, the right answer to this question is an earthworm.

Concepts Used:
Ecosystem
An ecosystem is a structural and functional unit of ecology where the living organisms come in to interact with each other and the surrounding environment.
Structure of the Ecosystem:
The structure of an ecosystem is distinguished by the organization of both biotic and abiotic components. This involves the distribution of energy in our environment. It also comprises the climatic conditions prevailing in that particular environment.
There are two main components of the structure of an ecosystem, namely:
- Biotic Components
- Abiotic Components
The biotic and abiotic components are interconnected in an ecosystem. It is an open system where the energy and components can flow through the boundaries.
