Question

Which organisms are primarily responsible for fragmentation in the decomposition process?

Options

• Producers like green plants

• Detritivores, such as earthworms

• Consumers from higher trophic levels

• Bacteria and fungi only

Answer 1

Detritivores, with earthworms being a classic example, are the organisms that perform fragmentation. They physically break down detritus into smaller particles, which increases the total surface area available for further decomposition by bacteria and fungi. This is a critical first step in the decomposition pathway.
