Decomposers with Varying Relations
Some decomposer organism’s cannot be assigned a rigid or fixed position in the food
web. Their trophic relations can vary from time to time.
- Nectroph: Some decomposers are nectrophs. They cause rapid death of the food
source because they have a short-term exploitation of living organism. Nectrophs
include may plant parasitic microbes as well as some herbivores, predators, and
microtrophs (organisms which feed on living bacteria and fungi.) - Biotrophs: On the other hand biotopes resort to a long-term exploitation of their
living food resource. For example, root-feeding nematodes and aphids, obligate
plant parasites, e.g., and mycorhizae and root nodules, etc. - Saprotophs: The apostrophes utilize food already dead, and most of the decomposers
belong to this category.
