Types of heterotrophs: 1 Mark each
Green plants can sometimes be heterotrophic.
The different types of heterotrophs are parasites, symbionts, saprophytes, and insectivores.
Any two:
1. Parasitic plants obtain their nourishment from other living organisms. Example: mistletoe.
2. Symbiotic plants develop a special relationship with certain other organisms to obtain nourishment. This type of arrangement is beneficialto both the organisms involved. Example: lichens.
3. Saprophytic plants which feed on dead or decaying organic matter. Theysecrete digestive juices onto dead and decaying matter to break it and then absorb nutrients from it. Example: coral roots.
4.Insectivorous plants have leaves that are modified into special structures which have the ability to trap small organisms like insects. The plant then derives the nutrition from the insect by slowly digesting it. Example: Venus flytrap.
