There are six types of biotic interaction:
- Mutualism – It means both species benefit. For example – Pollination.
- Commensalism – It means one species benefits and the other is unaffected. For example – Cow dung provides food and shelter to dung beetles.
- Amensalism – It means one species is harmed and the other is unaffected. For example – A large tree Shades a small plant. Here the small tree is harmed and the large tree is unaffected.
- Predation and Parasitism – It means one is benefited and the other is harmed. For example – Man eats fish.
- Competition – Under this, both species are harmed by the interaction.
- Neutralism – It means no benefit or harm to either species.
