Answer
| Amensalism | Parasitism | Competition | |
| 1 | It is an interspecific interaction in which one is harmed and the other is neither benefitted nor harmed. | It is an interspecific interaction in which one species, called parasite takes shelter and food from another living organism, called host and in due course of time damages the host. | It is a type of interaction either among the individuals of same species (intraspecific), or between individuals of different species (interspecific), for the same resources. |
| 2 | Neither of the partners is benefitted. | One of the partners is benefitted. | None of the partners is benefitted. |
| 3 | Example: Antibiotics secreted by certain fungi kill some bacteria in the vicinity. | Example: Cuscuta living on the hedge plants. | Example: flamingoes and fishes competing for food (zooplanktons) in a lake. |
- Predation is the interspecific interaction in which a larger animal (predator) kills and consumes a smaller animal (prey) or an animal (herbivore) eats a plant as food.
