1. A producer is an organism that is capable of making its own food. For example, plants.

2. A consumer is an organism that cannot make its own food and hence fed on producers or other consumers. E.g humans

3. A predator-prey relationship is a relationship in which a predator organism eats a prey organism. For example, lion and zebra.

4.  Symbiosis is a biological interaction between organisms of different species.

5. Parasitism is a biological interaction in which one organism gains benefit and harms the other organism.

6. Commensalism is a biological interaction in which one organism gains benefit whereas the other organism neither gets harmed nor gains any benefit.

7. Mutualism is a biological interaction in which both the organisms benefit from each other.

8. A niche is the role which an organism plays in a community or an ecosystem.
