What is a community in ecological terms?

Groups of populations of different species living and interacting in a habitat.

A natural unit of biotic and abiotic components interacting.

Define the term 'wave' in a scientific context.

What happens when a wave breaks at the shore?

The water at the top moves faster than the bottom and crumbles.

What are tsunamis and how are they caused?
