Colonies: A group of organisms living together, individuals in the group are not physiologically connected and may not be related, such as a colony of birds. Another meaning refers to organisms, such as bryozoans, which are composed of numerous genetically identical modules (also referred to as zooids or 'individuals'), which are produced by budding and remain physiologically connected.
Steppe: A biome (or subdivision of the Earth's surface) that is composed of a swathe of temperate grassland stretching from Romania to China. In Africa this lies in the transition zone between savanna and severe desert.
