Thus, regions of the world with similar climates have similar biomes. For example, a bird that feeds on the forest floor during the day but roosts within the canopy.

Certain organisms may be more reliant on the presence of others to fulfill their nutritional requirements, for example insects that can feed only from one species of plant. The organisms in this biome can tolerate the extreme conditions.

The interaction supplies the coral with energy and the algae with nutrients; however, the algae only remain within the body under certain temperatures. However, the most important factors that determine the distribution of forest and savanna are climatic factors. Communities at tropical latitudes tend to display high species richness and diversity, due to the high productivity of plants, which receive large amounts of solar energy, and have year-round climatic stability.

Since the development of the steel plow, however, most have been converted to agricultural fields. The savanna zone is made up of mainly grasses and is further sub-divided into three savanna belts or biotic communities which are: Communities consist of a group of different species, which partake in direct and indirect biotic interactions, such as predator-prey interactions, herbivory , parasitism , competition and mutualisms.

The complexity of the interactions between species signifies the delicate balance within communities. The main savanna region is in Africa.

Many of such interactions may take place only under precise environmental conditions. For instance, in a forest, a dominant tree species may control amount of light available to other plants, the temperature in the lower canopy, and the nutrients that are available to other organisms, whilst their reproduction may depend on pollination by a rare insect.
