Document Summary
Species are connected with one another, and their environment (study of ecology) Although so far we have considered species interactions in two-way relationships, in reality, species experience multiple interactions that shape the communities in which they live. Communities are groups of interacting species that occur together at the same place and time. The existence of a community is dependent on the individual species that are present and how they interact with one another and their physical surroundings. These interactions are synergistic meaning that the effect of multiple interactions together is greater than the sum of their separate effects. In practical terms, ecologists usually define communities based on physical or biological characteristics. A physically defined community might encompass all the species in a sand dune, a mountain stream, or a desert. (defined by physical characteristics of environment) Desert, hot spring (biomes and aquatic biological zone are largely based on physical characteristics)
