Document Summary

Marine ecology: ecology is the interaction between organisms and their environment, these interactions affect the survival and distribution of these organisms, population. Ways that species can interact: competition, predator-prey interactions. Outcomes of interspecific competition: one species excludes the other (principle of competitive exclusion, they coexist (resource partitioning by sharing a resource, or by becoming specialized (eating a particular food, feeding at different times, etc. ) Facultative symbiosis- if partners can live free without one another: obligate symbiosis- if a partner can"t survive without the other partner. In all cases the smaller partner is known as the symbiont and the larger partner is known as host. Predation: one species (predator) kills another (prey) for food. Prey species often have adaptations that help them avoid being eaten such as warning coloration, camouflage, and mimicry: herbivory, an organism (herbivore) that eats seaweeds and plants.

Shawnta used several terms in her post that I want to be sure everyone understands. Ecology is studied with a hierarchy, similar to the hierarchy of classification. The lowest level is the individual. A group of individuals of the same species that live in the same area is called a population. All of the different populations that live in the same area make up a community. So far we have only been talking about the living organisms. When you add in the non-living components of an area you have an ecosystem. The living parts of an ecosystem are called the biotic components and the non-living parts are called the abiotic components.
What are some of the abiotic components that affect what can live in an ecosystem?
