Community Interactions One of the foundational understandings of ecology as a whole is that organisms in a community are all interacting with each other constantly in one way or another. Community interactions such as competition, predation, and various forms of symbiosis, can powerfully affect an ecosystem. One of the foundational understandings of ecology as a whole is that the organisms in a community are all interacting upon each other constantly. Community interactions such as ______________, ___________________, and various forms of _______________________, will powerfully shape an ecosystem. Every organism has a role that it fulfills. In essence, it could be understood as the way in which it makes a living—its method of gaining the resources that it needs in order to ultimately grow and reproduce. This is the idea of a ____________. The niche of an organism involves: ____________________________________ _________________________________________________________________

Community interactions Every organism has a role that it fulfills—each organism has a way in which they get the resources that they need in order to survive. This is the idea of a niche. The niche of an organism involves all of the physical and biological conditions that the organism lives in, and the way in which it uses those conditions.

Competition In nature, ecosystems often can be limited in the amount of a resource that is available. If two organism in the same community attempt to use the same resource, competition occurs. Competition: If two organisms in a community attempt to use an ecological resource in the same place at the same time, _____________ occurs. In nature, direct competition for the same resource can often lead to a clear ‘____________’ and a clear ‘____________,” with the loser failing to survive. In ecology, there is a basic premise which states that no two organisms can occupy an identical niche in the same habitat at the same time. This is called the ________________ __________________________________. List an example of competition:

Competition: In nature, there is often a clear winner and loser in cases of direct competition. The loser will fail to survive if it remains in the same niche. In ecology, we have a basic knowledge which states that no two organism can occupy the same niche in the same habitat at the same time. This is called competitive exclusion. If two organisms in a community attempt to use an ecological resource in the same place at the same time, _____________ occurs. In nature, direct competition for the same resource can often lead to a clear ‘____________’ and a clear ‘____________,” with the loser failing to survive. In ecology, there is a basic premise which states that no two organisms can occupy an identical niche in the same habitat at the same time. This is called the ________________ __________________________________.

Predation An entire food web is filled with many examples of predator-prey relationships. In an ecosystem, an organism could be a predator on an organism in a lower trophic level, while being the prey of an organism in the next highest food level. Prey Predator

Symbiosis Sometimes in a community, there are examples of organisms of two different species living in an intentional relationship with each other. We call this a symbiotic relationship. Symbiotic relationships can be categorized into three different groups; Mutualism Commensalism Parasitism

Mutualism: A relationship in which both organisms are benefitted. Insects move from flower to flower, gathering their nectar, which the use as an energy source. The flowers benefit from the insects by being pollinated. Nitrogen-fixing bacteria and leguminous plants.

Commensalism: A relationship in which one organism is benefitted, and the second organism isn’t affected.

Parasitism: A relationship in which one organism is benefitted, and the second organism is harmed
