Symbiosis
What is symbiosis?
A close relationship and often long-term interaction between two different biological species.
What is competition?
When organisms of the same or different species attemps to use an ecological resourse in the same place at the same time.
What are the 3 factors in Competition?
Physical factors, Biological factors amd behavior.
What is a niche?
The way in which am organism uses its surroundings (both abiotic and biotic).
Its like their job.
What is ecological succession?
A series of more-or-less predictable canges that occur in a commmunity over time.
What are the three types of symbiotic relationships?
Commensalism, Mutualism, and Parasitism.
What is predation?
Interactions in which on organism captures and feeds on another organism.
What is a physical factor?
Range of physical factors for survival and reproduction: temperature, humidity, pH, sunlight, space, etc.
What is fundimental niche?
A niche of a species includes the total range of enviornmental conditions that are suitable for existance without the influence of interspecific competition or predation from others.
What is primary succession?
A type of ecological succession in which plants and animals colonize a barren area. There is no soil. Usually happens after a volcanic eruption.
What is mutualism?
A type of symbiotic relationship in which both the host and the guest organism benefit from the relationship in some way.
What is Herbivory?
Interactions in which one animal (the herbivore) feeds on producers (such as plants).
What is a biological factor?
What is realized niche?
A niche defined for a species that includes where the organism lives and the resources it can access as a result of limiting pressures from other species (competition).
What is secondary succession?
A type of ecological succession in which plants and animals recolonize a habitat after a major disturbance. Soil remains. Easier for vegitation to re-grow. It is faster than primary succession.
What is commensalism?
A type of symbiotic relationship in which one organism benefits from the host without causing benefits it nor harm to it.
What is a prey? What is a predator?
A predator is an animal that naturally preys on others. A prey is an animal that is killled by another for food.
What is behavior?
Seaasonality, diurnal patterns, movement, social organization, etc. An organisms behavior will further define its niche.
What is a habitat?
A habitat is the place an organism lives including its abiotic and biotic surroundings.
What is a pioneer species?
The first organism to colonize during ecological succession.
What is parasitism?
A type of symbiotic relationship between species where one species, the parasite, benefits at the expense of the other, the host.
Describe the role competition plays in shaping a community.
Since competition makes species to divide resources, it helps determine the amount and types of species in a community and the niche each species occupies.
What is the Competative Exclusion Principle?
An ecological rule that states that no two species can occupy the same exact niche in the same habitat at the same time.
What is a keystone species?
A keystone species is a species on which other species in an ecosystem largely depend on it, such that if it were removed, the ecosystem would change drastically.
What is a climax community?
An ecological community in whoch populations of plants or animals remain stable and exist in balance with each other in their enviornment.
