Symbiotic relationship
Close relationship between two or more species that can be beneficial and/or harmful to the organisms
Environment
Conditions, such as air and temperature, that an organism is surrounded by
Community
Made of of all the organisms of all the different species that are in a specific geographic area
Ecosystem
Is made up of the community and its abiotic factors
Abiotic factors
Nonliving factors found in the environment that have an influence on the organism
Subdivisions of an environment in order from smallest to largest
Organism, community, ecosystem, biosphere
Triggers ecological succession
Natural occurrences and human activity
Ecological succession
The gradual change of ecosystems over a period of time
What is included in the natural selection theory
Individuals within species are variable, well adapted individuals have more offspring, survival and reproduction are not random and the species who survive are favorable.
Natural selection
The agent responsible for determining the differential rate of reproduction
The type of symbiotic relationship that occurs when insects get food from, and simultaneously pollinate, flowers
Mutualism
Organism
Living thing that responds to environment, grows and reproduces
Amensalism
Relationship between two organisms where one species is killed and the other is not affected
