Species | A group of organisms that can mate with each other and produce offspring that can also mate and reproduce. |
Population | Members of one species living in a particular area. |
Community | All the different populations that live together in an area. |
Ecosystem | The community os organisms that live in a particular area, along with their nonliving environment. |
Ecology | The study of how organisms interact with each other and there environments. |
Immigration | Moving into a population |
Emigration | Leaving a population |
Population Density | The number of individuals in an area os a specific size (number of individuals/unit area) |
Limiting Factor | An environmental factor that causes a population to stop growing or decrease in size (ex. weather conditions, space, food, and water) |
Carrying Capacity | The largest population that an area can support. |
Niche | The role of an organism in its habitat. |
Competition | The struggle between organisms to survive as they attempt to use same limited resources. |
Symbiosis | A relationship in which two species live closely together and at least one of the species benefits. |
Mutualism | A relationship in which both species benefits. |
Commensalism | A relationship in which one species benefits and the other species is neither helped nor harmed. |
Parasitism | A relationship that involves one organisms living with, on, or inside an organism and harming it. |
Species - Sentence | Scientists are still finding new SPECIES of animals today. |
population - Sentence | When animals get hit by cars it decreases the POPULATION of the species in that area. |
Ecosystem - Sentence | ECOSYSTEMS are mostly in forests or wide ranges of land. |
Ecology - Sentence | Im thinking about studying ECOLOGY for my science project this year. |
Immigration - Sentence | When the days get colder the animals know its IMMIGRATION season. |
Emigration - Sentence | EMIGRATION is when an organism wants to leave the "community" to move to another. |
Population Density - Sentence | The POPULATION DENSITY determines the amount of organisms in that area. |
Limiting Factor - Sentence | When weather conditions are bad and other problems are repeatedly going on in the community the organism might refer to a LIMITING FACTOR. |
Carrying Capacity - Sentence | The CARRYING CAPACITY determines the amount of people or organisms you can have in that area. |
Niche - Sentence | Each group of organisms has a NICHE in its habitat. |
Competition - Sentence | The animals were having a COMPETITION to see who could get to the food the fastest. |
Symbiosis - Sentence | Fish and reefs have a good SYMBIOSIS. |
Mutualism - Sentence | Flowers and bees have perfect MUTUALISM. |
Commensalism - Sentence | Birds hanging out on cows backs is a great example of COMMENSALISM. |
Parasitism - Sentence | The owl benefits from the chipmunk by eating it so they have a PARASITISM. |
