| Ecosystem | living and nonliving things together including populations and communitites |
| Biota | Living |
| Abiota | non-living |
| Population | One type of organism in a space |
| Organism | A single living thing |
| Community | More than one type of organism in a space |
| Scientific Method | Set of steps scientists take |
| Limiting Factors | Keeps populations from reaching carrying capacity |
| Commensalism | one partner benefits while the other is unaffected |
| Multualistic | both species benefit |
| Parasitic | one partner benefits while the other is negatively affected |
| Predator/prey | one partner eats while the other is eaten |
| Producers | gets its energy from the sun |
| Primary consumers | get its energy from the producer |
| Secondary consumer | gets its energy from the primary consumer |
| Tertiary consumer | gets its energy from the secondary consumer |
| Carrying capacity | largest population that an area can support |
| Exponential growth | a population that is multiplying out of control |
| Overpopulation | result of the lack of limiting factors |
| Succession | a set of predictable changes in an ecosystem |
| Primary Succession | series of changes that occur in an area where no ecosystem previously existed. |
| Secondary Succession | changes that occur after a disturbance. |
| Pioneer species | first species to populate area. |
| Ask a question | First step of scientific method |
| Gather Information | Second step of scientific method |
| Make Hypothesis | Third step of scientific method |
| Form procedures to test hypothesis | Forth step of scientific method |
| Test Hypothesis | Fifth step of scientific method |
| Analyze test results | Sixth step of scientific method |
| Make a conclusion/accept or reject original hypothesis | Final step of scientific method |
| habitat | The place where an organism lives and that provides the things the organism needs is called its |
| symbiosis | A close relationship between two species that benefits at least one of the species is called |
| Population density | the number of individuals of a population in a specific area. |
| adaptation | characterists of a species thay allow them to live successfully in their environment |
| food chains | a series of events in which one organism eats another |
| food webs | overlapping food chains together |
