MD Biology Chapter 4.2, 4.3, 5.1 & 5.2 Vocabulary
| Question | Answer |
|---|---|
| Ability of an organism to survive and reproduce under circumstances that differ from their optimal conditions. | tolerance |
| Area where an organism lives, including the biotic and abiotic factors that affect it. | habitat |
| Full range of physical and biological conditions in which an organism lives and the way in which the organism uses those conditions. | niche |
| Any necessity of life, such as water, nutrients, light, food, or space. | resource |
| Principle that states that no two species can occupy the same niche in the same habitat at the same time. | competitive exclusion principle |
| Interaction in which on organism captures and feeds on another organism. | predation |
| Interaction in which one animal feeds on producers. | herbivory |
| Single species that is not usually abundant in a community yet exerts strong control on the structure of a community. | keystone species |
| Relationship in which two species live close together. | symbiosis |
| Symbiotic relationship in which both species benefit from the relationship. | mutualism |
| Symbiotic relationship in which one organism lives on or inside another organism and harms it. | parasitism |
| Symbiotic relationship in which one organism benefits and the other is neither helped or harmed. | commensalism |
| Series of gradual changes that occur in a community following a disturbance. | ecological succession |
| Succession that occurs in an area in which no trace of a previous community is present. | primary succession |
| First species to populate an area during succession. | pioneer species |
| Type of succession that occurs in an area that was only partially destroyed by disturbances. | secondary succession |
| Number of individuals per unit area. | population density |
| Number of males and females of each age in a population. | age structure |
| Movement of individuals into an area occupied by an existing population. | immigration |
| Movement of individuals out of an area. | emigration |
| Growth pattern in which the individuals in a population reproduce at a constant rate. | exponential growth |
| Growth pattern in which a population's growth slows and then stops following a period of exponential growth. | logistic growth |
| Largest number of individuals of a particular species that a particular environment can support. | carrying capacity |
| Factor that causes population growth to decrease. | limiting factor |
| Limiting factors that depends on population density. | density-dependent limiting factor |
| Limiting factors that affect all populations in similar ways, regardless of the population density. | density-independent limiting factor |
