| Question | Answer |
|---|---|
| Tropical rainforest | warm temperature and abundant rainfall, lush think forests |
| Grassland | warm summers with a dry season and a rainy season. Tall grasses with scattered trees |
| Desert | Almost no rain fall. Vegetation store water of have deep root systems |
| Temperate frost | hot in simmer and cold in winter precipitation spaced evenly over the year mainly deciduous trees |
| Taiga | long cold winters and coniferous trees |
| Tundra | very cold most of the year very little precitation ground is permanently frozen and mosses and low lying plants survive |
| Density dependent factor | Increasing population size reduces available resources limiting population growth |
| Density independent factor | A factor that affects the size of a population independent or regardless of the population density. |
| predator/prey relationship | A predator is an organism that eats another organism. The prey is the organism which the predator eats |
| intraspecific competition | competition between organisms of the same species |
| symbiosis | competition between organisms of different species |
| parasitism | long-term interaction between two or more different biological species |
| Commensalism | relationship in which one organism benefits and the other is harmed |
| Mutualism | a relationship in which one organism benefits and the other is neither harmed or helped |
| Terrestrial succession | a relationship in which both organisms benefits |
| pioneer species | A series of regular, predictable changes in the structure of a community over time. |
| climax community | first species to inhabit an area and are often fast growing plants that can tolerate full sun |
| primary succession | occurs when succession slows down and stable community is established |
| secondary succession | when succession occurs in an area completely lacking vegetation and soil |
| aquatic pond succession | when succession occurs in an area after an ecological disturbance like a forest fire |
| competition | A geological event, such as a glacier or sink hole, can create a pond |
| predation | a contest between organisms , animals , groups |
| symbiosis | an animal that is hunting (finding its prey) |
| succession | predictable change in the sequence of species that established in a particular area over time |
| photosynthesis | process used by plants and other autotrophic organisms to convert light energy |
| mitochondria | membrane-enclosed organelle found in most eukaryotic cells |
| chloroplast | organelles found in plant cells and some other eukaryotic organisms |
| cellular respiration | metabolic reactions and processes that take place in the cells of organisms to convert biochemical energy from nutrients |
