|---|---|
| Is a place where an organism lives and that provides the things that an organism needs | Habitat |
| Are the living parts of an ecosystem | Biotic Factors |
| Are the non-living parts of an ecosystem | Abiotic Factors |
| What are the 5 different abiotic factors found in most ecosystems | Water, Sunlight, Oxygen, Temperature, and Soil |
| All the members of one species in a particular area | Population |
| All of the different populations that live together in an area | Community |
| The study of how living things interact with each other and the environment | Ecology |
| The number of individuals in a specific area | Population Density |
| Getting the exact number. | Direct Observation |
| Giving an estimate. Using techniques such as sampling,and mark and recapture. | Indirect Observation |
| What are two ways that populations can increase | -A population can increase because of a higher birth rate that a death rate -A population can increase because of a higher immigration rate than an emigration rate |
| What are two ways that populations can decrease | -A population can decrease because of a higher death rate than a birth rate -A population can decrease because of a higher emigration rate than an immigration rate |
| A limiting factor where animals will die of starvation | Food |
| A limiting factor where organisms cannot produce fertile offspring. | Space |
| A limiting factor where the organisms are at risk for the temperatures and natural disasters. | Weather |
| An organism that can create its own food | Producer |
| An organism that obtains its energy by feeding on other organisms | Consumer |
| An organism that only eats plant | Herbivore |
| An organism that only eats meat. | Carnivore |
| An organism that eats both meat and plants | Omnivore |
| An organism that is a carnivore, but only eats the meat of dead animals. | Scavenger |
| A series of events in which one organism eats another and obtains energy | Food Chain |
| Consists of overlapping food chains in an ecosystem | Food Web |
| All of the living an non-living thing that interact in a particular area | Ecosystem |
| A group of ecosystems with similar climate and organisms | Biome |
| The two climatic conditions that determine an areas biome | Temperature and Rainfall |
| Not that much warm temperatures*Is very wet and humid*The greatest amount of species in any other biome | Tropical Rain Forest |
| Receives more than 300 centimeters of rain a year *Has a lot of trees*Has moderate temperatures | Temperate Rain Forest |
| Is hot during the day time*Is very dry*Organisms are adapted to extreme temperatures and dry conditions | Desert |
| Receives around 25 to 75 centimeters of rain each year*Is populated by grass and many large herbivores | Grassland |
| -Has warm summers Cold winters with heavy snow*Receives at least 50 centimeters of rain per year*Trees shed their leaves and grow new ones each year | Deciduous Forest |
| Has warm, rainy summers*Very cold winters with heavy snow*Tress provide cones with seeds that are eaten by many animals | Boreal (Taiga) Forest |
| Very cold winters*Warmer summers. Is windy, very dry, no trees, and low-growing plants | Tundra |
