A place where an organism lives and that provides the things the organism needs such as water, food, and shelter. Habitat
The living parts of an ecosystem such as plants and animals. Biotic
The non-living parts of an ecosystem such as water, sunlight, oxygen, temperature, and soil. Abiotic
Smallest functional and strucural unit of living organisms. Cell
A group of similar cells that perform a common function. Tissue
A group of similar tissues that perform a common funtion. Organ
A group of organs that perform a common function. Organ system
One living thing. Organism
One species. Population
Two or more species. Community
All the living and non-living. Ecosystem
A large region characterized by a similar type of climate and certain types of plant and animal communities. Biome
The part of earth where life exists. Biosphere
The study of how living things interact with one another and with their enviorment. Ecology
adds to a population. Birth rate
Leave a population Death rate
Moving into a population Immigration
Moving out of a population Emigration
Enviromental factor that prevents a population from increasing such as food, space, and weather. Limiting factors
Autotorphs, organisms that can make their own food. For example plants, algae, and some bacteria. Each food chain must start with a producer. Producer
Heterotrophs, cannot make their own food. Classified by what they eat. Consumers
Eat plants Herbivores
Eat meat Carnivores
Eat plants and meat Omnivores
A carnivores that feeds on the bodies of dead organisms. Scavengers
Organisms break down dead waste and dead organisms. Examples fungi, worms, and bacteria. Decomposers
a seris of events in which one organism eats another and obtains energy. The first organism in a food chain is ALWAYS a producer. Food chain
Many overlapping food chains in an ecosystem. Food web
Show the amount of energy that moves from one feeding level to another in a food web. The most energy is avaliable at the producer level. At each level, there is less avaliable energy than at the level below. Energy pyramid
The position that an organism occupies in a food web. Trophic level
An organisms particular role, or how it makes its living in an ecosystem. It includes the type of food the organism eats, how it obtains food, and which other species use the organisms for their food. Niche
The struggle between organisms to survive in a habitat with limited resources. Competition
Interaction in which one organism hunts and kills another for food. The hunter is the predator and the hunted is the prey the one eaten. Predation
A close relationship between two species where at least one benifits. Symbiosis
A close relationship between two species where one benifits and the other is neither helped nor harmed. + 0 relationship. Commensalism
A close relationship between two species where both benifit. ++ relationship. Mutualism
A close relationship between two species where one is helped and the other is harmed. +- relationship. Parasitism
The evolution of two species that is due to mutual influence, often in a way that makes the relationship beneficial to both species. Coevolution
The largest population that an enviroment can support at a given time. Carrying Capacity
Recycled in an ecosystem. Energy, on the other hand is not recycled. Matter
Process by molecules of liquid water absorb energy and change into the gas state. Evaporation
Process by which a gas changes into a liquid. Condesation
Water vapor condenses and drops back to earth in the form of rain, snow, hail, and sleet. Precipitation
The by which plants release water vapor into the air through stomata. Transpiration
Process of changing free nitrogen into a usable form. Bacteria that live on nodules on the plant's roots change free nitrogen into usable form in the process called nitrogen fixtion. Nitrogen cycle
