| A | B |
| The way that organisms interact with their environment | ecology |
| Everything that affects an organism during its lifetime | environment |
| All the non-living factors that affect an organism | abiotic |
| The major abiotic factor would be the ... | sun |
| All the living forms of life that affect an organism | biotic |
| The one primary condition in an environment that determines the success or failure | limiting factor |
| What is the limiting factor for many aquatic organisms | amount of dissolved oxygen |
| Type of very tolerant fish | carp |
| The space that an organism inhabits | habitat |
| Everything that affects or is affected by an organism | niche |
| The total role an organism plays in its habitat | niche |
| Process that determines which individuals within a species will reproduce and survive | natural selection |
| Explained the process of natural selection | charles darwin |
| The fact that twins are different is because of this idea of natural selection | All organisms show variation because of genes |
| Those organisms lowest on the food chain would use this idea of natural selection | Organisms produce more offspring than can survive |
| Blind animals not surviving well, are explained by this idea | Different genetic make-ups make some organisms better |
| Good survival genes being passed is because of this idea | Organisms that survive pass on their traits |
| A group of organisms that can interbreed and produce fertile offspring` | species |
| Fertile means | able to reproduce |
| Process of developing a new species is called | speciation |
| Process of gradual change in a species | evolution |
| Occurs when 1 kind of animal kills and eats another | predation |
| Animal that kills another animal | predator |
| Animal that is killed by another animal | prey |
| Which benefits the most from predation...predator or prey | both |
| A kind of interaction in which 2 or more organisms strive for the same resource | competition |
| Competition occurs between organisms of different species | interspecific |
| Competition between organisms of the same species | intraspecific |
| A close physical relationship between 2 organisms | symbiosis |
| Interaction between organisms in which one lives on or in another | parasitism |
| Organism that lives off another | parasite |
| Organism that is harmed by a parasite | host |
| Parasites that live on the surface of a host | ectoparasite |
| Parasites that live in a host | endoparasite |
| Occurs when 1 organism benefits and another is not affected | commensalism |
| When both species affected are benefited | mutualism |
| A place where groups of different organisms interact with each other | community |
| Responsible for having more species in an ecosystem | diversity |
| Organisms that use the sun for energy | producer |
| Organisms that rely on other organisms for their energy | consumers |
| Organisms that eat producers | primary consumers |
| Organisms that eat only plants | herbivores |
| Organisms that eat other animals | secondary consumers |
| Organisms that eat only meat | carnivores |
| Organisms that eat both plants and animals | omnivores |
| Consumers that eat non-living matter | decomposers |
| Each step in the food chain is called | trophic level |
| This shows the flow of energy between organisms | food chain |
| This shows the flow of energy within an ecosystem | food web |
| Process by which carbon is continously recycled | carbon cycle |
| Process by which nitrogen is continously recycled | nitrogen cycle |
| Process by which phosphorus is continously recycled | phosphorus cycle |
| This substance helps to build structures in cells such as DNA | phosphorus |
| This substance comes from rocks within the earth | phosphorus |
| This substance makes up 78% of the air | nitrogen |
| chemicals used to kill insects | pesticides |
| Using natural enemies to control pests and weeds | biological control |
| This substance is found in all living organisms | carbon |
| Biome | Certain physical environment determined by climate, temp, and precipitation |
| Tropical Rain forest | Contains more species than all other biomes combined |
| Tropical Dry forest | This biome has hot temp's with alternating wet and dry seasons |
| Tropical Savanna | Many tall grasses are found in this biome |
| desert | Receives less than 10" of rain per year |
| Temperate Grassland | This biome doesn't get enough rain to support tree growth |
| Temperate Woodland | This biome includes parts of California and Mediterranean Sea |
| Temperate Forest | Michigan is found in this biome |
| Northwest Confiferous Forest | This area is the lumber capital of the world |
| Boreal Forest | Also known as the Taiga |
| Tundra | Large regions of permafrost in this biome |
| permafrost | meaning that the ground is permenantly frozen |
| logistic growth | When a population's growth slows and stops when food and space become less available |
| carrying capacity | When an environment reaches the largest number of individuals it can support |
| immigration | Where individuals move into an area |
| emmigration | When individuals move out of an area |
| exponential growth | Occurs when a population's growth resembles a J shaped curve |
| Population | Group of organisms that belong to the same species and live in the same area |
| number of births | Factor that can affect population size |
| Number of deaths | Factor that can affect population size |
| Number of organisms entering or leaving | Factor that can affect population size |
| grow | A population will __________ if the birthrate is greater than the death rate |
| shrink | A population will __________ if the death rate is greater than the birth rate |
| Nitrogen fixing bacteria | Found in the roots of plants and convert atmospheric nitrogen to useful nitrogen |
