Question | Answer |
An interaction between 2 or more individuals for the same resources. | competition |
The study of the way organism interact with each other in their surroundings. | ecology |
Nonliving factors in the environment. | abiotic factors |
An organism that only consumes other animals. | carnivore |
Intersecting and overlapping food chains. | food web |
A parasite that is adapted to live within a host. | endoparasite |
Favorable characteristics passed on that change an organism over time to make them more adapted to their region. | evolution |
These cause the decay of organic matter and recycle nutrients. Ex. Bacteria and Fungus | decomposer |
An accumulation of organic material produced by living things. | biomass |
Identifiable region in which a particular kind of organism lives. | habitat |
The death of a species-total elimination. | extinction |
Interacting groups of different species. | community |
Organism adapted to live on the outside of its host. | ectoparasite |
Cyclic flow of carbon from the atmosphere to living organisms and back. | carbon cycle |
Bacteria that converts nitrogen compound into nitrogen gases. | denitirifying bacteria |
Living organisms in an environment. | biotic factors |
Eat plants and is considered a primary consumer. | herbivore |
A series of organisms involved in the passage of energy from one trophic level to the next. | food chain |
Everything that effects an organism in its lifetime. | environment |
Organisms that rely on other organisms for food. | consumer |
A group of interacting species and the physical environment around them. | ecosystem |
Relationship where one organism benefits and the other is not affected. | commensalism |
Organic material that results from fecal waste material or the decomposition of plants and animals. | detritus |
Bacteria living in the soil and can convert nitrogen gas in the atmosphere into forms plants can use. | Free-living Nitrogen fixing bacteria |
An organism that lives in or on another organism. | parasite |
Population of organisms who can interbreed and produce fertile offspring. | species |
Shortage or absence of a key factor restricts the success of the species. | limiting factors |
The functional role of an organism in its surroundings. | niche |
These organisms make new, complex, organic material from the atoms in the environment. | producers |
Bacteria that are able to convert the nitrogen gas in the atmosphere. | nitrogen-fixing bacteria |
Each step in the flow of energy through an ecosystem. | trophic level |
Where parasites get their nourishment. | host |
Competition between members of the same species. | intraspecific competition |
Close, long lasting, physical relationship between two different species. | symbiosis |
The flow of nitrogen atoms through organisms in an ecosystem. | nitrogen cycle |
Competition between members of a different species. | interspecific competition |
A relationship between two organisms where both are benefitted. | mutualism |
Production of a new species from a previously existing species. | speciation |
Process of more successful individuals surviving and reproducing large numbers of offspring over time. | natural selection |
These organisms get their nutrition by eating plants. They are also known as Herbivores. | primary consumers |
An animal that hunts for its prey for food. | predators |
This is a relationship between two organisms where one organism benefits at the expense of another. | parasitism |
An organism that not only eats plants but animals as well. | omnivore |
These consumers eat primary consumers and some will eat producers. | secondary consumers |
These organisms are fed upon by predators. | prey |
Bacteria that lives in nodules in the roots of plants known as legumes. | symbiotic nitrogen-fixing bacteria |
The ability of an organism to succeed under a variety of environmental conditions. | range of tolerance |
