Studied by 1 personSpecies
Group of organisms that can potentially interbreed to produce fertile offspring
Autotroph
Organisms that produce their own food through obtaining inorganic nutrients from the abiotic environment (plants, some protoctista, some bacteria)
Heterotroph
Organisms that feed off of other organisms, hence obtains energy from outside sources (animals, fungi, some bacteria)
Producers
Autotrophs in tropic level 1
Consumers
Heterotrophs that feed on living organisms by ingestion (T2, T3, T4 etc)
Detritivore
Type of decomposer: heterotrophs that obtain organic nutrients from detritus by internal digestion (ex. earthworm, woodlice)
Saprotroph
Type of decomposer: heterotroph that obtain orgain nutrients from dead organisms by external digestion (ex. fungi, bacteria)
Community
Populations of different species living and interacting with each other
Population
All organisms of the same species in a particular area at a specific time
Ecosystem
Community of biotic and abiotic components of their environment, interacting as a system
Biotic factors
Living factors
Abiotic factors
Non-living factors
Nutrient cycling
A system where energy and matter are transferred between living organisms and non-living parts of the environment
Biosphere
Global ecosystem composed of living and non-living organisms, from which they derive energy and nutrients from
Habitat
Place where an organism lives; where it finds food, shelter and mates
Niche
An organisms role in the community and how it interacts with the environment; how it obtains food, mates, protection
Hybrids
Infertile cross-overs between 2 species (ex. mule, zorse, liger)
