- Biosphere - the part of the earth's crust, waters, and atmosphere that supports life.
Biosphere: where we are able to live
- Biome -a complex biotic community characterized by distinctive plant and animal species and maintained under the climatic conditions of the region, especially such a community that has developed to climax.
Biome: an area where similar animals can live
- Ecosystem - a system formed by the interaction of a community of organisms with their environment.
Ecosystem: what is left after animals and people haev been there
- Abiotic - of or characterized by the absence of life or living organisms.
- Biological Community
- Biological Community - A group of organisms that live closely together and form a natural ecologic unit.
Biological Community: a family of animals
- Population -
a.the assemblage of a specific type of organism living in a given area.
b.all the individuals of one species in a given area
Population # of similarly categorized organisms in one place
- Organism - any complex thing or system having properties and functions determined not only by the properties and relations of its individual parts, but by the character of the whole that they compose and by the relations of the parts to the whole.
Organism:anything whos basic unit of structure are cells
- Symbiosis - the living together of two dissimilar organisms, as in mutualism, commensalism, amensalism, or parasitism
Mutualism - a relationship between two species of organisms in which both benefit from the association
Mutualism: relationship where both are better off with each other
- Commensalism - (of an animal, plant, fungus, etc.) living with, on, or in another, without injury to either.
Commensalism: Relationship - not good but not bad
- Parasitism - a relation between organisms in which one lives as a parasite on another.
Parasitism: one lives on the other ad feeds off of him or her
- Predation - a relation between animals in which one organism captures and feeds on others.
Predation: animal eat animal
- Competition - the struggle between individuals of the same or different species for food, space, light, etc, when these are inadequate to supply the needs of all
Competion:fightong over resources
- Native Species
- Native species - A native species is an organism that is living in an area for entirely natural reasons, with no human intervention involved
Native Species: Original Animals to the area
- Invasive/exotic Species
- Invasive/exotic species - non-native (or alien) to the ecosystem under consideration
Invasive/exotic species:animals that arent originally from there but are there anyways
- Vector -
a.an insect or other organism that transmits a pathogenic fungus, virus, bacterium, etc.
b.any agent that acts as a carrier or transporter, as a virus or plasmid that conveys a genetically engineered dna segment into a host cell
Vector: disease carrier
- Habitat - the natural environment of an organism; place that is natural for the life and growth of an organism
Habitat: original home
- Niche - the position or function of an organism in a community of plants and animals
Niche: what an organism does
- Adaptation –
a.any alteration in the structure or function of an organism or any of its parts that results from natural selection and by which the organism becomes better fitted to survive and multiply in its environment.
b.a form or structure modified to fit a changed environment.
c.the ability of a species to survive in a particular ecological niche, especially because of alterations of form or behavior brought about through natural selection.
Adaptation: differences made to survive
- Trophic level
- Trophic level - any class of organisms that occupy the same position in a food chain, as primary consumers, secondary consumers, and tertiary consumers.
Trophic Level - group of organisms that eat at a certain time.
- Autotroph (producer) - any organism capable of self-nourishment by using inorganic materials as a source of nutrients and using photosynthesis or chemosynthesis as a source of energy, as most plants and certain bacteria and protists.
Autotroph - organism that makes its own food, usually plants
