Bio Test Flashcards
Ecology
The study of how organisms interact with one another and their environment
Hierarchical Organization of Ecology
Biosphere (Florida), Ecosystem (Everglades), Community ( animals in the everglades), Population (all alligators in the area), Organism ( American Alligator)
Ecosystem
A community of living organisms interacting with their environment
Autotroph (Producer)
produces own food
Heterotroph (Consumer)
Must consume food
Decomposer
breaks down dead material for food
Trophic Levels/rule
10% transfer
Competition
For resources, land, often detrimental to both organisms.
Predation/Parasitism
Beneficial to one organism, harmful to another.
Mutualism
The interaction is mutually beneficial to both organisms.
Commensalism
One species benefits, the other is not affected.
Evolutionary Adaptation
Adaptations evolve over many generations as individuals with traits best suited to their environments have greater reproductive success and pass their traits to offspring.
Binomial System
The first part, the genus, is the closest group to which a species belongs.
The second part, the specific epithet, refers to one species within each genus.
The first letter of the genus is capitalized and both names are italicized and latinized.
For example, Linnaeus assigned to humans the scientific name Homo sapiens, which means “wise man,” perhaps in a show of optimism.
What is the difference between Eukaryotic and Prokaryotic cells?
Organisms in the domain Bacteria and Archaea are prokaryotes. Organisms in domain Eukarya are eukaryotes. Prokaryotic cells are smaller and simpler. Eukaryotic cells are larger and more complex.
Linnean System Hierarchy
Domain, Kingdom, Phylum, Class, Order, Family, Genus, Species. Do keep pets clean or flies spread.
Domain Archaea
Made of prokaryotic cells. Kingdom is Archaebacteria.
Domain Bacteria
Made of prokaryotic cells. Kingdom is Eubacteria.
Domain Eukarya
Made of eukaryotic cells. Kingdoms are Protista, Fungi, Plantae, Animalia
