| Question | Answer |
|---|---|
| who was Darwin | a British naturalist |
| where was darwin's famous journey | the galapagous |
| what is fitness | related to how well your genes make it into the next generation |
| how are survival and reproduction linked | they are both needed for fitness |
| what is the difference between convergent and divergent evolution | convergent - evolve similar characteristics divergent - evolve independently |
| what are darwin's 4 pieces of evidence for evolution | 1. fossil record 2. homologous body structures 3. similarities in embryology 4. geographical distribution of living species |
| what is natural selection and an example of it | natures selections for or against an organism because of their characteristics |
| what is the difference between natural selection and artificial selection | natural selection - nature selects artificial selection - humans select |
| what is taxonomy | scientific names for animals |
| what is the correct way to write a scientific name | capitalize genus but not species, underline when writing and italicize |
| what are the 3 domains | archaea ,bacteria and eukarya |
| name the 4 kingdoms and give an example of each | protista - protozoans fugi - mushroom plantae - multicellular plants animalia - multicellular animals |
| what is a dichotomous key | characteristics given in pairs |
| what benefits to using a dichotomous key | it helps break down the results to identify a specific organism ones looking for or go to another one |
| what is the order of the ecological hierarchy of an organism | individual- population - community - ecosystem -biosphere |
| what are two biotic factors | plants and animals |
| what are two abiotic factors | rocks and soil |
| what is the difference between exponential and logistic growth | exponential is when a population grows at a steady rate each year. while logistic growth is an ideal conditions with unlimited resources |
| what is a niche | special role and place of an organism withing its habitat |
| can two species occupy the same niche at the same time | no because its only made for one organism |
| define mutualism | both species benefit from interaction |
| what is an example of mutualism | pollination |
| define commensalism | relationship in which one organism benefits while other is unaffected |
| what is an example of commensalism | barnacles on whales |
| define amensalism | relationship in which one organism is harmed while the other is unaffected |
| what is an example of amensalism | squishing a spider |
| define parasitism | relationship in which one organism benefits while the other is harmed |
| what is an example of parasitism | tapeworms |
| define predation | process by which individuals of one species capture kill and consume individuals of another species |
| what is the difference between a producer and consumer | producer - make there own food consumer - obtain energy from eating another organism |
| what is a herbivore | organisms that eat only plants |
| what is an example of a herbivore | girrafe |
| what is a omnivore | organism that eats both plant and animals |
| what is an example of an omnivore | humans |
| what is a carnivore | organism that eats only animals |
| what is an example of a carnivore | cheetah |
| what is a detritivore | organism that eats dead things or waste |
| what is an example of detritivore | volchures |
| what is a decomposer | organism that breaks down nonliving things |
| what is an example of a decomposer | mushroom |
| why is only 10% of the energy gets passes on to the next level | the rest is lost as heat, waste or unedible |
| what is the difference between primary and secondary sucession | primary eliminates all vegetation and/or soil life while secondary doesn't destroy all local organism |
