BiologyAdaptations of organisms to their environmentGCSEOCR Created by: RebeccaSharp1Created on: 28-03-16 17:40 define species a group of organisms that can breed to produce fertile offspring 1 of 26 who is Charles Darwin? a scientist who believed variation and inheritance causes evolution. 2 of 26 define adaptation characteristics or features of an organism that helps them to survive in their environment 3 of 26 define interdependence organisms in an environment that depend on each other for survival and compete with each other. 4 of 26 name four things that can cause extinction of a species? changes in climate, predators, disease and new species. 5 of 26 what do nearly all living species depend on? energy from the sun. 6 of 26 who is Lamarck? a scientist who believed organisms acquired characteristics in their lifetime and passed them on to their offspring 7 of 26 define habitat a place where an organism lives. 8 of 26 define decomposer microorganisms such as bacteria and fungi feed on dead r decaying organisms 9 of 26 define detitivore partly decayed material is called detritus. organisms such as woodlice and earthworms feed on detritus and break it down more. 10 of 26 define evolution species changing over time 11 of 26 name 2 types of nonliving factors that indicate a change in the environment CO2 levels and ice cores 12 of 26 define mutation a change in a species DNA 13 of 26 state three types of living indicator species phytoplankton, lichen, bloodworm, mayfly larvae 14 of 26 what happened 3.5billion years ago? it is thought that this is whne life on earth began. 15 of 26 define sustainability meeting the needs of people today without damaging earth for people of the future 16 of 26 define biodiversity the range of living species in an area. 17 of 26 what is classification? organisms are classified based on similarities and differences in characteristics and DNA 18 of 26 what happened 4500 million years ago? earth formed. 19 of 26 define 'common ancestor' a species that two or more species evolved from 20 of 26 why do we classify organisms? so that: 1) it allows us to look at evolutionary relationships 2) it allows scientists to figure out what new found organisms are 21 of 26 why is biodiversity important? 1) food crops can be developed from wild plants by selective breeding 2) many medicines come from wild plants and animals 22 of 26 name three important processes in the carbon cycle respiration, combustion and photosynthesis 23 of 26 which microorganism turns nitrogen into ammonia? nitrogen fixing bacteria 24 of 26 which microorganism turns ammonia into nitrates? nitrifying bacteria 25 of 26 what is the name of the soil bacteria that converts proteins and urea into ammonia? decomposers 26 of 26
