B2a-c 5.0 / 5 based on 1 rating ? BiologyMicrobes and diseaseGCSEOCR Created by: notae003Created on: 17-05-15 00:25 What are the 5 kingdoms? Plants, animals, fungi, protoctista and prokaryotes. 1 of 16 What are the 5 kingdoms further classified into? Kingdom, phylum, class, order, family, genus and species. 2 of 16 What is artificial classification? The classification of organisms based on physical characteristics. 3 of 16 What is natural classification? The classification of organisms based on evolutionary links, so organisms are grouped together by common ancestory. 4 of 16 What is a species? A group of similar organisms that can interbreed to produce fertile offspring. 5 of 16 What is the binomial system? A system that identifies all species by a two-part Latin name (the first part = genus and the second part = species). 6 of 16 Name two organisms that are difficult to classify. Whales/dolphins and mules. 7 of 16 What is a pyramid of numbers? A diagram that shows how many organisms feed at each trophic level. 8 of 16 What is a pyramid of biomass? A diagram that shows the dry mass of organisms feeding at each trophic level. 9 of 16 Name a producer of a food chain. Plants. 10 of 16 Roughly how much energy is transferred from one trophic level to the next? 10%. 11 of 16 Give three ways that energy is lost at each stage of the food chain. Excretion, maintaining body temperature and respiration. 12 of 16 Name two types of decomposers. Bacteria and fungi. 13 of 16 Give the three conditions needed for decomposition. Oxygen (for microbial respiration), moist and a suitable temperature. 14 of 16 Why is it difficult to construct a pyramid of biomass? Because you have to kill the organisms to calculate dry mass. 15 of 16 How do you calculate the efficiency of a food chain? energy at next level / energy at previous level x 100% 16 of 16
