BiologyAdaptations of organisms to their environmentGCSEAQA Created by: naomi2310Created on: 05-01-15 18:35 In what ways have arctic animals adapted to reduce heat loss? Small surface area compared to volume, well insulated, camouflage 1 of 21 How are desert animals adapted to their conditions? (4 things) Large Surface Area compared to volume, efficient with water, good in hot conditions, camouflage 2 of 21 How are desert plants adapted to having little water? Small surface area compared to volume, water storage tissues, maximizing water absorbtion 3 of 21 How do plants and animals deter predators? Some plants and animals have armor, others produces poisons, some have warning colours 4 of 21 What are 'extremophiles'? Microorganisms that live in extreme conditions e.g hot volcanic lakes 5 of 21 Give three examples of living factors. change in infectious disease, number of predators/prey, number of competitors 6 of 21 Give three examples of non living factors. change in temperature, rainfall, air or water pollution 7 of 21 What do plants compete for? light, water, space and minerals from the soil 8 of 21 What do animals compete for? territory, food, water and mates. 9 of 21 Give three examples of environmental changes Population size increases, decreases or distribution changes 10 of 21 What are living indicators, can you give an example? Living indicators/indicator species can be studied to see the effect of human activities. Lichen 11 of 21 What are non living indicators, can you give an example? An example of a non living indicator is a satellite, which measures the temperature of the sea surface. 12 of 21 What do lichen do? Lichen measure the concentration of sulfur dioxide in the atmosphere. If the air is clean there is lots of lichen 13 of 21 What does each bar of a pyramid of biomass show? The mass of living material at that stage of the food chain. 14 of 21 What elements do plants take in from the soil or air? Carbon, oxygen, nitrogen and hydrogen 15 of 21 What are detritus feeders? Animals which feed upon dead algae, plants and animal remains. 16 of 21 Which characteristics are due to Genes ONLY? Blood Type, Eye Colour, Inherited Disorders 17 of 21 What is the order in size in genetic material? (largest to smallest) Nucleus, 23 Pairs of Chromosomes, Gene, DNA Molecules 18 of 21 What do Genes Do? Control the development of different characteristics e.g Hair Colour 19 of 21 How many chromosomes do Gametes have? 23. Half the number of a normal cell. 20 of 21 What is asexual reproduction? No fusion of gametes, no mixing of chromosomes and no genetic information. They're clones. 21 of 21
