B2 2.5 0.0 / 5 ? BiologyAdaptations of organisms to their environmentGCSEAQA Created by: HarryLewisCreated on: 17-09-16 10:03 The distribution of organisms is affected by what? Environmental factors 1 of 8 Since plants provide food for animals what does fewer plants in an area often mean? Fewer animals 2 of 8 Why might temperature effect the distribution of organisms in an area? In cold places the plants are small which means limited numbers of plant eaters can live in that area. 3 of 8 Why might the availability of nutrients effect the distribution of organisms in an area? Plants struggle to grow in an area of few mineral ions and so the number of plant eaters is limited. 4 of 8 Why might the amount of light effect the distribution of organisms in an area? Plants need light to photosynthesise so there wouldn't be many plants in a shaded area. 5 of 8 Why might the availability of water effect the distribution of organisms in an area? Plants and animals need water to live so if there is no water there will be no organisms. 6 of 8 Why might the availability of oxygen effect the distribution of organisms in an area? All organisms need oxygen so if there is a lack of oxygen no organisms will live there. 7 of 8 Why might the availability of carbon dioxide effect the distribution of organisms in an area? Lack of carbon dioxide will effect plant growth and also the number of animals. 8 of 8
