The place where an organism lives 1 of 34 What is an enviroment? The surroundings of an organism 2 of 34 Give examples of non-living factors light, dampness, temperature etc. 3 of 34 Non-living factors that affect an enviroment are called...? Physical enviromental factors 4 of 34 Living things that affect an enviroment are called...? Living factors 5 of 34 All the *blanks* and *blanks* that live in a habitat make up a community plants and animals 6 of 34 The total number of one species is called a...? Population 7 of 34 In order to photosynthesize (make food), what do plants need? Light, water, CO2, nutrients, oxygen, space 8 of 34 Scientists who study habitats are called...? Ecologists 9 of 34 a *blank* is a sampling square used to measure plant population Quadrant 10 of 34 What does a pyramid of numbers show? The population of organisms at each level in the food chain 11 of 34 A solid is soluble when...? It can dissolve in a liquid, making a solution 12 of 34 a solute (solid) and a solvent (liquid) make a...? Solution 13 of 34 When a solution is formed, the liquid is always transparent. True or false? True 14 of 34 How can you tell if a solid is insoluble? If it is mixed with water, the water will go cloudy 15 of 34 the total mass of a solution equals...? The mass of the solvent, added to the mass of the solute 16 of 34 What is a solvent? a liquid 17 of 34 What is a solute? a solid 18 of 34 A saturated solution cannot do what? Dissolve any more solute. However, more solute WILL dissolve if you add more solvent or increase the temperature 19 of 34 What are some examples of solvents? Water, white spirit, ethanol 20 of 34 What is temperature measured in? Degrees Celsius (c) 21 of 34 What is heat/thermal energy measured in? Joules (J) 22 of 34 What is conduction? Conduction takes place in solids. it can also take place in liquids, but not very well. Metals are the best conductors. 23 of 34 What is an insulator? Something that doesn't conduct heat very well 24 of 34 Where does convection take place? In fluids 25 of 34 What is a fluid? A fluid is a liquid or a gas 26 of 34 *blank* *blank* can transfer heat energy through empty space, as it doesn't require particle movement. Infared radiation 27 of 34 Any hot or warm object *blank* radiation, and when something takes in heat energy from radiation, it is said to *blank* it. Emits, absorbs 28 of 34 In what way is infared radiation similar to light? it can be absorbed, reflected and focused 29 of 34 The temperature of a substance does not change while it is melting, even if it is stlii being heated. True or false? True 30 of 34 What are the seven food groups? Carbohydrate, protein, fat, vitamin, mineral, fibre and water 31 of 34 How could you test for starch in a food? by using iodine solution, starch makes it go a black-blue colour 32 of 34 What are enzymes? Chemicals that break up food 33 of 34 There are *blank* known elements 117 34 of 34
