What do animals need to survive in an environment?(4) | • Space • Food • Water • Mates |
What are different types of living factors?(4) | • Change in the number of infectious diseases • Change in the number of predators • Change in the number of prey • Change in the number of types of competitors |
What are different types of non-living factors?(3) | • Change in rainfall • Change in temperature • Change in air and water pollution |
What are the three main ways populations can change? | • Population increases • Population decreases • Population distribution changes |
Give an example of how population size could increase. | Number of prey increases-more food for predators-higher survival so more predator numbers increase too |
Give an example of how Population can decrease. | Number of prey decreases-less food for predators-lower survival because no food-predator numbers decrease |
Give an example of how population distribution can change. | A rise in temperature causes species from different environments to inhabit the area |
