The interaction of a community of a living organism. 1 of 25 What is a Population? All the organisms of one species living in one habitat. 2 of 25 What are Abiotic Factors? Non-living factors of the environment. 3 of 25 What are Biotic Factors? Living factors of the environment. 4 of 25 What is a Community? The population of different species living in a habitat. 5 of 25 Why do animals have pale colouring? This would reflect sunlight, so this would allow them to keep cool. 6 of 25 Why do animals have few skin pores? These let moisture out, so if you have few, you'll save water. 7 of 25 Why do animals have wide feet? Prevents sinking. 8 of 25 Why do animals have small limbs/ears? To keep heat in. 9 of 25 What are examples of Biotic factors? New preadtor, competition, new pathogens and availability of food. 10 of 25 What are examples of Abiotic factors? Moisture level, light intensity, carbon dixoide level, wind intensity, oxygen level, Soil pH and mineral count. 11 of 25 What are four things animals compete for? Food, water, mate and land. 12 of 25 What are four things plants compete for? Water, light, space and minerals & nutrients. 13 of 25 What are the largest groups?

Area x Mean 21 of 25 Calculate the mean number of species in one quadrat? Total / Number of Quadrats. 22 of 25 How do you make testing with Quadrats more accurate? Place randomly, Use more Quadrats, Repeat and use bigger quadrats. 23 of 25 What is a transect line? Can be made using a rope marked & numbered at 0.5 or 1m intervals. 24 of 25 Why is a transect line used? To see how many species are in that area and to spot a pattern. 25 of 25
