Topic: Ecology Aim: Describe the effect of limiting factors on populations. Do Now: Take out HW ditto HW: Ditto – Measurement Review SIDE 2 Which group contains only abiotic factors? Limiting • Anything that restricts factors the number of individuals in a population • Food, light, other living things When does • When 2 or more competition organisms seek same resource at the same occur? time • When they occupy the same niche Carrying • The largest # of capacity individuals of 1 species that an ecosystem can support over time What would happen if a population exceeds carrying capacity? • Population would be forced to move of die Although 3 different bird species all inhabit the same type of tree in an area, competition between the birds rarely occurs. The most likely explanation for this lack of competition is that these birds (1.) are unable to interbreed (2.) have a limited supply of food (3.) share food with each other (4.) have different ecological niches
