Name: ______________________________________________________ SB4 – Ecology Unit Test Review Guide Students will assess the dependence of all organisms on one another and the flow of energy and matter within their ecosystem. SB4a. Investigate the relationships among organisms, populations, ecosystems, and biomes. 1 What is a group of organisms of the same species in an area? 2 What is a group of different species in an area? 3 What is an ecosystem? 4 We use different types of _____________________________to define different biomes. 5 Give 2 examples of biotic features. Give 2 examples of abiotic features. 6 What is an ecological niche? 7 Give an example of competition. 8 What is the difference between parasitism, commensalism, and mutualism? 9 What is the difference between random, uniform, and clumped dispersion? 10 What is a survivorship curve? a graph showing the number or proportion of individuals surviving to each age for a given species or group. Why are survivorship curves different for different organisms? 11 Logistic growth and Exponential growth show two different graph shapes. Draw the two different graphs and explain why they are different.
