AP Biology Period – 4 Liem Nguyen #22 Rimsha Ahmed #3 Saumya Singhal #29 Ivan Pachev #23 Sindhur Rao #26 Nikolai Reichert #27 4/16/10 Homework #50 (090424): Chapter 50 (due Tuesday 090424) Total points: 40 for Attempt on all questions (Bullet Points) (Individual) Concept Map: 10 Points (Group) Chapter 50: An Introduction to Ecology and the Biosphere Objectives The Scope of Ecology 1. Define ecology. Identify the two features of organisms studied by ecologists. Study of interactions between organisms and environment Where do they live Why do they live where they do How many are there Ecology is the study of the interactions between organisms and their environments. Two features of the organisms studied by ecologists are where they live, and why they live there. Ecologists also study how many organisms are in that location. 2. Describe the relationship between ecology and evolutionary biology. Close relationship Numbers Population Genetics Evolution There is a close relationship between ecology and evolutionary biology. Ecology mostly deals with the numbers part of biology, for example, how much of an organism is where and etc. This relates to evolutionary biology because these population changes affect the genetics (gene pool) of a population of organisms. In this way, ecology can help predict evolutionary changes. 3. Distinguish between abiotic and biotic components of the environment. Abiotic- nonliving Biotic- living Biota

In every environment, there must be abiotic components. These abiotic components are nonliving chemical and physical factors such as temperature, light, water, and nutrients. The biotic factors of an environment include all the living things called biota in an environment. These biotic factors rely on the abiotic factors for survival. 4. Distinguish among organismal ecology, population ecology, community ecology, ecosystem ecology, and landscape ecology. Organismal- morphology, physiology, behavior Population- population density, distribution, age, structure, etc Community- how species affect community structure and organization Ecosystem- energy flow, cycling of chemicals Landscape- past, present, future patterns of landscape us. Organismal ecology studies the morphological, physiological, and behavior traits of organisms in their environment. Population ecology studies population density, distribution, age, structure, etc. Community ecology studies how species affect community structure and organization. Ecosystem ecology studies energy flow and the cycling of chemicals throughout and environment. Landscape ecology studies the past, present, and future patterns of landscape us and ecosystem management and the biodiversity of interacting ecosystems. 5. Clarify the difference between ecology and environmentalism.
