Chapter 55: Ecosystems Ecosystems Ecosystem = sum of all the organisms living within its boundaries (biotic community) + abiotic factors with which they interact Involves two unique processes: Energy flow Chemical cycling Overview of energy & nutrient dynamics Energy Flow in an Ecosystem Energy cannot be recycled ? must be constantly supplied to an ecosystem (mostly by SUN) The autotrophs (?self feeders?) are the primary producers, and are usually photosynthetic (plants or algae). They use light energy to synthesize sugars and other organic compounds. Heterotrophs (?other feeders?) ? can?t make own food Heterotrophs are at trophic levels above the primary producers and depend on their photosynthetic output.

Chapter 54: Community Ecology Community = group of populations of different species living close enough to interact Interspecific interactions Can be positive (+), negative (-) or neutral (0) Includes: Competition (-/-) Predation (+/-) Herbivory (+/-) Symbiosis ? parasitism, mutualism, commensalism Facilitation (+/+ or 0/+) Interspecific competition: resources are in short supply Species interaction is -/- Competitive exclusion principle: Two species cannot coexist in a community if their niches are identical. The one with the slight reproductive advantage will eliminate the other Resource partitioning: differences in niches that enable similar species to coexist Ecological niche: the sum total of an organism?s use of abiotic/biotic resources in the environment

POPULATION ECOLOGY Chapter 53 Population = group of individuals of a single species living in same general area Density: # individuals / area Dispersion: pattern of spacing between individuals Introduction Determining population size and density: Count every individual Random sampling Mark-recapture method Patterns of Dispersal: Clumped ? most common; near required resource Uniform ? usually antagonistic interactions Random ? unpredictable spacing, not common in nature Additions occur through birth, and subtractions occur through death. Life table : age-specific summary of the survival pattern of a population Demography: the study of vital statistics that affect population size Survivorship Curve: represent # individuals alive at each age

AP BIOLOGY NOTES ON ECOLOGY (CHAPTERS 50 ? 55) CHAPTER 50 ? INTRODUCTION TO ECOLOGY AND THE BIOSPHERE YOU MUST KNOW: The role of abiotic factors in the formation of biomes. Features of freshwater and marine biomes Characteristics of the major terrestrial biomes NOTES: WHAT DOES ECOLOGY STUDY? Ecology ? the Study of Interactions Between Organisms and the Environment Organisms all live in complex environment that include: Abiotic components ? The nonliving components of the environment such as water, light, temperature, nutrients, soil. Biotic components ? the living components of the environment such as other organisms as foods, other resources, or predators. These environmental factors limit the geographic range (distribution) and the abundance of species.

3.2 Energy and Ecosystems I will wait until everyone is in their seats and has only a piece of paper and a pen/pencil and your homework on your desk. Again, the expectation is that there is no talking during the quiz. Talking will result in your quiz not being collected. Daily Quiz Name the ecosystem you created for homework List all 10 biotic and 5 abiotic factors Which biotic and abiotic factor did you remove? What are the consequences of it being removed? When you finish your quiz, please collect your assignments by the door. Daily Quiz Question Content Objective Students will? Follow the path energy takes in an ecosystem. Distinguish between producer, consumer, and decomposer. Model a trophic pyramid Demonstrate the first and second law of thermodynamics.

Ecology Section 3.1 Today we will? Content Objectives Use prior knowledge and group discussion to problem solve. Intro to Ecology Language objectives Take a pretest Complete a worksheet with a group Activity today: In your groups you will? Work together without using your book to answer the questions. You must discuss and come to a group consensus. Meaning: the definition must be discussed, it can?t be just what 1 person says. When you are done, come ask me what to do next. Ecology What do you think?? Tell me what you thought ecology was before you corrected. Ecology: The study of the interactions between organisms and the biotic and abiotic factors of their environment. What is abiotic? What is biotic? All the living factors of any ecosystem
