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.

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.

UNIT 15 - ECOLOGY List of Terms Ecology: study of interactions of organisms with their environment and with each other Population: group of individuals of one species in one area that can breed and interact with one another Community: all the organisms in one area Ecosystem: All the organisms in an area and abiotic factors in that area Abiotic factors: nonliving, include temperature, water, sunlight, wind, rocks, etc. Biosphere: global ecosystem Biotic potential: max rate at which a population can increase under ideal conditions Influenced by factors like age at which reproduction begins, lifespan during which you can reproduce, # of reproductive periods in lifetime, and the max # of offspring the organism can produce

Chapter 54 Ecosystems Lecture Outline Overview: Ecosystems, Energy, and Matter An ecosystem consists of all the organisms living in a community as well as all the abiotic factors with which they interact. The dynamics of an ecosystem involve two processes that cannot be fully described by population or community processes and phenomena: energy flow and chemical cycling. Energy enters most ecosystems in the form of sunlight. It is converted to chemical energy by autotrophs, passed to heterotrophs in the organic compounds of food, and dissipated as heat. Chemical elements are cycled among abiotic and biotic components of the ecosystem. Energy, unlike matter, cannot be recycled.
