Biology (GEN) 513
Unit 9 - Ecology
TIME FRAME: 1 week
MAP LEVEL: 1
-- Students will explain that the distribution and abundance of organisms and populations in ecosystems are ultimately governed by the availability of matter and energy and the ability of the ecosystem to recycle organic materials
-- Students will describe the movement of matter and energy through different levels of organizations of living systems and show how matter and energy are transformed and conserved
-- Students will explain ways in which humans can minimize their impact on biomes
-- Students will explain the differences between the Earth's major biomes in terms of both climate and organisms.
What is an ecosystem and what are its components?
Relate the pyramid configuration to energy flow and biomass flow?
What is the distinction between a food chain and a food web and why is the food web the component of a sustainable ecosystem?
1. The role of autotrophs and heterotrophs (herbivores, carnivores, omnivores, decomposers) in an ecosystem
2. Food chains/webs and pyramids to demonstrate the flow of energy through an ecosystem
3. Define population and species
4. Growth rate: growth without limits, growth with limits, boom and bust, and zero population growth
5. Population density: density-dependent limiting factors (competition, predation, parasitism, stress) vs. density-independent limiting factors (weather, human activities)
6. Human population growth
Students in Biology will develop the abilty to:
1. Analyze a food chain/web and pyramid, including the relationships of the autotrophs and heterotrophs and flow of energy,
2. Compare and contrast the relationships between different populations in an ecosystem,
3. Determine the density-dependent and/or density-independent factor affecting a population,
4. Describe the history of human population and discuss what may happen to the human population in the future.
1. Produce a food chain/web and food pyramid
2. Analyze a food pyramid
