UNIT 2 Homework Sheet: & LEARNING GOALS FOR THIS UNIT: TEST on ????????? (100 pts) By the end of this unit you should be able to: 1) Describe the “energy economy” of the environment, including the concept of . 2) Perform dimensional analysis calculations, especially involving units of Energy 3) Apply biological knowledge of natural selection, adaptation, evolution, and species interactions to . 4) Understand “niche” as the defining characteristic of a species within an . 5) Understand the different ways in which populations grow and how this is related to the reproductive characteristics & life strategies of the organisms that make up any population.

HOMEWORK SCHEDULE:  Review/Skim (no active reading necessary) sections 3-1 thru/ 3-3; Take notes (as needed) while reviewing food webs, ecosystem pyramids, and through ecosystems. These sections should be a review of your biology class.  Read sections 3-4 & 3-5 and complete active reading. Focus on understanding GPP, NPP, NEP, as well as controls over productivity, as well as ways to calculate/quantify productivity.  Read sections 4-6 through 5-2 and complete active reading. Work to understand types of species (keystone, indicator), symbioses (, , and ), competition and the competitive exclusion principle.  Read the Ecosystems chapter in the Barron’s book (pages 147-173). Focus on population characteristics, types of population growth (J- & S- Curves), r- and K-selection populations, predator-prey dynamics, and survivorship curves as well as r-values and population doubling times (the rule of 70).  Complete the AP Exam questions in the Barron’s book (pages 176-179) and then self-assess using the answers found on pages 180-183. Utilize this exercise to understand the strategies they used to answer the Free-Response Questions (FRQ’s).  Read Chapter 2 and complete active reading. Focus on energy types (kinetic vs potential); sources of energy; energy units (calorie, joule, watt, etc.); the 1st & 2nd Laws of , as well as energy conversions.  Complete the AP Questions on pages 53A & 53B, and submit them by Monday 25 Feb.  Read the Productivity Lab (on my web page) and complete pre-lab assignment OTHER WEEKLY ASSIGNMENTS w/ DUE DATES: Weekly Assignment #1: DUE Monday 24 February Construct a Food Web that has at least 15 organisms; then construct a Trophic Pyramid for that food web. Identify (1) the top predator(s); (2) any Keystone Species & (3) label each organism as K-selected or r-selected. If the producers in your food web were able to create 1000,000 lbs of biomass, then what is the estimated maximum # of pounds of top predators that your ecosystem can sustain? Explain how you came up with this number and what kind of margin of error you would put on it. Finally, in a succinct paragraph, discuss one abiotic factor that could significantly influence your food web & ecosystem.(35 points) Dr. Snyder / APES @ LCHS

Weekly Assignment #2: DUE Tuesday 25 February Carefully read over your Unit 2 review sheet. Bring to class 3 multiple choice questions that you would write for this unit. You’ll have a chance to stump your classmates…(9 Points)

Weekly Assignment #3: DUE Wed 26 February Construct an ecosystem that minimizes energy loss. How could organisms increase the efficiency of all energy transferred through an artificial ecosystem. Use your imagination, but limit your output to 2 pages (4 sides) including all figures, charts, diagrams, refs, etc… EVERYTHING!! There is no correct answer… this is a thinking exercise whereby you demonstrate your grasp on energy efficiency particularly with respect to biological systems.
