Drill Cats in borneo activity on desks TURN

Drill: � Cats in borneo activity on desks � TURN IN OCEAN ACIDIFICATION LAB � TURN IN MEDIA MATTERS IF YOU HAVE NOT ALREADY

Objective �Students will review ecological vocabulary in order to gain a deeper understanding of the inner workings of ecosystems.

Agenda � Read over Food-Web Activity (highlight key vocab) � Food-web card game � Lab questions � Ecosystem services � HW: Make sure notes are complete for Tuesday � Next Quiz: Chapter 3 and 4 – October 7 th (B-day) &10 th (A-day) � UNIT TEST: October 14 th (B-day) & 17 th (A-day)

Drill: � Would you estimate that most of your daily caloric intake comes from a high trophic level or from a low trophic level? Explain your answer. � HAVE NOTES OUT TO CHECK � TURN IN MEDIA MATTERS IF YOU HAVE NOT ALREADY

Objective � Students will be able to complete a lab in order to distinguish the amount of energy that is required to support their own diet.

Agenda � Re-do/Re-take Info � Eating at a lower trophic level activity � Next Quiz: Chapter 3 and 4 – October 7 th (Bday) &10 th (A-day) � UNIT TEST: October 14 th (B-day) & 17 th (Aday)

Re-do/Re-take Dates � For APES, I will be available at these times: ◦ Tuesday morning: 7: 15 -7: 45 (3103) ◦ Thursday morning: 7: 15 -7: 45 (3103) ◦ Tuesday after school: 2: 15 -2: 45 (3105) ◦ Lunches – any day, any lunch (3105) � Going forward, you must let me know ahead of time what day, and time you will be coming.

Trophic Pyramid

�What are trophic levels? �What is the rule of 10%? �How are these related?

Drill: � What is the difference between net primary productivity and gross primary productivity? � Use your notes, or your activity from last class to help you answer.

Agenda � Quiz � Quick Notes of Productivity � Part 2 of NPP Lab � Explanation of Formal Lab Report for NPP Lab � Begin evolution � HW: Read/Notes Chapter 5 � Study for Unit Test (10/17/16) � DATE CHANGE: Next Media Matters Due Nov. 1 st

Types of Productivity: � 1. Gross Primary Productivity (GPP) � 2. Net Primary Productivity (NPP) � 3. Net Ecosystem Production (NEP)

Gross Primary Productivity (GPP) Rate of photosynthesis among ecosystem’s producers Gross primary productivity (GPP) is a measure of the total amount of chemical energy (glucose) created from the sunlight an area receives.

Net Primary Productivity (NPP) What is left over for the consumers to use after the producers use some of the total biomass for respiration � �Measured in units of energy of biomass available to consumers in an area over a given time �NPP = GPP – Respiration of Plants

The Earth is Only 2% Efficient � This is only approximately 1% the radiation received from the sun! � What happens to the other 99% of energy?

Albedo � The ability of some areas of the earth to reflect solar radiation back out of the atmosphere

Why Care About Productivity? � Productivity can help us measure: 1. Ecosystem services and biosphere production AND 2. Human impact on the biosphere

Factors Affecting NPP High NPP Low TEMPERATURE High NPP Low NUTRIENTS High Low High Precipitation

Our Grass Seed � Known NPP for Fescue Grass Seed is 58 g/cm 2/year � We will compare what you all measured over 10 days.

� PROBLEM: Identify the Net Primary Productivity of an environment specifically grass. � HYPOTHESIS: If fescue seeds are planted and grow for 10 days, then the NPP of the grass will be lower than the known NPP of fescue plants, . 0058 g/m 2/year, because of the limited amount of energy that a window light can input into the system as compared to natural sunlight.
