• Explain the difference in the two lakes / ponds
Do Now part I
• Reading of 108 – 118 stopping at Ecosystems Interact. • Hypoxia, Positive & negative Feedback loops &
homeostasis. How does Eutrophication occur specifically in the Gulf of Mexico. Mr. Walsh will cover
• All others to be announced shortly• Explain Lithosphere, Atmosphere, Hydrosphere &
Biosphere. Abiotic vs. Biotic.• Energy Flows (diagram 115)• Energy is converted to Biomass• Impact of Phosphorous & Nitrogen in water systems.
Boards - modified
• Explain Lithosphere, Atmosphere, Hydrosphere & Biosphere. Abiotic vs. Biotic. Group 1
• Energy Flows (diagram 115) – Group 2• Energy is converted to Biomass – Group 3• Impact of Phosphorous & Nitrogen in water
systems. Group 4• Ecological Services – Group 5 (explain the
slide)

• As tables work on the following pages: 108 – 118 stopping at Ecosystems Interact. Read and then discuss as a table
• Hypoxia, Positive & negative Feedback loops & homeostasis. How does Eutrophication occur specifically in the Gulf of Mexico.
• Explain Lithosphere, Atmosphere, Hydrosphere & Biosphere. Abiotic vs. Biotic.
• Energy Flows (diagram 115)• Energy is converted to Biomass• Impact of Phosphorous & Nitrogen in water systems.

• Explain this graph with only the use of your notebook.

Net primary productivity of ecosystems
Productivity = rate at which ecosystems generate biomass. High net primary productivity = ecosystems whose plants rapidly convert solar energy to biomass
Chapter 5 – finish the chapter for class (Today)For today’s class, be ready to explain the following (hint put this into your notebooks (or where ever you keep your notes)Also, Vocab Quiz Monday. Unit 2 test on Wednesday not Monday! Monday will be a quick review. Hydrological Cycle – All aspectsCarbon Cycle and how we are negatively impacting it. Nitrogen Cycle and the impact on the oceans. Also, what is nitrogen fixing & the Haber-Bosch ProcessPhosphorus Cycle – impact on fresh water ways
Homework Part II
Hydrological Cycle – All aspects
Boards
Carbon Cycle and how we are negatively impacting it.
Boards
Nitrogen Cycle and the impact on the oceans. Also, what is nitrogen fixing & the Haber-Bosch Process
Boards
Nitrogen Cycle and the impact on the oceans. Also, what is nitrogen fixing & the Haber-Bosch ProcessIncase it is not explained well:
• Haber-Bosch process = production of fertilizers by combining nitrogen and hydrogen to synthesize ammonia. Prior to this, to achieve the same effect farmers had to dump a lot of fertilizer to some of the nitrogen to activate within the soil. – Humans overcame the limits on crop productivity
Boards
Phosphorus Cycle – impact on fresh water ways
Boards
• Landscape ecology = studies how landscape structure affects the abundance, distribution, and interaction of organisms
• Patches = form the landscape
