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
