Energy Flow & Ecological Hierarchy

This week will be dedicated to discussing the interactions that exist among communities within an ecosystem. The emphasis for this week is “interaction”.

BY THE END OF THIS WEEK, you should be able to:

  • define all terms from the previous weeks,

  • differentiate all terrestrial and aquatic biomes from last week,

  • discuss how energy flows from a primary producer to consumers through a food web,

  • describe the differences between terms that describe how organisms get their nutrients (e.g. carnivore, frugivore, saprophyte,)

  • differentiate the five types of symbiotic interactions,

  • discuss trophic cascades while describing keystone species, and

  • list the levels of ecological hierarchy up to ecozones then list the 8 different ecozones.

Week 23 - Biology

Your Week Ahead

Day 1: Finishing Biomes

  1. You’ll use the day to finish your review of terrestrial and aquatic biomes.

  2. AFTER CLASS, study for your test this Thursday/Friday! It’s covering Meiosis, Genetics and Inheritance, DNA Structure, DNA Replication, and Central Dogma. This is videos 2-8 in the genetics section of the content videos page.

  3. Note - No journal this week. As a bonus for you checking the website, if you write the names of two ecozones correctly next to your name on the test this week, you’ll get a bonus point. Don’t talk to others or mention this in class - it’s just to see who’s regularly checking the website.

Day 2: Trophic Cascades & Test Prep

  1. We will begin class with a quick review of key points to see if you’re prepared for your test.

  2. After that, we’ll continue with a discussion on trophic cascades and if we have time, dive into the coevolutionary relationships among animals in the Brazilian Cerrado.

  3. AFTER CLASS, study!

Day 3: Genetics Test

  1. You’ve got this! Today will be all dedicated towards your test. Any extra time can go towards finishing your terrestrial and aquatic biomes packet if you haven’t already done so.

IMPORTANT DATES

Test this Thursday/Friday! See Day 1 discussion for content review

Did you…?

  • … finish your terrestrial & Aquatic Biomes content from last week?

  • … review your terms to know? We have a lot of new terms that we aren’t directly addressing in class.

  • … Finish your 23.1-23.2 discussion on energy flow and ecological hierarchy?
