HOMEWORK:

Pop & Eco Investigations 3 & 4 Quizlet





Modified homework for those who are qualified:



By completing this unit, students will…

Know
Aquatic, terrestrial, detritus, consumer, producer, decomposer, food chain, food web, photosynthesis

Understand

  • An ecosystem is a web of interactions and relationships among the organisms and abiotic factors in an area.
  • Scale models of ecosystem can be used to make generalizations about larger ecosystems.


Be able to….
  • Assemble abiotic elements of aquatic and terrestrial mini ecosystems.
  • Introduce organisms into aquatic and terrestrial mini ecosystems.
  • Use a scientific log to record interactions and changes in mini ecosystems over time.
  • Describe how organisms depend on abiotic elements in their ecosystem.

LESSON 1

EQ: How can we determine the abiotic needs of organisms in an ecosystem?

Mini- Ecosystem Observations


You will be making regular quantitative and qualitative observations of your mini-ecosystems to determine their abiotic and biotic properties.
  1. Carefully study the pictures of the probes below.
  2. View the video --> Video on how to use the probe.
  3. You may ONLY put the metal portion in the the probes in the soil or water. The instrument panel MUST NOT GET WET!
  4. Wipe all probes dry before returning them.

Populations and Ecosystems
Investigation 4 Mono Lake & Food Webs

By completing this unit, students will…


Terms:
Food web, food chain, producers, consumers (primary, secondary, tertiary), decomposers, trophic levels, Photosynthesis, energy, biomass, herbivore, carnivore, omnivore, detritus

It’s important to understand that…

  • The dynamics of a simple ecosystem such as the alkaline lake ecosystem of Mono Lake.
  • A food chain is a sequence of organisms that eat one another.
  • All the feeding relationships in an ecosystem is called a food web.

Students will be able to….
  • Research the functional roles of the 12 organisms in the Mono Lake ecosystem.
  • Diagram a food web using arrow to show what eats what.
  • Explain the functional roles and feeding relationships that constitutes a food web.

LESSON 1

EQ: What are the biotic and abiotic factors that influence the Mono Lake Ecosystem?

FOSS Text: Pages 19-21

Food Chains, Webs, & Decomposers

Cool Food Web Game

Build a food web

Energy flow in an ecosystem

Autotrophs and Heterotrophs

LESSON 3

EQ: What are the feeding relationships of the 12 organisms in Mono Lake ?

Lab Book: Page - Not Applicable
FOSS Text: Pages - Not Applicable

You will use 12 cards of Mono-lake organisms along with cut out arrows to show the feeding relationships of the organisms of mono lake. The arrows will show where the energy is being transferred to.
