1. Entry Task: Lab Notebook 10/13/14
In at least 4 sentences, describe when a human can occupy more than one trophic level and why.

2. Carrying Capacity
Learning Target: I can explain how carrying capacity of the Great Salt Lake will be affected.

3. Great Salt Lake Trophic Pyramid
Let’s go over the GSL trophic pyramid.
Northern Harrier
Avocet
Eared Grebe
Brine Shrimp
Brine Fly
Halobacteria
Cyanobacteria
Diatoms

4. Biodiversity of the Lake
Cyanobacteria is a bacteria. It doesn’t eat because it makes it’s own energy from the sun.
Diatoms are algae. They also make their own energy from the sun.
Halobacteria are Archaea. They also make their own energy from the sun.

5. Biodiversity of the Lake
Many organisms live in or near the lake.
Northern Harrier is a bird.
It eats the Avocet, another bird.
Avocets eat Brine shrimp and Brine fly.
Eared Grebe also eats Brine fly.
Brine fly eats Cyanobacteria and Diatoms.
Brine shrimp also eats Cyanobacteria, Diatoms and it’s the only one that eats Halobacteria.
