Trophic levels
This is the first trophic level and they are all autotrophs.
Producers
What percent of energy to Tertairy consumers get?
0.1% of the original energy produced by producers.
What animal eats the primary consumer in an ecosystem?
Parasites feed on a host. Are parasites examples of autotrophs or heterotrophs?
Heterotrophs.
Draw a picture of a polar bear eating a salad on vacation in Texas.
Garcia decides.
This is the fourth trophic level and 3rd consumer.
Teriary consumers.

To which way should the arrows point in a food web or food chain if it shows a bunny eats grass?

This is the second trophic level and they are all herbivores.

Draw a food chain with a bush, a grasshopper, a mouse, and a hawk.
Must have the arrows pointing the right way.
In deep sea oceans, no sunlight gets through. Some organism use chemosynthesis to make energy from chemicals in deep ocean volcanic vents. What niche doe these organisms take in that deep ocean ecosystem?
Producers.
Triple points!!!
Spin the wheel.
Stuff happens...
Where does all energy in an ecosystem come from?
The sun!
What percent of energy to producers get?
100% of energy, they produced it.
What is the difference between a food web and a food chain?

Triple points!!!
Draw a picture of a spider trying to decide between eating a fly and a grasshopper caught in it's web.
Garcia decides
¿Qué hace un pez en el mar?
Nada, Nada, Nada...
Are decomposers autotrophs or heterotrophs?
Heterotrophs. They eat dead things. Double Points!!
Draw an energy pyramid with the flow of energy.
Must have flow of energy labeled with trophic levels.
Make a food web that could exist outside here in Austin. Food web, not a food chain.
Garcia decides. Must have at least two food chains.
Double points!!
What would happen in an ecosystem if there are WAAAAAAY too many deer and not enough food for them to eat or predators to eat the deer?
