Energy Flow in Ecosystems
AKA Bean Lab Day 1Slide2
Observe the DATA from the 2 ecosystems and look for similar patterns between the sets.
Quietly
discuss as a group (do NOT give any info to other groups or yell out answers in the class)
*****
List patterns in you notebookSlide3
Similar Patterns
1.As you go down the pyramid there are more organisms.
2. Smaller species are eaten by larger species.
3. Carnivores are always at the top.
4. Both are food chains and both start off with grass.5. Organisms at bottom are plants.6. Dominant consumer is a predator.7. Organisms have camouflage.8. Top predators have smallest population.
Now that we have the patters, in your notebook
write 1-2 questions about the patterns we saw.Slide4
Similar Patterns
1.Both show food chains (circle of life).
2. Both start off with plants.
3. Always a top predator.
4. Some animals eat the plants.5. Arrows always go up.6. Creatures eat plants, other creatures eat creatures. 7. Predators have smallest population.8. Graph shows the food chain.
Now that we have the patterns, in your notebook
write 1-2 questions about the patterns we saw.Slide5
Similar Patterns
They all go from prey to predator.
They both have top predators.
They both have plants at the bottom.
Plants have a bigger population.Animals eat each other.Predators have a smaller population.
Now that we have the patters, in your notebook
write 1-2 questions about the patterns we saw.Slide6
Similar Patterns
Starts with grasses/plant life.
They all contain predators at the end.
Similar structure in different habitats.
Goes in ascending order (smallest animal to biggest).Both contain biomass (grasses have the biggest).
Now that we have the patters, in your notebook
write 1-2 questions about the patterns we saw.Slide7
Similar Patterns
Grass is at the bottom.
Both show food chains.
Grass is most of the biomass.
Grass eating animals are eaten by carnivores.Top of food chain is predator, bottom is a plant.Predator has smallest biomass.
Now that we have the
patterns
, in your notebook
write 1-2 questions about the patterns we saw.Slide8
Similar Patterns
Predators (at the top) and Prey (at bottom).
Starts with plants and ends with a top predator.
Bigger populations of prey/plants.
Contains producers and consumers.Initial food is transferred to predator.
Now that we have the patterns, in your notebook
write 1-2 questions about the patterns we saw.Slide9
Questions about patterns
Is it like this in every ecosystem?
Why do these patterns exist?
What happens if an animal is missing?Why do they both start with plants/grass?
Why are the top predators the smallest in population?Is there always a dominant predator in the food chain?Section C: Write a Driving ? That would answer most of these ?s.Slide10
Questions about patterns
Why do the arrows always go up?
Why are there more plants than wolves?
What would happen if there were no plants?Why do some eat plants and others eat other animals?
Why are predators the smallest amount?Why does it start off with plants?Does this exist everywhere else?Why does the pyramid go from a deer to a wolf?Section C: Write a Driving ? That would answer most of these ?s.Slide11
Questions about patterns
Why are these patterns like this?
Why does it start with plants/grass?
Why are there less predators?Why can’t smaller animals eat the bigger ones?
What happens if there is too many of one?How long does the cycle last?Section C: Write a Driving ? That would answer most of these ?s.Slide12
Questions about patterns
What is biomass?
Why is there a small amount of predators?
Why do they contain biomass?Why does the grass have a bigger biomass?
Why do the arrows point up?Why is one food chain more complex?Why is there different plant life?Does anything eat the wolf/predator?Section C: Write a Driving ? That would answer most of these ?s.Slide13
Questions about patterns
What is biomass?
Why do predators have less biomass?
Why is most of the biomass grass?Why do food chains work this way?
Why are plants always at the bottom?Section C: Write a Driving ? That would answer most of these ?s.Slide14
Questions about patterns
Why does the initial food source get transferred?
How effective is the energy transfer ©Evan
What other kinds of food chains are there?Why don’t the animals at the top eat the plants?
Why is the initial food source grass?How would the predators be effected if there was less food?Section C: Write a Driving ? That would answer most of these ?s.Slide15
Driving Questions
Why are there more organisms at the bottom of the food chain?Slide16
Driving Questions
Why are there more plants than wolves and why do the arrows go up?Slide17
Driving Questions
Why are there less predators and what happens if there is too many?Slide18
Driving Questions
Why does the biomass decrease as you go
up? Slide19
Driving Questions
Why does biomass
decrease as you go up the food chain?Slide20
Driving Questions
Why does the initial food source get transferred and how effective is this transfer?Slide21
