Photosynthesis
What living thing goes through photosynthesis to survive?
Plants or producers
Give an example of a renewable resource
water, air, soil, wind, plants, animals
remains of once living things buried deep in the ground
What is an example of a producer?
plant
What is weathering?
the breaking down of rocks
What are the two things that a plant produces during photosynthesis?
sugar/glucose and oxygen
Give two examples of non-renewable resources
oil, coal, fossil fuels, natural gas
Give an example of a fossil
a dinosaur bone, etc.
What is the main source of energy for a food chain?
sun
What is erosion?
the moving of rocks
What three things does a plant need to go through photosynthesis?
water, sunlight/light energy, and carbon dioxide
What is a problem with using up all of the non-renewable resources?
they take longer than a lifetime to replace; once they're gone, they're gone
How can fossils help scientists?
they give information about how animals and environments changed over time
What is the difference between a food chain and a food web?
a food web is made up of a bunch of food chains
Give an example of a landform that had deposition
delta or volcanic eruption
Why would a plant put in a closet not grow as well as a plant in the sun?
a plant needs sunlight to go through photosynthesis
Why is water considered a renewable rather than non-renewable resource?
If paleontologists find a fossil of a shark in a mountain, what does that mean?
There used to be an ocean there.
What do the arrows mean in a food chain/food web?
The direction the energy is moving
How are canyons formed?
weathering by water
6Co2 + 6H2O + light energy = C6H12O6 + 6O2
What does this formula represent?
photosynthesis
Fossil fuels are classified as a non-renewable resources because....
they take hundreds of years to replace
fish, alligator, turtle etc.
grass -> grasshopper -> mushroom -> snake -> alligator
Correct this food chain.
grass -> grasshopper -> snake -> alligator -> mushroom
What does WED stand for and explain.
Weathering- breaks rocks down
Erosion- moves the rocks away
Deposition- drops the rocks in a new place
