Eco Mastery Qs Flashcards
What does the ecological footprint measure?
- How much earth it takes to give you resources
- How much earth it takes to absorb your waste
Using renewable resources sustainably
Use renewable resources slower than they can replace themselves
Limiting factors (for Growth of population)
Temperature
Light
Water and food
pH
Explain how adaptions help organisms in specific ecosystems
Mountain
Pine tree: Waxy Coating (Waxy coating on pine needles prevents moisture loss in dry air)
Mountain Goat: Strong Muscles (help the climb and dig through snow)
Urban Forest
(Densely wooded area)
Vines: Twinging Stems (Help it wrap their stems around other organisms to get more sunlight)
Barn Owl: Silent flight (Soft body feathers that muffle sound which allows them to surprise their prey)
Explain what happens to the 90%
1- While the snake is watching the frog-the frog is using energy to hop away (energy that the snake will not be able to use)
2- Not al frogs get eaten by the snake
3-When the snake does catch that frog, it will not be able to fully digest it (and use all the energy)
Describe 3 specific movements of carbon through its matter cycle
o - Lithosphere to Atmosphere ( carbon is released through decomposition of dead organic matter in the soil and through the metabolic processes of soil microbes
o -Atmosphere to Hydrosphere (Carbon is absorbed by the ocean and other bodies of water)
o -Hydrosphere to Biosphere (Carbon is absorbed by marine plants during photosynthesis
Lake
A large body of water surrounded by land
Turtle: Shell (protects them from predators)
Lily Pads: Floating Leaves (Maximize sunlight for photosynthesis)
River
Torpedo shape
Helps them move against current
Strong roots
Plants have strong roots to keep them in place and bending stems
Why can’t a population increase in size forever?
Limited resources
Describe two advantages and two disadvantages of GMOs
Advantage
Make more food (bigger fruit from a tree)
Can make them resistant to drought and disease
Disadvantage
Companies own GMOs which can leave to legal issues
Genetically identical, if one of them gets sick then they all get sick
Explain how greenhouse gases warm the earth
Sun’s energy hits earth’s atmosphere and some of it is converted to heat. The heat tries to leave the atmosphere but the greenhouse gases trap it
Explain three possible effects of global warming
melting ice cause sea levels to rise
Changing climate
Change in distribution of food and water
Explain three harmful effects of deforestation
Lost of habitat
Trees aren’t there to absorb water so there is more Flooding which causes more Erosion
Without trees, less photosynthesis, more co2 is left in the air
Why is there no waste in natural ecosystems?
B/c the waste of one organism is a resource for another
Describe the three main requirements of a sustainable energy policy
Increase energy efficiency
Clean up emissions from fossil fuels
Use alternative energy sources when applicable
Describe how energy can be used more efficiently
We can use more energy efficient appliances which give you the same amount of work for less energy
Energy efficient light bulbs
Get same amount of light for less energy
Insulation
Have the same temperature stay for longer for the same amount of energy
Carpooling
Move more people for the same amount of energy
Cave
Lake
