Provides us with food |
|
Regulating in herpetofauna |
amplihbians help with energy cycles |
|
Supporting in herpetofauna |
help with soil airation garter snake eating insect |
|
How amphibians contribute to healthy ecosystem |
They contribute to food web, move energy around, eat a lot of things -They are the food source for some humans, provide food for other species that humans rely on, they serve as both predator and prey. |
|
role of biodiversity to humans |
different foods we eat, -different medicines from plants and animals, -animals and plants can act as bio-idicators (warning that its something wrong) |
|
Cultural |
aestheic beauty, recreation |
|
Provisioning |
provide us with resources i.e food water |
|
Regulating |
controls important cycles and services i.e climate, water flow, energy |
|
Supporting |
basic ecosystem processes i.e soil formation, pollination |
|
Negative feedback |
System reverses a directional change -ex Algae growth in a pond, going up and down -ex the seasons making temperatures go up and down |
|
Positive Feedback |
Positive feedback: Reinforces directional change - ex: As temperature rises ice melting increases |
|
2 fundemental issues |
Quality and Access |
|
major sources of loss of freshwater |
-Glacial melt is going predominantly to the ocean (seawater; no longer freshwater) -Removing freshwater at often faster rates than are replenished |
|
challenges regarding desalinization |
Pros: there is lots of salt water, a lot of access to it Cons: very expensive to desalinate water, very slow process, get a lot of salt after its done, not energy efficient and requires freshwater to do it |
|
factors that influence how water flows |
-Follows the slope: All water (even groundwater) has slope -Gravity -Pressure -Permeability |
|
how the flow of water can influence human health |
Well water need a lot of pressure in order to draw water -permeable soil you’ll always have well water Health: Contaminants like lead in soil, or lead pipes can leach out and end up with it in water and arsenic |
|
ocal, regional, national and international complexities of water concerns and solutions |
Droughts:regional, national, or local -borders for states are rivers, -damning up rivers for hydroelectric power and water not making its ways to countries that need the water |
|
Igneous |
made from solidified mantle ex: basalt, granite |
|
Sedimentary |
made from sediments such as sand or silt are chemically cemented into rock ex: sandstone |
|
Metamorphic |
made from heat and pressure -ex: marble |
|
Rock Cycle |
Erosion weathering transported deposition -Sedimentary -metamorphic -igneous |
|
natural and unnatural minerals of human health concern |
-working in mine inhaling coal dust -lead paint lead pipes, -lead getting in water -“Assessment of human exposure to hazards in the environment is often the weakest link in most human health risk assessments.” |
|
effects on the body of having too much, or too little of micronutrients/metals |
Body can become deficient, get poisoned, and result in death |
|
4 Components of Nitrogen Cycle |
Nitrogen Fixation Nitrification Ammonification Denitrification |
|
Nitrogen Fixation |
goes from nitrogen gas to amonia, from baterica and lightening N2-->NH3 |
|
Nitrification: |
In soil and water: transformation to allow it to cycle through the biosphere -• Ammonia (NH3) dissolves in water to form ammonium (NH4) -• Bacteria then convert the ammonium (NH4) to nitrite (NO2) and nitrate (NO3) |
|
Ammonification: |
When decomposers break down waste/dead plants and animals, ammonia (NH3) is released back into the soil (ammonification). |
|
Denitrification |
Nitrogen back to the atmosphere, gets transformed |
|
Carbon cycle interaction with rock cycle |
Carbon that is released from shells of animals, and used in sedimentary rock |
|
ways humans have a major impact the carbon cycle |
The excessive emission of carbon into the atmosphere from burning of fossil fuels and deforestation |
|
ways humans impact nitrogen cycle |
before fertilizer: Farmers would harvest the crop and leave left over plant stuff to break down so nitrogen will go back in soil i.e.-spreading manure: -crop rotation |
|
ways humans impact nitrogen cycle (now) |
Today they have chemical fetilizers that put nitrogen in soil -Burning fossil fuels creates nitrioxide, creating acid rain |
|
ways that the nitrogen cycle impacts (and is affected by) the water cycle, |
Nitrogen washing off into our waterways and affecting water cycles, nitrogen washing off and killing fish |
|
how we can measure current and historical climate changes |
Using ice cores from the arctic, you can drill out the ice core from millions years ago and extract the bubbles in the ice. You can see a lot of CO2 in the bubbles, which indicates the temp at the time |
|
greenhouse gases |
H2O(water) CO2 (Carbon) CH4 (methane) N2O (nitrogen Oxide) |
|
CO2 is much higher than it has ever been in history due to the increase of burning of fossil fuels and deforestation, since the industrial revolution there has been an influx of CO2 in the atmosphere |
. |
|
ways that humans impact greenhouse gas emissions. |
Burning fossil fuels, deforestation, agricultural |
|
major evidence we have for climate change |
melted ice caps, melted glaciers, rise of sea levels, bubbles in the ice cores, major shifts in weather |
|
9 major consequences of climate change |
1. Global temperature rise 2. Warming oceans 3. Shrinking ice sheets 4. Declining arctic sea ice 5. Loss of permafrost (methane burps?) |
|
9 major consequences of climate change continued |
6. Glacial retreat 7. Sea levels rise 8. Extreme events 9. Ocean acidification |
|
impact climate change can have on non-human species and how these changes can impact human health |
Because the planet is warming, summer cycles are becoming warmer, mosqitos emerging earlier---rise in malaria trees are moving northward areas that were forrested becoming more like deserts |
|
relationship between fossil fuels and the carbon cycle |
Fossil fuels impact the carbon cycle because the influx of fossil fuels causing an influx in carbon in the atmosphere, altering the carbon cycle |
|
ethical concerns of climate change |
areas hit hardest by climate change tend to be developing impoverished countries |
|
non-renewable |
coal oil gas and nuclear |
|
Renewable |
Solar, wind, Biofuel |
|
Food Web |
Teracary(humans, lions) secondary consumers(eat primary consumers) Primary consumers(animals that eat plants) Primary producers(plants) Decomposers (worms) |
