What is biodiversity
The number of different kinds of organisms in an area
How much of earth's water is fresh water?
3%
What two gases make up the bulk of our atmosphere and how much?
Oxygen ~ 21%
Nitrogen ~ 78%
Biome with some grasses, very cold, has permafrost, and little precipitation
Tundra
Resources that can not "grow back" after they have been used
non renewable resource
What is the number one leading threat to biodiversity?
Habitat Loss
Of earths water, only about 1% is available as fresh drinking water, where is the rest of the fresh water?
Frozen as polar ice
Name the layers of the atmosphere in order
troposphere, stratosphere, mesosphere, thermosphere
Biome where a majority of the trees lose their leaves.
Temperate deciduous forest
How are energy sources such as coal or natural gas used to generate electricity?
They are burned to produce steam which turns a turbine to produce power.
What 3 things give invasive species the ability to avoid carrying capacity?
- No disease
- No competition
- Large amounts of resources
What is the difference between an aquifer and a watershed?
An aquifer is a collection of groundwater while a watershed is a collection of surface water
Which gas is leading the global warming trend?
CO2
This biomes covers more of the earth than any of the others
Boreal forests (taiga)
Which element fuels most nuclear reactors? Is this a renewable or non renewable resource?
Uranium / non renewable
Name 3 types of symbiosis (how animals interact with each other) and a description of the relationship.
- Mutualism
- Commensalism
- Parasitism
- Predation
Apex predators due to the fact that inorganic metals accumulate almost 10 times more as they move up trophic levels due to amount of contaminated food eaten.
Name 2 minor layers and their characteristics
-ozonosphere
-magnetosphere
-ionosphere
-exosphere
Two factors that determine type of biome
Climate + Precipitation
name one benefit and one drawback to using renewable energy.
Renewable sources are unlikely to be used up, cheap to generate, pollute less, and create domestic jobs, but are expensive to build infrastructure, produce less energy, and have some limited availability.
fill in the blanks and describe dietary habit
producer, primary consumer, secondary consumer, apex predator
Describe the step by step process of Eutrophication.
1. pollution 2. runoff 3. algae bloom 4. algae competition and death 5. accumulation of decaying material 6. Hypoxia and death
explain temperature trend through the atmospheric layers and why it either warms or cools.
tropo - warm to cold
strato - cold to warm
Meso - warm to cold
thermo - cold to extremely hot
What is the difference between weather and climate
Climate is a timely average while weather is the immediate temperature and precipitation impact.
What is the biggest concern with nuclear power and what event contributed to these concerns?
Nuclear reactor melt down / Chernobyl
