A field biologist identifying the total number of different species in a given area within an ecosystem is measuring ______________.
True or False: Invasive species are any non-native species that are introduced to an ecosystem in a geographic location far from their native ecosystem.
A species, often introduced by humans, that takes hold outside its native range.
how does biodiversity enhance ecosystem services? identify 2 of the 4 types and provide a specific example of how biodiversity improves each of them
provisioning: water, shelter, food
-improved types of food, shelter, ecological niche for all organisms and humans have a variety of choices
regulating: water cycle, climate
-improved by keeping water clean and the earth temperature stable, humans are healthier
A system formed by the interaction and exchange of energy and matter by a community of organisms, abiotic and biotic
explain why "buying less stuff" is an action individuals can take to reduce environmental degradation using the IPAT equation
IPAT is impact=population + affluence + technology
buying less affects technology because it reduces the number of things an individual consumes
buying less also reduces the affluence which means individuals own less stuff so the impact is reduced
2 reasons why uncertainty is important to the scientific process
accounts for ignorance and complexity
scientists question and further revise hypotheses and research and they must use correct protocol in experiments for peer review
Concentrated solar heat technology would most likely be applied in what framework
Generation of distributed power (analogous to power plant)
Which of the following energy resources is most utilized by humans currently?
What kind of energy is biomass?
Within a power plant, the primary fuel is typically burned in a boiler to heat water and then create steam followed by which process?
Humans are living organisms and thus need a continuous supply of energy to sustain ourselves. What type of energy do we consume to meet this need?
Mountain-top removal, the clearing and blasting away of the entire top of a mountain, is associated with extraction of which non-renewable energy resource?
what would affect the amount of energy trapped as heat in the Troposphere that determines the temperatures on Earth?
Changes in the amount of sunlight the Earth receives due to fluctuations in amount of radiation the sun is emitting
Changes in the color of the surface of the Earth that affect how much incoming sunlight is absorbed
Changes in populations of microalgae that would influence the overall rate of photosynthesis in oceans
Changes in the concentration of greenhouse gases in the atmosphere
2 examples of human health impacts of climate change
worsened asthma and allergies from increased pollution from burning fossil fuels
heatstrokes and water-borne diseases from contaminated water from run-off
Humans impact the phosphorus biogeochemical cycle via which activities?
Mining of phosphorus to produce fertilizers which are then applied to agricultural fields
Water is cycled into the atmosphere by _____________________.
evaporation from surface water and soils
transpiration in plants
14. The increase in concentration of a toxic compound, such as a pesticide, found in the tissue of plants and animals as you move up trophic levels is a process known as ______________.
build up over time in the body
accumulation of pollutants at successive levels of the food chain
Humans impact the nitrogen biogeochemical cycle via which activities?
-Accelerating nitrogen fixation through the Haber-Bosch process to manufacture
-Using fossil fuels in cars and power plants that release reactive nitrogen into the
-Planting crops that enhance nitrogen fixation in the soil in large scale agricultural
Why are biological pest control practices better than chemical pest control practices?
Less harmful materials enter the environment
Biological pest control methods require an understanding of ecology by those who
employ them while chemical methods do not
true or false: Globally most water is used for agricultural purposes
2 pros and 2 cons of monoculture systems typically utilized in agriculture
pros: 1. easy to grow only one crop-all resources and energy spent on one
2. crop can be perfected/ideal-all resources spent on it
cons: 1. lack of genetic diversity-cannot adapt resistance to pests
2. lack of species richness-not all the nutrients used, loss of water/nutrients
why processed foods tend to have higher carbon and water footprints than unprocessed foods
more energy and water goes into making processed foods in the transportation and packaging and distribution because they aren't made naturally.
integrated pest management
the use of both biological and chemical methods to control pests safely and economically
integrated pest management example
repairs, traps, bait, poison
