Technology
Application of scientific knowledge for any invention. It can be advanced machines and simple machines like glasses and pencils.
Benefits and Risks
They are favorable/good effects for the solution
Risks are bad effects for the solution.
How has technology influenced our society?
It has influenced our society by making our lives easier and made changes on our space.
What is the Engineering process?
It is a method used to make a new technology or improving it. Some steps may be repetitive and some aren’t.
Scientific method
It is used to ask questions, make predictions, and to form a experiment.
GPS
Global Positioning System
Criteria
Setting a standard on a solution. It is like the wants in the invention.
Contraints
The limit on the design
Tradeoff
When they take out one thing and switch it up for another.
What can the GPS data be used by?
It can be used by stakeholder/land developers, local governments, and conservation groups.
Why is testing important?
It is important because it gives you feedback on the design.
Habitats
includes biotic and abiotic factors, where the organism/living things live.
Ecological Niche
Environment that has everything for the organism to survive and reproduce.
Predation
When a organism eats another organism.
Biodiversity
The amount of different species in the environment.
Biodiversity Hotspot
They contain unique species in the environment.
3 symbiosis relationships between different organisms
Mutation-both benefit
Commenalism-only one benefits
Parasitism-one benefit other is harmed
Keystone
They are the species that have the top effect in the entire ecosystem.
Abiotic conditions
The range of air, temperature, and the amount of water the species can tolerate.
Factors that effect the biodiversity
Human activities
Introduction to new plants
Species being removed
Population Density
How many individuals living in a given space
Density
How much matter in given space
Formula to determine if population changed over time
Population #of individuals
————————=————————————————————————
Density Area (unit square)
Population Dispersion
This refers to how organisms seperate themselves with a population
3 main patterns
Clumped
Uniform
Random
Sampling techniques
Random Sampling
systematic sampling
Voluntary sampling
Quadrat samping
Why can the population rate be different?
Sample sizes
The earth’s systems
Geosphere
Hydrosphere
Biosphere
Atmosphere
Anthrosphere
Inputs
What goes into a system
Outputs
What goes out of the system
Open System
They have both inputs and outputs
Closed System
Have limited inputs and outputs/only the air can be exchanged
Isolated System
inputs are outputs are contained
2 population patterns growth
Exponential Growth
Logistic growth
When does Exponential growth occur?
It occurs when there is no predators, no competitions, enough space, plentiful resources, more births than deaths.
When does Logistic growth occur?
It occurs when the the resources are running low.
Carrying Capacity
The max amount that the environment can handle
What can change the carrying capacity?
A natural disaster
Independent limiting factors
Weathers, natural disasters, human activities
Ecosystem
A complex relationship with the organisms and the environment.
Disturbance
Anything that can cause a change in the environment
Physical Agent
Destroying things
Chemical Agent
chemicals killing life
Biological Agent
introduction of life
Example of natural disturbances
Droughts, tsanami, tornadoes, Earthquakes, volcanos, and floods
Ecosystem stability
The ecosystem are flux because temperatures change and rainfall change.
Resilience
The ability of an ecosystem to bounce back after a disturbance
Genetic Diversity
How much variation in the DNA is among a group of species.
Resistance
The ability of an ecosystem to resist change caused by a disturbance.
Ecology Succession
a series of biotic changes that occur on a plain land to make a community.
2 types of Ecology succession
Primary succession
Secondary succession
