Risks
The unfavorable effects of the solution.
Engineering Design Process
A method used to develop or improve technology.
Benefits
The favorable effects of the solution.
Technology
The application of scientific knowledge for practical purposes
Criteria
The set standard on which a solution can be based.
Constraints
The limitations that a design or solution must stay within.
tradeoff
An exchange for one thing in return for another.
Iterative
the use of repeated steps
Prototype
The first build of a design, it may not be built to scale or within the final materials.
Decision Matrix
This is where each criterion is given a number, or weight, based on how important that criterion is.
resilience
the ability of an ecosystem to recover after it has undergone a disturbance
ecosystem
is a complex relationship between organisms and their environment
disturbance
refers to anything that causes change to the environment
natural disturbances
caused by nature
human-caused disturbances
caused by humans
resistance
the ability of an ecosystem to resist change caused by disturbances
ecological succession
a series of biotic changes that occur on bore land to create a community
primary succession
when an ecosystem is created from bare rock
secondary succession
when an ecosystem is developed on bare soil
stable ecosystem
can bounce back from “normal” disturbances
genetic diversity
how much variation in DNA is among a group of species
Density
how much matter is in a given space
population density
how many individuals are living in a given space
population dispersion
refers to how organisms seperate themselves within a population
clumped
occurs when resources are spread unevenly
uniform
occurs when individuals compete
random
when individuals are spread randomly
exponential growth
any group of organisms that has an ideal amount of resources, it occurs when organisms move into an uninhabited area
logistic growth
occurs when populations are running low on resources, the growth of a population levels off to the size that the environment can support
carrying capacity
the maximum number of individuals that the environment can sustain and support
limiting factors
factors that can affect the carrying capacity
density-dependent limiting factors
includes predation, competition, and parasitism
density-independent limiting factors
includes weather, natural disasters, and human activities
systems
a set of interacting components or parts
inputs
what goes into a system
outputs
what comes out of a system
opened system
both inputs and outputs flow in and out freely (both energy+matter)
closed system
the flow of input and output is limited (only energy is exchanged)
isolated system
inputs and outputs are contained (ice cooler)
biotic factors
living or once living components
abiotic factors
non-living components like energy and matter
habitat
include both biotic and abiotic factors where the organism lives
ecological niche
an environment that includes everything that the organisms need to survive and reproduce
predation
when one organism captures and eats another organism
competition
when an organism competes for limited resources
symbiosis
relationship between different organisms like mutualism, commensalism, and parasitism
