Vocab For Chapter 1 Flashcards
defined biotic and abiotic
Biotic- living abiotic-non living
what is environmentalism?
Environmentalism is a social movement that seeks to protect the environment.
what is an ecosystem
an ecosystem is a particular location on earth with interacting components including biotic and a biotic
what is environmental science
environmental science is that discipline that examines interactions among human and natural science systems
what is a system
Any set of interacting components that influence one another by exchanging energy, materials or information.
what is environmental indicator
They described the current state of an environment system.
what are ecosystem services
The process by which life supporting resources, so just clean water and agricultural crops are produced.
what is the difference between bio diversity, genetic diversity and species diversity
Bio diversity is the diversity of life forms in an environment.
Species diversity is the number of species in a region or particular ecosystem.
Genetic diversity is a measure of genetic variation among individuals in a population.
what is a species
species are a group of organisms that is distinct from another group and its morphology, aka body form in structure behavior or biochemical properties
define- speciation and background extinction rate
Speciation is the evolution of new species.
Background extinction rate is the average rate at which species become extinct over the long term.
Define anthropogenic.
derived from human activity
defined sustainability and sustainable development
Sustainability- is the ability to live on earth using Earth’s resources without depriving future generation, those same resources.
Sustainable development -is development that balances current human well-being for the benefit of future generations with resource management.
defined biophilia.
Love of life.
What is an ecological footprint?
A measure of how much an individual consumes expressed in an area of Land.
define replication and theory
Replication-The data collection procedure of taking repeated measurements
Theory- a hypothesis that has repeatedly tested and confirmed by multiple groups of researchers and has reached wide acceptance
defined natural experiment
A natural vent that acts as an experimental treatment in an ecosystem
what is the scientific method and what are the stages of it
Observing question for a test of a hypothesis, collect data, interpret results, disseminate findings
The method is to explore the natural world, draw inferences from it and predict the outcome of certain events. Processes are changes.
give 3 examples of a test of a hypothesis
What makes one plant species more likely to persist than other plant species
Certain animal species will be able to tolerate chocolate.
Animals can learn some human behavior.
what is the difference between independent and dependent variable
dependent variables are variables are dependent on other factors, while independent variables are not dependent on other factors
what is an null hypothesis
Null hypothesis of protection that there is no difference between the groups or treatments that are being compared.
define sample size
Sample size is the number of times and measurement is replicated in a data collection.
define accuracy,precision, and uncertainty
How close the repeated measurements of a sample are to one another is _precision
accuracy -is how close a measured value is to the actual or true value
uncertainly- is an estimate of how much a measured or calculated value differs from a true value.
defined natural experiment
A natural experiment, occurs when a natural event acts as an experimental treatment in an ecosystem. for an example, the volcano that destroyed thousands of acres of forest provides a natural experiment for understanding large-scale forest regrowth
