Systems and models
Stores of Matter or Energy
What are Storages
Marine, Freshwater, and Terrestrial
What are the 3 types of ecosystems
living things that are none/slow moving
What are none motile organisms
These are two main human activities that contribute to the destruction of habitats.
What is deforestation and urbanization?
Human activities like building cities, which affect the carbon and nitrogen cycles.
What is urbanization?
Open, closed and isolated
What are the three types of systems
Forests, Tundras, Aquatic (Freshwater and marine), Grasslands and Desserts
What are the 5 major biomes?
Is a square frame to sample, count, and analyze the distribution, frequency, and percentage cover of plants or slow-moving organisms within a defined area.
What is a quadrat?
It measures how fast we consume resources and generate waste, often at times exceeding Earth's capacity.
What is Ecological Footprint
A type of contamination
What is pollution?
The transfers or transformations between storages.
What do flows represent?
A community and the physical environment with which it interacts, linked together by energy and matter flows.
What is an Ecosystem
Used to estimate the population size of motile animals.
What is the capture, mark, re-capture?
The number of deaths per 1000 people per year
What is Crude Death Rate (CDR)?
The process where a pollutant builds up in a single organism or trophic level.
What is bioaccumulation?
Will stabilise the system by increasing a flow that will counteract the change
What is a Negative feedback loop?
The change of an ecosystem over time and is most clearly seen when an environment is low in species diversity and population
What is Succession
To ensure a sample is not biased, these sampling locations should be selected using this method.
What is random sampling?
It is a simplified version of world interactions,
What is a model?
Cannot be broken down by the environment.
What is non-biodegradable?
The minimum amount of change within a system that will destabilize it, causing it to reach a new equilibrium or stable state.
What is a tipping point
The particular set of abiotic and biotic conditions and resources to which an organism or population responds.
What is a Niche?
A tool used to identify unknown species based on a series of choices between alternative characteristics.
What is a dichotomous key?
The maximum population size of a species that a specific environment can sustainably support over the long term without degrading the habitat
What is carrying capacity?
The amount of change a system can take before reaching a new equilibrium or stable state.
What is a tipping point?
