Ecosystem Resilience
The ability of an ecosystem to resist/withstand change.
Ecosystem Resilience
All living and nonliving factors in an area.
What is an ecosystem?
What are non-living factors, such as sunlight, temperature, and soil quality, called?
Abiotic Factors
The type of species that prepares the environment for more complex organisms by breaking down rock.
What are lichens
Human activities like this can destroy a climax community
Deforestation/Pollution
When one species is lost, another with a similar role may step in to maintain balance.
Functional Redundancy
When plants and animals first colonize a barren, lifeless habitat
Primary Succession
What term describes the variety of different species in an ecosystem?
What is Biodiversity?
An organism's role and how it interacts with its environment.
What is a niche?
What term describes species that humans introduce that outcompete native species?
Invasive species
A stable, mature ecological community that represents the final stage of succession, characterized by a balanced mix of plant and animal species adapted to their environment.
Climax Community
What is one natural disturbance that can restart succession.
What is a fire, flood, drought, hurricane, or tornado?
This rapid environmental change happens when a species' natural habitat is destroyed.
What is habitat loss?
What is carrying capacity?
What is one example of a sustainable system mentioned in the previous lesson?
Green roofs or permeable pavements
Species that are the first to colonize newly created environments
Pioneer Species
Occurs when toxins build up, or accumulate, in a food chain.
Bioaccumulation
When pollutants accumulate in organisms at higher levels of a food chain.
What is biomagnification?
Maintaining ecosystems resources for the future
What is sustainability?
What is the Tragedy of the Commons?
Overuse shared resources
This type of species, like wolves or sea otters, has a major impact on ecosystem stability and resilience
When the recovery of an existing biological community after a disturbance sets it back to an earlier ecological stage.
Secondary Succession
A permanent or long-lasting shift in an ecosystem ccaused by climate change, invasive species, human activity.
What is ecological disruption?
One benefits, the other is harmed.
What is Parasitism?
What must be considered when designing an ecological solution?
Trade-offs, cost, time, and long-term success
