Got a Niche?
In in these relationships, there are predators and prey.
What is predation?
What is a population?
We cause populations to increase in size.
What is birth rates and immigration?
We cause populations to shrink.
What are deaths and emigrations?
When an ecosystem is devastated by some disturbance, whether natural or human caused, this will allow the ecosystem to return to its pre disturbed state.
What is succession?
This occurs when two or more organisms fight for the same limited resource.
What is competition.
Better than population.. this includes the number of individuals as well as the size of the space; i.e. crowdedness.
What is population density?
Given ample resources, a population exhibit this type of population growth.
What is exponential growth?
These are conditions inhibit the ability of a population to grow; these establish the carrying capacity.
What are limiting factors?
In this relationship one benefits and the other is unaffected.
What is commensalism?
This curve represents organisms in a population that have high survivorship throughout the majority of their lives. Survivorship begins to decrease when the population reaches 50% of its maximum lifespan.
What is Type I survivorship?
This is a type of population growth that begins with rapid growth, but slows and eventually levels off.
What is logistic growth?
The forest fire that ripped through the ecosystem destroyed countless plant and animal lives.
What is a density independent limiting factor?
This type succession can return an ecosystem to its climax community within 50 - 100 years.
What is secondary succession?
In this relationship, both benefit.
What is mutualism?
When members of a population are equally spaced out in an environment.
What is uniform dispersion?
As a population grow, it will eventually reach the maximum amount of individuals that the habitat can support.
What is the carrying capacity?
What is a population crash?
This type of succession is triggered by disasters like: forest fires, tornados, humans clearing forest, etc.
What is secondary succession?
Mutualism, commensalism and parasitism make these up; when two organisms have a close ecological relationship.
What is symbiosis?
When members of a population tend to group together; a herd of gazelles.
What is clumped dispersion?
The human population currently exhibits this type of population growth.
What is exponential growth?
You know this will not be able to be sustained, what are your predictions for humanities near future?
Covid 19 had a huge impact on the vastly large human population; it affected every continent; i.e. it was a pandemic. Covid 19 is this type of a limiting factor.
What is a density dependent limiting factor?
As a glacier melts (retreats), it leaves mounds and mounds of rocks (of various sizes); the melting water washes away all soil that may have been there. Consequently, it takes 10,000 - 100,000 years for this type of succession to establish soil and eventually the climax community.
What is primary succession?
