population defintion
Group of the same kind of organisms in an area
competition defintion
When two organisms want a resource that is a limited amount of
ecosystem defintion
Groups of living things interacting with one another and their physical environment
biotic definition
Any Living thing or once living
abiotic defintion
Non-living
flucuate defintion
Small increases and decreases over time
stable/healthy population
A population that stays around the same number
trend defintion
A pattern
How can we identify things in an ecosystem as either biotic or abiotic?
Biotic is living or once living, abiotic is non-living.
What would happen if orangutans (or other organisms) do not get enough food (or resources) from the available resources?
They will die because they won’t have enough energy for stored fat, growth, and energy.
What is the relationship between resource availability and survival if there are not enough resources?
not enough resources = more competition, some orangutans may not get the energy/food they need to survive.
What is the relationship between resource availability and survival if there are enough resources?
enough resources = less competition, most orangutans get enough resources to survive.
What is the relationship between the amount of resources available and the population size if there are more resources available?
more resources available = increase in the population size for orangutans, at some point, the increase levels off/plateaus.
What is the relationship between the amount of resources available and the population size if there are more resources available?
more resources available = increase in the population size for orangutans, at some point, the increase levels off/plateaus.
What is the relationship between the amount of resources available and the population size if there are not enough resources available?
decrease in resources available, = decrease in the population size of orangutans.
what does it mean when a trend is going downward overtime?
A trend downward over time is not a typical fluctuation, and means the population is not stable. A trend over time means the population is increasing above its typical size.
What is the relationship between the amount of resources and competition when there is more resources
When there are more resources, there is less competition for the orangutans.
What is the relationship between the amount of resources and competition when there is less resources
When there are less resources, there is more competition for the orangutans.
What does the term ”healthy” population/stable population mean?
A healthy and stable population is a population that stays around the same number.
is it unusal for population sizes to flucate?
not unusual for population sizes to fluctuate, a healthy population fluctuates.
what pattern is there when there is an increase in population numbers
population numbers increase= competition increased = some orangutans to get less food and die.
what pattern is there when there is a decrease in population numbers
population numbers decrease= competition decreased= some orangutans to get more food and possibly reproduce.
What is the relationship between the size of the population of orangutans (or other organisms) and chances of survival?
When there are more orangutans, there is more competition, which leads to some not getting fruit/energy and possibly dying.
With fewer orangutans, there is less competition, which leads to getting enough fruit/energy and more surviving.
What are the effects of minor (small) and major (large) disruptions on a population?
Minor disruptions in resource availability may lead to small fluctuation in population size.
Major disruptions in resource availability may cause the orangutan population to increase or decrease drastically in numbers.
