Population
What is a population?
A population is the number of organisms that live in the same area at the same time
What is carrying capacity?
The maximum number of organisms an ecosystem can support
Give an example of a uniformed population?
(any correctly given answer)
What is high population density?
High population density is when organisms live closely near eachother
What makes a group of animals a population?
The animals have to be living in the same area at the same time
What is exponential growth and what shape does it form?
when the population size increases faster as resources remain unlimited, forms a J shape
Give an example of a Random population
(any correctly given answer)
What is low population density?
Low population density is when organisms live far apart in an area
What is immigration?
The movement of individual organisms into a population
What is logistic growth and what shape does it form ?
This S-shaped growth that's occurs when limiting factors slow down a population
What is Uniform Dispersion and why does it happen?
Uniform Dispersion is when organisms are evenly spaced out, it usually happens due to competition or territory
What is population density?
The term for how many individuals are found per unit of area
What is emigration?
When organisms leave a population and move somewhere else (for example birds migrating when it gets cold)
What is the equation for Zero Population Growth? (ZPG, When population stays the same)
Births + Immigration=Death+Emigration
What is a clumped dispersion and why does it happen?
A clumped dispersion is when organism stay in groups to find better protection, or food resources.
What situation has a lower density?
Only 3 penguins live on a huge iceberg, while another iceberg has 20 penguins crowded together.
The iceberg with 3 penguins they are spread out over a larger area.
Why do scientists study populations?
Scientists study populations to better understand how fast they grow, what affects them, and why organisms live in certain areas but no others.
What happens when a population exceeds its carrying capacity?
Starvation, death rates increases, competition etc
What is a Random Dispersion and why does it happen?
Random Dispersion is when organisms have no clear pattern and have no real relation, usually happens when resources are evenly available.
Which situation has a high density
20 kids crowd around 1 small pizza or 20 kids spread out over 5 pizzas.
The first group
