This term describes how populations are spread across an area and can be even, clumped or random. It is different than Density.
What is Dispersion?
100
In this type of interaction, animals fight for resources such as food/prey, water, living space with other animals.
What is Competition?
100
A group of organisms of the same species that live in a specific geographical area and can interbreed
What is Population?
100
This is the shape of the human Population curve at this time.
What is "J" curve or Exponential growth?
100
Populations that are too big use these things up and leave little for other people to use.
What is Resources-fuelwood and water?
200
This term describes how many offspring each individual in a population can produce.
What is Reproductive Potential.
200
This is a term that describes how some animals eat other animals/prey, this is a natural process that can keep both populations of animals at healthy levels.
What is Predation?
200
This type of growth occurs when the growth rate decreases and stablizes as the population reaches carrying capacity.
What is Logistic Growth?
200
This term describes the road, bridges, schools, public water systems and other public buildings in a community.
What is Infrastructure?
200
Generally, Fuelwood is used by people for these activities.
What is heat, cooking, building?
300
This type of population growth continues to increase and can only occur if there are unlimited food and space and no predators and the curve is "J" shaped.
What is Exponential Growth?
300
In this type of interaction, one species is benefited and another is harmed.
What is Parasitism?
300
Lack of food, lack of living space, disease.
What are Density Dependent Factors that limits population growth?
300
By 2025, this is the predicted human population on earth.
What is about 8 Billion?
300
If there is no fuelwood for cooking food or sterilizing water, this is likely to happen in the population/to the people.
What is diseases, people get sick and die?
400
This type of population growth curve shows a population that grows rapidly at first but then the population level stablizes. This curve is "S" shaped.
What is Logistic Growth?
400
In this type of interaction, two species need each other to survive and the relationship is beneficial to both.
What is Mutualism?
400
An increase in ratio of people that live in a city rather than an rural area. This migration makes roads, schools and stores more populated.
What is Urbanization?
400
These two demographic rates are most related to the overall population size.
What is Birth and Death Rates?
400
This is when people move into the city from the farms and streets, shops, and schools become too crowded.
What is Urbanization?
500
This is the point at which a population cannot grow any faster because it of the limits of food and space and predators in the area.
What is the Carrying Capacity?
500
In this interaction, 1 species needs another species to survive and the other species is not harmed. For example, an orchid grows high on a tree for sun and rain.
What is Commensulism?
500
Land that can be used to grow crops
What is Arable Land?
500
If birth rate and death rate are low and stable, the population size is going to do this.
What is stabilize, stay the same?
500
This is the specific demographic rate that some countries are trying to decrease in order to decrease their population.
