Population Dynamics
If the birth rate is greater than the death rate, the size of the population will do this.
What is Increase?
A relationship between 2 organisms.
What is symbiosis?
The symbol that shows energy flow in a food web.
What is an arrow?
The type of model that shows the interconnectedness between predator/prey relationships.
What is a food web?
A reason why biodiversity is important for ecosystem health.
What is it makes ecosystems resilient?
The term used when organisms exit a population
What is emigration?
When one organism benefits and another organism is harmed.
What is parasitism?
The direction the arrow in a food web points.
What is from prey to predator?
The amount of energy transferred from one trophic level to the next.
What is 10%?
Organisms that can eat both plants and animals.
What are omnivores? What are primary and secondary consumers?
This type of growth curve is S shaped.
What is logistic growth?
When both organisms benefit.
What is mutualism?
The trophic level with the most amount of energy.
What are producers?
The type of model that shows the relative amount of energy at each trophic level.
What is an energy pyramid?
The type of sphere that includes all living and non-living things in the water on Earth.
The maximum size of a population at which an ecosystem can support.
What is carrying capacity?
When one organism benefits and the other is neutral.
What is commensalism?
The trophic level with the least amount of energy.
What are apex / high order predators?
A limitation to a food chain model.
What is too simple? What is does not show interconnectedness? What is does not show biomass?
What are invasive species?
The factors what can cause a population to decrease. List at least 4.
What is: decreased birth rate, increased death rate, more competition, more disease, emigration, human activity, less resources?
When one organism pretends to look like another for increased chance of survival.
What is mimicry?
If the producers in an ecosystem have 600 kcals of energy, the amount of energy transferred to the secondary consumers.
What is 6 kcal?
A model used to show the relative amount of organic material within living things.
What is a biomass pyramid? What is a trophic pyramid?
Three reasons invasive species are able to take over an area.
What is:
-No natural predators
-Perfect environmental conditions
-Plenty of resources
-No disease/competition
