In this relationship, one organism hunts and eats another.
What is a predator/prey relationship?
This type of population growth occurs in environments with unlimited resources. This is also unrealistic to maintain.
What is exponential growth
Have a diet of only meat.
What is a carnivore?
The level of organization that includes all members of the same species in close proximity to each other.
What is a population?
This is the maximum population size that a habitat can sustain.
What is carrying capacity?
Natural disasters are an example of this kind of limiting factor.
What are density-independent limiting factors?
This factor describes non-living things in an ecosystem
What is abiotic?
The maximum number of organisms that can be supported in a given environment.
What is carrying capacity?
An organism that recycles nutrients from dead things back into the environment.
What is a decomposer?
These are factors that restrict the total size of a population.
What are limiting factors?
This factor describes a living thing.
What is a biotic factor?
Disease, competition, and availability of mates are all this type of limiting factor.
What are density-dependent limiting factors?
A diagram that shows all possible predator-prey interactions in a community.
What is a food web?
The idea that 90% of energy is lost between each trophic level.
What is the 10% rule?
Ultimate source of almost all energy on Earth.
What is the Sun?
What arrows in a food chain/web represent.
What is the flow of energy?
The trophic level that consists of organisms that eat producers.
What are primary consumers?
90% of energy is lost as this between each trophic level.
What is heat?
Eats only plants and other vegetation.
What is an herbivore?
Population growth that is realistic. The population numbers eventually level off at a carrying capacity.
What is Logistic growth?
This level will have the largest amount of biomass and energy on a trophic level pyramid
What are the producers?
Have a diet of both vegetation and meat.
What is an omnivore?
These are environmental factors that affect populations regardless of the population density (ex. floods, fires, climate change, etc.)
What are density-independent factors?
This type of growth curve can be expected from a population of rabbits that has reached its carrying capacity.
What is logistic growth?
The survivorship curve that best fits an organism who usually makes it near the end of their lifespan before dying. (ex. humans, elephants, dogs)
What is the Type I survivorship curve?
