A relationship in which two different organisms live in close association with each other.
What is symbiosis?
100
Food, water, shelter and food
What are 4 survival needs (limiting factors)?
100
The study of the interactions of living organisms with one another and with their environment.
What is ecology?
200
An organism that makes its own food.
What is a producer (autotroph)?
200
The fourth level of the energy pyramid are made up of these third level consumers.
What are tertiary consumers (3rd level heterotrophs or top carnivores)?
200
A relationship between two organisms in which one organism benefits and the other is unaffected (win-draw).
What is commensalism?
200
The largest population that an environment can support at any given time.
What is carrying capacity?
200
The non-living part of the environment, including water, rocks, light, and temperature.
What are abiotic factors?
300
The third level of consumers that eat both primary and secondary consumers.
What is a tertiary consumer?
300
The third level on the energy pyramid are made up of these consumers that prey on herbivores.
What are secondary consumers (carnivores, ominivores, second level heterotrophs)?
300
A relationship between two species in which both species benefit (win-win).
What is mutualism?
300
Any biotic or abiotic factor that might affect the size of a population.
What is a limiting factor?
300
A group of organisms of the same species that live in a specific geographical area.
What is population?
400
These organisms eat only producers.
What are primary consumers?
400
These make up the second level of the energy pyramid.
What are primary consumers (herbivores or 1st level heterotrophs)?
400
A relationship between two species in which one species benefits and the other is harmed.
What is parasitism?
400
Limiting factor that comes into play when there is overpopulation and few resources that the population must share.
What is competition
400
An organism that eats all or part of another organism.
What is a predator?
500
This level of consumer eats the primary consumers.
What are the secondary consumers?
500
The concept that 90% of the available energy is not passed on to the next trophic level.
What is the Rule of 10%?
500
Symbiotic relationship described here: A remora rides around on the bottom of a shark and eats scraps from the shark's prey. The shark is not affected in any way
What is commensalism
500
The development of two species over time that is due to mutual influence, often in a way that makes the relationship more beneficial to both species.
