Interdependence
Ecosystems
| Question | Answer |
|---|---|
| When all organisms of a habitat are linked together and interact with each other | Interdependence |
| The natural physical environment in which a species lives | Habitat |
| It’s a way of describing the life of an organism, What and where it eats, sleeps etc. | niche |
| The maximum number of organisms a particular environment can support? | carrying capacity |
| Organisms are usually most abundant in their? | preferred niche |
| What is a biotic factor | All the living organisms |
| What is a abiotic factor | Non-living or physical factors |
| Name ways organisms survive unsuitable conditions | Migration, acclimation, dormancy |
| The number of organisms of one species in a specified area | Population density |
| Which one of these is not a population? All the birds in the sky, or all the robins in Iowa | All the birds in the sky |
| Name the three distribution patterns | Random, Clumped, Uniform |
| What are the advantages to clumped distribution | Protection, easier hunting |
| What are the advantages to uniform distribution | Less competition for resources |
| An individual of one species eats all or part of an individual of another species? | Predation |
| Close long term relationship between two organisms | symbiosis |
| Relationship in which two species derive some benefit from each other. | mutualism |
| Interaction where one species benefits and the other is not affected | Commensalism |
| Relationship where one organism is harmed and the other organism benefits | parasitism |
| When organisms from two different species want the same food and space | Interspecific competition |
| Name 3 things organisms can compete for? | Space, suitable mates, Food |
| When two organisms from the same species require the same food and space | Intraspecific competition |
| What determines an ecosystems carrying capacity | limited resources |
| Name some Density dependent factor | Food supply, parasites, disease, predation |
| Name some Density independent factor | Rain, drought, flood |
| Areas of an organism's tolerance curve where there will be most competition | Optimal range, preferred niche |
| Where on a tolerance curve (which zone) will an organism experience the worst chance of survival or success? | zone of avoidance or death |
| What are three examples of symbiotic relationships | Mutualism, Commensalism, Parasitism |
| A fox will capture and eat a rabbit is an example of | Predation |
| A heart worm living in a dog, is an example of | Parasitism |
