Abiotic/Biotic Factors
Is water abiotic or biotic?
Abiotic
A bird building a nest in a tree is a common example of this symbiotic relationship
Commensalism
The smallest unit of ecological study, referring to a single living thing
This type of interaction involves one animal hunting and eating another.
Predation
These are the non-living components of an ecosystem, such as sunlight, water, and soil.
Abiotic Factors
A symbiotic relationship where both organisms benefit, such as bees and flowers.
Mutualism
All members of the same species living in the same place at the same time.
Population
In parasitism, the parasite benefits while this other organism is harmed.
Host
These are the living or once-living parts of an ecosystem, such as plants, animals, and bacteria.
Biotic Factors
In this type of relationship, the host is harmed while the parasite benefits
Parasitism
A level of organization composed of different populations living together in a defined area.
Community
If a herd of deer increases, this biotic factor—the availability of food—will likely decrease.
Competition
What does the term "biotic" mean?
Living or once living
A symbiotic relationship that only one benefits from but neither is harmed.
Commensalism
The highest level of organization that includes all areas of Earth where life exists.
Biosphere
Because the bee gets nectar and the flower gets pollinated, this is the type of relationship they share.
Mutualism
What does the term "abiotic" mean?
Not living
The interaction between two organisms
Symbiotic Relationship
Place these in order from smallest to largest: Community, Biosphere, Population, Organism, Ecosystem.
Organism, Population, Community, Ecosystem, Biosphere?
When birds defend there territory from other birds, is that competition?
Yes
