Taxonomic classification system from least to most specific
What is domain, kingdom, phylum, class, order, family, genus, species?
Bees and flowers are an example of this relationship
What is mutualism (type of symbiosis)?
Organisms that eat herbivores

What are organisms that are eaten?
The domain and kingdom of multicellular eukaryotes that are heterotrophic and contain a cell wall
What are Eukarya (domain) and Fungi (kingdom)?
The domain containing prokaryotic organisms that contain peptidoglycan in their cell wall
What are Bacteria?
Lice living on a kindergarten girl's head is an example of this relationship
What is parasitism (type of symbiosis)?
Organisms that eat producers
What are primary consumers / herbivores / organisms in the second trophic level?
These organisms recycle nutrients back into the ecosystem
What are decomposers?
The domain and kingdom of unicellular eukaryotes
What are Eukarya (domain) and Protists (kingdom)?

What is competition?
Organisms that eat carnivores
What are tertiary consumers / carnivores / organisms in the fourth trophic level?
This increases an ecosystem's stability and resilience
What is high biodiversity?
The domain and kingdom of multicellular eukaryotes that are autotrophic
What are Eukarya (domain) and Plants (kingdom)?

What are Archea?
When this relationship occurs, the populations of 2 species fluctuates in a distinct pattern over time
What is predation?
Don'f fit well into any specific trophic level
What are decomposers?
This occurs to the total usable energy in the ecosystem as it transfers between trophic levels
What is a decrease in usable energy? (90% of energy lost as heat)
