TROPHIC STRUCTURE and Me
Lord of the SPECIES: Return of the King
100
The feeding relationships between organisms in a community.
What is trophic structure?
100
Species that are most abundant or have the highest biomass.
What are dominant?
200
Daily Double!!! A branching food chain with complex trophic interactions
What is a food web?
200
These species are introduced, often due to human activity, and usually lack natural predators.
What are invasive?
300
These link trophic levels from producers to top carnivores.
What is a food web?
300
These species exhibit a large control over an ecosystem due to their niche, and if lost, can devastate an ecosystem.
What are keystone?
400
The range of number of levels in a simple food web (aside from exceptions)
What is 3 to 5?
400
These species often cause change within an ecosystem that affects community structure and are often called ecosystem "engineers".
What are foundation?
500
In a food web, these organisms feed on dead material, detritus, and link the top levels of a web to the bottom via recycling of nutrients.
What are detritivores (decomposers)?
500
These type of foundation species may have a positive impact on survival and reproduction of various species.
What are facilitators?
