Food chains and Food webs
This provides energy to all food webs on earth
what is the sun
the rule of how much energy is transferred from one trophic level to another
what is the 10% rule
all the populations of all the different species that live together in a particular area
what is symbiosis
The role and space that an organism fills in an ecosystem
what is a Niche
An organism that has an outsized ecological impact on a ecosystem
What is a Keystone species
The mass of all the organisms in that trophic level
what is biomass
The most abundant trophic level in a food chain
what is a producer
Two cats fighting
what is intraspecific interaction
Where it is possible for an organism to live and its role in the ecosystem
what is a Fundamental Niche
Addition or removal of a top preditor of an ecosystem
What is a Trophic Cascade
The value of the total photosynthetic rate minus the respiration rate
what is net photosynthetic rate
The most common ways energy is used at a trophic level
Cows are unable to digest cellulose in grass. Bacteria in the cow’s gut assist the cow in digesting cellulose and the bacteria gets food in return
what is obligate mutualism
Division of limited resources by a species to help avoid competition
what is Resource partitioning

what is amensalism
Two birds feed on small invertebrates lodged on small bark crevices on the same tree but do not complete for the same food resource
What is different niche in the same habitat
Kelp -> Sea urchin -> Sea Otter -> Orca. I have the biggest affect on this food chain
What is a Sea Otter
An animal that eats both animals and plants
what is a omnivore
use detritus as an energy source
what is a decomposer and detritivores

what is Gauses law of competitive exclusion
Has a limited or narrower niche
What is a specialist
