Ecology Review Flashcards
If an arrow points away from an organism like the following example, monocot –> nematode, what is being eaten?
monocot (arrows point towards the animal doing the eating)
What is the difference between a food web and a food chain?
food web = many food chains tied together
abiotic
the nonliving parts
biodiversity
the variety of different organisms living in an area
biome
an area classified according to the species that live in that location
biotic
the living parts
carnivore
a type of organism that eats consumers
carrying capacity
a species’ average population size in a particular habitat
climate
the long-term, predictable atmospheric conditions of a specific area
commensalism
one organism benefits, the other is not helped or harmed
community
many different populations of different species living together
consumer
an organism that eats or consumes food
decomposer
an organism that breaks down other organisms and recycles their nutrients back into the environment
ecology
the study of the relationship between organisms and their environment
ecosystem
a self-supporting unit of interacting organisms and their environment
habitat
the area where an organism lives
herbivore
a type of organism that eats producers
mutualism
both organisms benefit from living together
niche
the functional role of a species in an ecosystem
omnivore
a type of organism that eats producers and consumers
parasitism
one organism benefits and the other is harmed
population
multiple organisms of the same species living together in a specific area
predator
an organism that primarily obtains food by killing and consuming of other consumers
prey
the organism which the predator eats
