Flyswatter Review
Community - all the populations of organisms inhabiting a common environment and interacting
with one another
Interspecific interactions - occur between populations of different species
Coevolution - a change in one species acts as a selective force on another species
Symbiosis - For at least part of the life cycle, individuals of two or more species interact with
neutral, positive. Or negative effects on each other
Niche - a way of life, or a role in an ecosystem. an organism’s role in the environment (its
profession, not its address)
Fundamental niche - determined by the physiological limits of the organism
Realized niche - the portion of the fundamental niche actually utilized due to interactions with
other species
Interspecific Competition (–/–) - Competition occurs when 2 or more populations overlap in their
niches
Resource partitioning - The subdividing of some category of similar resources that lets
competing species coexist.
Predation (+/–) - consumption of one organism by another
Parasitism (+/–) - specialized predator (parasite) lives on/in its host, not killed immediately
Endoparasitism - live inside host (tapeworms/viruses)
Ectoparasitism - live on surface of host (mosquitoes/aphids)
Commensalism (+/0) - one partner benefits while not harming the other
Mutualism (+/+) - both partners benefit.
Camouflage - A coloration that helps organisms blend it with their surrounding environment.
Warning Coloration - A coloration characterized by conspicuous patterns and colors that
predators learn to recognize and avoid.
Batesian mimicry - Imitate color patterns or appearance of more dangerous organisms
Müllerian mimicry - describes a situation where two or more species have very similar warning
or aposematic signals and both share genuine anti-predation attributes.
Producers - Organisms capable of making their own food.
Primary consumers - Eat plants and capture their energy
Secondary consumers - Eat primary consumers
Herbivores - organisms that eat only plants
Carnivores - organisms that eat only meat
Omnivores - organisms that eat both plants and meat.
Decomposers - break down waste and dead organisms
Trophic Level - The different levels of organisms on a food chain, based on what they consume.
Rule of 10 - Each time an eating event occurs, only 10% of that energy is available for use by
the consuming organism.
Bioaccumulation - The increase of a toxin in an organism over time
Biomagnification - The increase of a toxin in an organism as you go up the food chain.
Invasive Species: a species that is non-native (or alien) to the ecosystem under consideration
and whose introduction causes or is likely to cause economic or environmental harm, or harm to
human health.
Cilia - Hair-like projections used for movement and feeding
Flagella - Whip-like structure used for movement
Pseudopod - A false foot extended by cytoplasm
Algae - A small plant-like protist that can make it’s own food
