QuestionAnswer

Competition occurs when organisms of the same or different species attempt to use the same ecological resource in the same place at the same time
Interspecific competition between different species
Intraspecific competition between members of the same species
resource anything that is required for life; examples are food, water, and nesting sites
competitive exclusion principle no 2 species can occupy the same niche in the same habitat at the same time
According to the competitive exclusion principle, what will happen to one of the two competing species and why? it will be eliminated because of competition
Occurs when 2 or more species that are intense competitors evolve niche differences or anatomical difference that lessen the intensity of the competition character displacement
A pattern of resource use that occurs when species co-exist and each species uses only part of the available resources resource partitioning
Interaction where one organism captures and feeds on another organism predation
The organism in predation that does the killing and eating predator
The organism in predation that is the food prey
Favors adaptations that make organisms better suited for their environment natural selection
a form of deception used by prey as a means of defense against being eaten mimicry
animals that eat plants herbivores
a close and permanent relationship between organisms in a different species symbiosis
both species benefit from the relationship; +/+ mutualism
the relationship between two different species in which one species benefits from the relationship and the other species is neither helped nor harmed; +/0 commensalism
the relationship between two different species in which one species is helped and the other is harmed; +/- parasitism
An external parasite that lives on their host's body and not in it ectoparasite
An internal parasite that lives inside their host's body endoparasite
Example of an endoparasite tapeworm
example of an ectoparasite tick
Five species of birds share a habitat but they feed from different parts of the tree. What is this an example of? resource partitioning
Two species have birds living on different islands have the same beak size. If they live on the same island they have different beak sizes. What is this an example of? character displacement
Do character displacement and resource partitioning lessen the intensity of competition or increase the intensity of competition? lessen competition
Symbiotic relationship where both organisms try to access the same resource competition
What makes a species invasive? it isn't native to the area and it causes harm to the native species
Honeyguide birds eat honey but aren't strong enough to get into a beehive. The honey guide bird will lead the honey badger to the bee's hive, who will break down the hive, and they share the hone. What is the relationship between the honeyguide and the badger? mutualism
A bird has its nest in a tree. What is the relationship between the bird and the tree? commensalism
A spider eats a grasshopper. What type of relationship is this? predation
Orchids grow in tall tropical trees. The trees are not harmed but orchids get sunlight. commensalism
Trout and perch fight over the same nesting sites. What type of relationship is this? competition
A bee gets nectar from a flower and the bee spreads the pollen of the flower to fertilize the flower's ovules (eggs). What type of relationship is this? mutualism
Bacteria living in the intestines of a cow help the cow break down cellulose and also have a home to live in. What type of relationship is this? mutualism
