Competition
In this type of competition, the organisms belong to the same species.
What is intraspecific competition?
One organism hunts, kills, and eats another organism.
What is predation?
What is mutualism?
Two bears fight over access to the same food source.
Intraspecific competition
What are the three major categories of interactions we studied?
Competitive, consumptive, and symbiotic interactions
Two moose of the same species compete for a mate. What subtype of competition is occuring?
What is intraspecific competition?
A deer eating leaves from a will tree is an example of this interaction.
What is herbivory?
One organism benefits while the other is neither helped nor harmed.
What is commensalism?
Predation
Which interaction can be represented as +/+?
Mutualism
A wolf and a fox compete for the same prey. What subtype is this?
What is interspecific competition?
A tick feeds on a moose while harming the moose.
What is parasitism?
One organism benefits while the other is harmed.
What is parasitism?
A barnacle attaches to a whale and gains transportation while the whale is unaffected.
Commensalism
Which interaction can be represented as -/-?
Competition
In this type of competition, the organisms competing belong to different species.
What is interspecific competition?
Identify the predator and prey: An owl catches and eats a mouse.
Owl = predator
Mouse = prey
A bee gets food from a flower while helping pollinate the flower.
What is mutualism?
Two different species of birds compete for nesting spaces.
Interspecific competition
A student says "All competition happens between different species." Explain why the student is incorrect.
Competition can occur within the same species (intraspecific) or between different species (interspecific)
Explain the difference between intraspecific and interspecific competition.
Intraspecific competition occurs within the same species; interspecific competition occurs between different species.
What do predation, herbivory, and parasitism have in common?
One organism benefits by consuming all or part of another organism, while the other organism is harmed.
Mutualism = both benefit (+/+)
Commensalism = one benefits and the other is unaffected (+/0)
Parasitism = one benefits and the other is harmed (+/-)
A tapeworm obtains nutrients from its host, harming the host.
Parasitism
Two different species of birds compete for berries. A hawk then catches and eats one of the birds. Identify both interactions occurring.
Interspecific competition between the birds and predation between the hawk and bird.
