6.6.2 interactions between populations Flashcards
What is the definition of intraspecific competition?
Competition within individuals of the same species
Define interspecific competition
Competition between individuals of different species
In a standard in interspecific graph, what is the first out of 5 steps?
Start: population of prey rises
- My way, or the highway population of prey rises few predators eat them.
What is the second step out of five?
Available
^^
- As the pray increases predators, follow the rise as more food is available.
What is the third step out of five?
Prey..
Play population decreases
what is the fourth step out of five?
Predictors
Predator population decreases as the last few days available
What is the last step 5/5?
360 (happens again)
Prey population increases again
What are the characteristics of intraspecific competition?
Adapted
Competition
•Individuals best adapted will survive
•Decreases population size as competition increased
•As competition decreases population size increases .
Basics of interspecific competition?
Pop size
Overlapping
Population size of competing species will overlap
