24.2 competition Flashcards
1
Q
what is interspecific competition
A
competition between different species
2
Q
what does interspecific competition result in
A
- reduction of the resource available to both populations
- less food = less energy for growth and reproduction = smaller populations
- less adapted species get outcompeted
- competitive exclusion principle
3
Q
what is the competitive exclusion principle
A
two species compete for limited resources and the one that uses resources more effectively will eliminate the other
4
Q
what is intraspecific competition
A
competition between members of the same species
5
Q
what does intraspecific competition result in
A
- plentiful resource so all organisms have enough to survive = population increases
- more individuals so resources become limited = population decreases
- smaller population = less competition = population increases
