Competition occurs when individuals require a limited supply.
The correct answer is: When two parties want the same things
- Competition is the event where two parties oppose each other for an outcome
- In biological terms, competition between organisms occur to acquire a limited product or material
- There are three types of mechanisms that are observed in biological competitions:
- Interference
- Exploitation
- Apparent competition
- Competition between members of same species is called intraspecific competition and between members of different species is called interspecific competition
