Competition!

Competition • Competition – When organisms fight for the same resources. • E. g. foxes and black bears live in basically the same habitat. • ach survives by having its own niche: eating different food, coping with winter differently, etc. • - Sometimes organisms eat the same food or want to live in exactly the same area.

What kinds of competition can you think of?

Competition 2 types of competition: 1. Interspecific Competition - When two organisms of different species compete. • E. g. Owls and hawks eat mice. If each animal runs out of other food sources they will compete for food. – This could result in some animals not having enough food to survive. – It could also lead to fights between these animals.

Competition 2. Intraspecific Competition - When two organisms of the same species compete. • • E. g. Two lions fighting over a mate This could result in one not being able to have offspring

Competition is considered a “good thing” • It limits or removes weaker organisms and creates a healthier population. • It leads to “survival of the fittest” scenario. • Only those who can out-compete their rivals will live to reproduce and pass their “good” characteristics onto the next generation.
