Relationships in the Ecosystem. What are the types of relationships? 1)Predator / Prey 2)Competition 3)Symbiosis A) commensalism B) mutualism C) parasitism.

Symbiotic Relationships Species interactions. What is symbiosis? Long term partnership between members of different species.

Niches and Community Interactions

* Competition- when organisms of the same or different species attempt to use the same ecological resource Males competing for the ability to mate.

How Do We Relate?. Relationships Many organisms have developed a close relationship with other organisms of different species. These close relationships.

CLEANING SYMBIOSIS

What traits do they share?

Interactions between organisms can influence the traits and behaviors of those organisms RELATIONSHIPS IN THE OCEAN Reproduction Male-Male interactions influence male size Male-Female interactions influence male courtship behavior & traits used in display male lifestyles Parasitism Host-parasite interactions influence traits parasites use to “control” hosts behaviors hosts use to avoid parasites… Mutualism Interactions that can help some species avoid other interactions!
