1 Relationships in Ecosystems

2 Competition All living things compete for
Food Space Competition limits population growth

3 Symbiosis Any close relationship between species en.wikipedia.org

4 Mutualism A relationship in which both species benefit Pollination

5 Commensalism A relationship in which one species benefits and the other is neither helped nor harmed Shark & remora Barnacles on whale

6 Parasitism A relationship in which one organisms benefits and the other is harmed Mistletoe Tick

7 Predator - Prey Predators are consumers that capture and eat other consumers, called prey

8 Cooperation Organisms working together toward a common end or purpose

Biotic Relationships:

Biotic Relationships:
Relationships in Ecosystems. Populations All of the same species in an ecosystem www.nkf-mt.org.uk www.intrasystems.gr.

Shaping an Ecosystem. Biotic and Abiotic Factors Ecosystems are influences by living and non living Biotic factors: all biological factors in an ecosystem.

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

* 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.

 All living things interact with their environment, both biotic and abiotic  Most living things produce more offspring than can survive.
