Question

How do organisms in an ecosystem interact & how their actions affect other organisms in an ecosystem?

thanks if u answer!(:

Answers

Organisms interact in many different ways, but all in all the stability of any ecosystem relies on these interactions, the specific effect on other organisms depends on the interaction.

Organisms live off of eachother... and the depletion or abondance of any one specific organism will always play some role in another that depends on it for either food or population controle. EX: The snakes that are being wrongfully released into florida have no natural enemies and therefore are reproducing at a rapid rate and are putting a small field mouse native to florida in danger of extintion... and of course there are other organism that depend on the field mouse and so on and so on, causing 'instability'.

I'm not sure if that's the kind of answer you were looking for but I hope it helps. :)

Species Relationships

* Species relationships are the interactions that allow organisms to obtain energy and materials necessary for life processes

* These interactions also maintain homeostasis within ecosystems

Feeding Relationships: How organisms obtain energy

* Feeding relationships reflect organisms roles in the community

* All non-autotroph organisms depend on autotrophs for energy

* These non-autotrophs are called heterotrophs

* Heterotrophs can't make their own food and are also called consumers

* Consumers that eat only plants are herbivores

Carnivores and scavengers

* Consumers that eat only other consumers are called carnivores

* Consumers that eat only dead animals are scavengers

* Scavengers are actually a huge part of the ecosystem

Omnivores and Decomposers

* Consumers that break down dead organisms are decomposers

* Consumers that eat both plants and animals are omnivores

Close Relationship for survival

* The different types of relationships in a group are called symbiosis

* The first type of relationship is commensalism; which is a relationship where one species benefits and the other is not afected

* The second type of relationship is mutualism; which is a relationship where both species benefit

* The third and final type of relationship is parasitism; which is a relationship where one species benefits and the other is harmed

Matter and Energy in Ecosystems

* Matter and energy are constantly cycling through stable ecosystems

Food Chains: Pathways for matter and energy

* Food chains are simple models that show how matter and energy move through an ecosystem

* Food chains can have three links but no more than five links

* Energy is lost at each link which is why there can only be five links
