Current potential niche space of the butterfly Titania fritillary (Boloria titania) and its host plant American bistort (Polygonum bistorta) Relationship between. Highlights. •. Relationships between ecosystem services (ES) were analyzed across case studies. •. For many pairs of ES a dominant relationship was identified. An ecological relationship is the relationship between an organism in its ecosystem. All organisms in an ecosystem are connected in one way or another.
A well-known example exists in the mutualistic relationship between alga and fungus that form lichens. The photsynthesizing alga supplies the fungus with nutrients, and gains protection in return.

The relationship also allows lichen to colonize habitats inhospitable to either organism alone. In rare case, mutualistic partners cheat. Some bees and birds receive food rewards without providing pollination services in exchange. These "nectar robbers" chew a hole at the base of the flower and miss contact with the reproductive structures.
As an example, cattle egrets and brown-headed cowbirds forage in close association with cattle and horses, feeding on insects flushed by the movement of the livestock.
The birds benefit from this relationship, but the livestock generally do not. Often it's difficult to tease apart commensalism and mutualism.
When they compete for new territory by arriving there first, it is called preemptive competition. An example is lions and hyenas that compete for prey.
Commensalism Commensalism is a relationship in which one organism benefits while the other is neither helped nor harmed. Examples are barnacles that grow on whales and other marine animals. The whale gains no benefit from the barnacle, but the barnacles gain mobility, which helps them evade predators, and are exposed to more diverse feeding opportunities.

There are four basic types of commensal relationships. Chemical commensalism occurs when one bacteria produces a chemical that sustains another bacteria. Inquilinism is when one organism lives in the nest, burrow, or dwelling place of another species. Metabiosis is commensalism in which one species is dependent on the other for survival.
Phoresy is when one organism temporarily attaches to another organism for the purposes of transportation.

Parasitism Parasitism is a relationship in which one organism benefits and the other organism is harmed, but not always killed. The organism that benefits is called the parasite, and the one that is harmed is the host. The study of the interrelationships between living organisms and the living and non-living components and processes in an environment Biome: A major ecological region within which plant and animal communities are similar in general characteristics and in their relationships to the physical environment.
The collection of all living organisms in a geographic area, together with all the living and non-living things with which they interact.Ecosystem Relationships
A group of organisms of the same kind living in a given area Natural Community: Populations of different plant and animal species interacting among themselves in an area. The specific physical location where a particular organism lives or is adapted to live in a community. The single abiotic factor most lacking in a particular environment is termed a Limiting Factor.

The variation in physical factors that a population can withstand and continue to thrive in an environment is termed Range of Tolerance. Green plants that carry on photosynthesis.
Producers are termed auto-trophs because they are self-nourished — they do not depend on other species to feed.
During photosynthesis, plants capture light energy with their chlorophyll and use it to convert carbon dioxide and moisture absorbed from air into sugar chemical energy.
