Ecosystem is that it is a community or group of living organisms that live in and interact with each other in a specific environment.
For instance, tropical forests are ecosystems made up of living beings such as trees, plants, animals, insects and micro-organisms that are in constant interaction between themselves and that are affected by other physical (sun, temperature) or chemical (oxygen or nutrients) components.
An ecosystem consists of a community of organisms together with their physical environment.
Ecosystems can be of different sizes and can be marine, aquatic, or terrestrial. Broad categories of terrestrial ecosystems are called biomes.
In ecosystems, both matter and energy are conserved. Energy flows through the system—usually from light to heat—while matter is recycled.
Ecosystems with higher biodiversity tend to be more stable with greater resistance and resilience in the face of disturbances, or disruptive events.

Answer:
The cell membrane of the living organism is made of the lipid bilayer and proteins. The most common lipid present in the plasma membrane is the phospholipids.
Phospholipids has both the hydrophobic tail and hydrophilic head. The hydrophobic region interacts with each other. The lipid layer of phopholipids gets in association with the hydrocarbon chain of triglycerides. Their hydrophilic part dissolve in each other.
