they depend for food
All organisms are inter dependent on each other
five ways that humans are dependent on other species because humans need them for shelter, food, fresh air, medicine and clothes.
A dependent relationship in an ecosystem may be in various forms. This may be parasitic where only a parasite is dependent on the host or symbiotic where both organisms depend on each other.
they eat by photosynthesis or by other organisms......

Food and Oxygen
The extinction rates of terrestrial and freshwater organisms varies per location. This is largely dependent on other growing and declining populations.
Parasites are organisms that live inside humans or other organisms who act as hosts. They are dependent on their hosts because they are unable to produce food or energy for themselves.
pooping it out
Energy stored from dead organisms can be used in two ways. They can either be eaten by other organisms or decomposed by bacteria with the nutrients absorbed in the soil to be used by plants.
Living things interact in a number of ways. They have symbiotic relationships that can either hurt or be good for the organisms. Most organisms also produce products that other organisms need.
There is no such thing as a group of 'independent' organisms. All organisms are inter-dependent, like it or not. For example, we are dependent on plants and animals for food.
