Living organisms depend on other living organisms as food sources. AN overpopulation of a certain living organism or a decrease in a population of an organisms may unstable the other organisms that depend on it for food.
Living things in the ecosystem must associate with other organisms for its better life for example relationships such as symbiosis,parasitism,commelsalism between two organisms provide food and protection for them although the host in paratism is harmed,another point is the fact that all organism depend on this tiny things(decomposers)which treat dead organisms and produce nutrients used by plants,plant eaten by herbivores and veggies eaten by carnivores.What i try to stress is that organisms depend on each other for food,protection,etc. Humans have also contributed a lot many of our homes are inhabited by pests(shelter),many of our gabbages provide food for them...

animals and plants
Organisms depend on inorganic and organic factors. Organic factors are things that come from food like protein fat and carbohydrates. Inorganic factors are other things like water, oxygen, and salt.
Producers do not depend on other organisms in quite the same was as consumers do. They depend directly on the sun for energy. Other organisms do influence producers though, such as fellow producers competing for sunlight (blocking out from other producers) as well as consumers, which are a danger to producers.
