Living systems are life forms (or, more colloquially known as living things) treated as a system. They are said to be open self-organizing and said to interact with their environment. These systems are maintained by flows of information , energy and matter .
All living organisms pursue their own "good" in their own ways. Human beings are not inherently superior to other living things. [8] The most important of these four main pillars is likely the idea that human beings are not inherently superior to other living things. People have divergent views on many specific aspects of almost everything.
The human ecosystem concept is then grounded in the deconstruction of the human/nature dichotomy, and the emergent premise that all species are ecologically integrated with each other, as well as with the abiotic constituents of their biotope.

[51] Even with cooperation of the human element of the equation, reconciliation ecology can not help every species.
Beneficial insects can include predators (such as ladybugs) of pest insects, and pollinators (such as bees, which are an integral part of the growth cycle of many crops).). Increasingly certain species of insects are managed and used to intervene where natural pollination or biological control is insufficient, usually due to human disturbance of the balance of established ecosys
