Explain the role of different organisms in the transport of substances.

All living organisms are involved in the transfer of substances and their circulation in nature.
Some of them produce new organic substances, others process them or take part in their processing.
This process is called the circulation of chemical elements and mineral components.
Thanks to this cycle, a balance occurs, which contributes to ensuring the continuation of life for all living organisms.
This suggests the conclusion that absolutely all living organisms are interconnected, and the existence of some is completely impossible without the activities of others.
