Definitely on the right lines Christopher. You would be amazed at the huge number of micro-flora and fauna in the soil - fungus, bacteria and animals all of which do a job - releasing nitrogen, phosphorous and potassium to feed the plants, helping create root systems, helping the plant take up nutrients and water, protecting the plant from predators. Once pesticides and insecticides are used, or artificial NPK fertilizer (fertiliser with artificially added Nitrogen (N), Phosphorous (P) and Potassium (K), these beneficial micro-flora and fauna are destroyed. For instance, if you use artificial fertilizer, the soil loses its ability to create it's own NPK and you are then totally reliant on the artificial fertilizers going forward. For this reason, a lot of people who decide to go organic don't have very much success in the first couple of years unless they do a huge amount to improve the soil with compost, manure and natural fertilizers, because the soil has been destroyed. As for pests, in a natural environment, every pest has got a natural predator, but of course being a single organic garden in the midst of non-organic gardens, a lot of those predators have unfortunately been eliminatedby insecticides, so you have to get creative and it usually involves a lot of picking off by hand and squashing unfortunately!
