Both biotic and abiotic factors form an ecosistem. The biotic factors are the living part of it, while abiotic factors are the non-living part (such as sunlight, soil and temperature).
Some of the interactions between these factors that occure and creat the ecosystem are:
Silver maple (biotic) and the sunlight (abiotic): The tree is considered a producer because it uses the sunlight to do photosynthesis converting it into food.
This exact interaction happens between the american beauty berry and the sun, and between the bermuda grass and the sunlight (therefore they are also called producers.
In this case the sun is a source of energy.
The army worm on the other hand is called a consumer (in this case is a primary consumer) because it eats plants from which it obtains nutrients. It is called a primary consumer because it eats producers of energy (plants).
In the picture there is also a secondary consumer (the cardinal) that eats primary consumers, and tertiary consumers (owl, snake and hawk) that obtain energy by eating secondary consumers.
The mushrooms are called decomposers because they break down organic matter from both animals and plants and transform it into nutrients (inorganic compounds) that are later consummed by plants. therefore mushrooms transform the composition of soil (which is an abiotic factor).
When plants (biotic factors) do photosynthesis they consume carbon dioxide to produce oxigen changing the composition of air (abiotic factor). The oxigen in the air is then used by animals to breath.
