Cell is the basic unit of life while organs are the group of tissues formed from cells.
One example is the neuron, a cell that composes the nervous system. For example a brain, an organ composed of thousands of neural fibers and glial cells that performs many important organismic functions.
Neurons are specialised cells that have dendrites, axons and terminal buttons that sends and receives stimuli from the environment and transduces it into a meaningful information and understand the complexities which the brain now functions.

<u>Answer</u>: A food web is a graphical representation of interconnected food chains.
A desert food web will have as producers the cacti, annual flowers and sagebrush. Some of the primary consumers of these food web are the ants, lizards and pronghorn.
Secondary consumers are the scorpions, snakes and wolves. The haws represent tertiary consumers and in some instances they may even eat wolves, especially unprotected cubs.
The energy flows through the food web from inorganic components such as the sun, nutrients, water into the producers. Then primary consumers eat the producers and are in turn eaten by the secondary consumers. The tertiary consumers will feed on both primary and secondary consumers.
<u>Notes</u>:
Please find attached all the necessary files with the exception of the desert flowers (due to maximum numbers of attached files restriction). These images are not copywrighted and thus free to use.
I have created the required table as an Excell document in case you need to modify it. I did not add the images for the species in the Excell table.
I have also created a more exensive food web (described in the Answer section) for your desert habitat.
As I had some difficulties in understanding the last part of your question, please let me know in a comment if you require additional modifications. I have saved the foodweb PSD file as well as he Excell file.
Answer:
It is the brain of the cell and it tells the other cell parts what to do.
It holds the cell's DNA
