<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:
A food web consists of many food chains. A food chain only follows just one path as animals find food. eg: A hawk eats a snake, which has eaten a frog, which has eaten a grasshopper, which has eaten grass. A food web shows the many different paths plants and animals are connected.

Answer: All of these choices are correct.
Explanation:
Paired box 6 also known as Pax6 is an evolutionarily conserved transcription factor that plays a major role in the development of the vertebrate eye and the central nervous system. Mutations in mammalian Pax6 are characterized by eye defects, e.g (congenital cataracts, as well as Central Nervous System disorders like microcephaly, dysgenesis, neuron to glia transformations, etc.) Many studies have demonstrated the importance of Pax6 to vertebrate cell differentiation, proliferation, patterning. etc
Pax6 have the tendency to activate multiple genes. For example, if two fly Pax6 genes, eyeless (ey) and twin of eyeless (toy), (initiate eye specification), and, eyegone (eyg) and the Notch (N) pathway, (independently regulate cell proliferation). Pax6 have the tendency to controls eye progenitor cell survival and proliferation through the activation of eyegone (eyg) , thereby indicating that Pax6 initiates both eye specification and proliferation.
Also, Pax6 is considered to be the master control gene for eye development in all seeing animals. In vertebrates, it is required not only for lens/retina formation but also for the development of the central nervous system.
The statements the describe the ecosystems are the following:
1. Balance is required for the survival of an ecosystem.
2. One way to determine an ecosystem's health is by its biodiversity. Biodiversity means having different kinds of plants and animals in an ecosystem.
3. Predators play a role in balancing the earth's ecosystems. These animals are essential in maintaining the food pyramid or the food chain.
