According to natural selection, which of the following correctly describes an individual with higher fitness?
Leto [7]

Answer: best adapted to the environment

Explanation: fitness can be thought of as fit for purpose. The most fit for purpose organism is the one best adapted to its environment.

Nevertheless, all the options are characteristic of adaptation

It is not particularly useful to discuss natural selection in terms of individuals and not populations. An advantageous mutation in one individual is the theoretical starting point for a better adapted population, but adaptation happens in a population very slowly if at all if it depends on a single individual. The smaller the population, the higher the probability that the adaptation will be eliminated by chance.

Column A: Label the organism as a producer, an herbivore, a carnivore, a scavenger, or a decomposer. Column B: Find an image of
Effectus [21]

<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.
