As we burn fossil fuels, which are carbon containing compounds, for fuel, we increase atmospheric carbon dioxide at a rate faster than carbon-fixing components of the cycle, like plants, can use it, leading to increased carbon dioxide.

ivolga24 [154]
Well, you don't specify the parent traits, so I'll just do one for each...

If both parents are homozygous RR, then all 60 of the babies will be black

If both parents are homozygous WW, then all 60 of the babies will be white 

If both parents are heterozygous RW, then there will be 15 black babies, 15 white babies, and 30 spotted babies. 

If one parent is homozygous RR and one is homozygous WW, then all of the babies will be spotted

If one parent is homozygous RR and one is heterozygous RW, then 30 of the babies will be black, and 30 will be spotted

If one parent is homozygous WW and one is heterozygous RW, then 30 of the babies will be white, and 30 will be spotted.

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.

aev [14]

Decreased birthrate always affects the numbers in terms of population.The less births there are, the smaller the number of people. Even if the death rate remains constant a decreased birthrate will slow growth of population.
