During cellular respiration what is the direct source of the energu used in the cells of consumers?
nexus9112 [7]

Answer:

Consumers use chemical energy from the chemical bonds within organic molecules such as carbohydrates, lipids,  and amino acids.

Explanation:

<u>Heterotrophs are consumers</u>; they ingest or absorb organic matter (lipids, carbohydrates, proteins, etc.)  made by autotrophs or producers for their energy consumption. Autotrophs include plants, bacteria, and other photosynthesizing organisms, while heterotrophs include animals, fungi, protists, and bacteria.

Heterotrophs obtain energy from food through the process of cellular respiration. For instance, during aerobic respiration in mitochondria, they break down sugars in the form of glucose into carbon dioxide and water to obtain energy in the form of ATP or adenosine triphosphate.

aerobic respiration:      C6H12O6+ 6 O2 → 6 CO2 + 6 H2O + ≅38 ATP

                                      glucose+ oxygen →  carbon dioxide+ water+ energy

Why can't prokaryotic species be defined as a group of similar organisms that could sexually reproduce together?
s344n2d4d5 [400]

Answer:

The prokaryote divides by asexual mode of reproduction.

Explanation:

The concept of species which defines a species as a group of individuals of a population which can interbred and produce a fertile progeny is applicable to the organism which can reproduce sexually.

Since the bacteria divide through asexual means and not through sexual ways therefore the concept of defining a species becomes complicated and does not apply.However the concept of species in prokaryotes is still a topic of research.  

Thus, the biological concept of species is not applicable to prokaryotes.

Vlad [161]

Answer:

  1. <u>The hours are the independent variable.</u>
  2. <u>The wages/wk earned are ( $11/hr )x( hrs worked ) . This is the dependent variable ( depends on hours worked ) .</u>
  3. <u>The domain is 0 to 30 </u>
  4. <u>The range is 0 to 330 </u>

Explanation:

<em>The hours are the independent variable and  should be plotted on the x-axis .</em>

<em>The wages/wk earned are ( $11/hr )x( hrs worked ) . This is the dependent variable ( depends on hours worked )  and should be plotted on the y-axis </em>

<em>--------------- </em>

<em>Let +W+ = wages/wk earned </em>

<em></em>

<em>Let +h+ = hours/wk worked </em>

<em>The equation is: </em>

<em>+W+=+11h+ </em>

<em>The domain is 0 to 30 </em>

<em>( no hrs worked to 30 hrs worked ) </em>

<em>The range is 0 to 330 </em>

<em>( no wages eared to +11%2A30+=+330+ earned )</em>
