Which of the following situations accurately describes a difference between a food chain and a food web? Select one:
Natasha2012 [34]
Lets look at your first question. A food chain is a linear (line) relationship between organisms. It shows who eats what and who gets eaten. The energy is passed up the chain from one organisms to the next. A food web is a series of interconnected food chains. It can show one organism being preyed upon by several predators. The answer choice A is really referring to an energy pyramid, but it is true in any ecosystem that only 10% of available energy is passed to the next trophic level. B and C are both true statements as well. D is completely false because 90% of energy is lost, not retained. So with that said, there is more than one correct answer here. I have included a diagram so you can see the difference between the two. 

For Question 8, the key to understanding this is that sunlight is the main source of energy for any ecosystem. Plants (autotrophs) use the sunlight to convert it to sugars (glucose) which is a compound that heterotrophs can utilize. This process is called photosynthesis. :-) 

Question 9: So in a food chain, you typically start with the producers (plants), then to the primary consumer, then secondary consumer, then tertiary consumer, and in some cases you may have a quaternary consumer. That is 4 links. However, we are forgetting the role of decomposers at all levels of this food chain, and that would add an extra link. In summary, you wouldn't typically see more than 5 links in a food chain. 

I hope all of my explanations are helpful! Good luck! :-)

3. Why is it easy to describe an organism's phenotype for a particular characteristic but
JulsSmile [24]

Answer:

The sum of an organism's observable characteristics is their phenotype. A key difference between phenotype and genotype is that, whilst genotype is inherited from an organism's parents, the phenotype is not. Whilst a phenotype is influenced the genotype, genotype does not equal phenotype

Can someone please help me
Usimov [2.4K]

Answer:

1A - Respiratory = trachea, lungs... however both arteries and veins move oxygen around the body, and are therefore valid answers

1B - Skeletal = bones

1C - Muscular = muscles

1D - Digestive = stomach, large/small intestine

1E - Circulatory = heart, veins and arteries

2. Cellular respiration is the conversion of sugar into energy the cell uses to function via various chemical reactions. Digestion is an example of this. Stomach acid breaks down food into sugars that cells break down further into energy to keep you alive

3. Bones contain bone marrow deep inside of them which is responsible for the creation of red blood cells. Your lungs can move air all they want but would be useless without red blood cells to take the oxygen to cells and take the CO2 away from them.

The large surface area in the gut directly facilitates _____.
Flura [38]

Answer:

B. Absorption

Explanation:

  • Absorption is a process that takes place in the small intestines or ileum of the GI tract, in which simple and soluble nutrients are absorbed into the blood stream.
  • Absorption is enhanced by several adaptations of the gut such as large surface area of the gut which directly facilitates absorption of nutrients.
  • Presence of villi and microvilli in the gut increases the surface area for absorption of nutrients in the ileum.
