What's the difference between a producer and a consumer? Where do producers belong in a food chain?

Producers are at the bottom or beginning of the food chain because they produce their own food. producers do not eat other organisms unless there are exceptions. consumers eat other consumers and also eat producers.

The half-life carbon-14 is 5730 years. Archaeologists dig up a seed that contains 0.25 parts per trillion of carbon-14. If it or

Answer:

A)11,460 years

Explanation:half of a radioactive element represent the time take for half of it's components to dissociate or disintegrate.

For carbonn14 that undergo an emmision to form a stable carbon 14,it moves thus

14C(1 part) ______14C(0.5 parts)_____14C(0.25parts)

i.e it undergo two radioactive decay which means two half lives .

Since each half life is 5780 years ,the age will be 2×half lives= 2×5780=11,460 years

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! :-)
