Whatever is being produced, you want to know everything that was made, whether or not you end with it. Like in fermentation. Say you make 4 atp, but use 2 in the process, you end with a net gain of 2, but overall made 4.

In 3–5 sentences, compare and contrast the flow of matter and energy in each trophic level for land-based ecosystems and marine
Mnenie [13.5K]

Answer:

Unlike matter, as energy flows through an ecosystem in one direction, from photosynthetic organisms to herbivores to omnivores and carnivores and decomposers, less and less energy becomes available to support life.

Explanation:

Primary producers use energy from the sun to produce their own food in the form of glucose, and then primary producers are eaten by primary consumers who are in turn eaten by secondary consumers, and so on, so that energy flows from one trophic level, or level of the food chain, to the next.

Energy is acquired by living things in three ways: photosynthesis, chemosynthesis, and the consumption and digestion of other living or previously-living organisms by heterotrophs.

Living organisms would not be able to assemble macromolecules (proteins, lipids, nucleic acids, and complex carbohydrates) from their monomeric subunits without a constant energy input.

The half — life of nickel is 96 years. How much of a 30-gram sample is left after 270 years?
-Dominant- [34]

The amount of the 30 gram-sample that will remain after 270 years is 6.61 grams

<h3>How to determine the number of half-lives </h3>

We'll begin by obtaining the number of half lives that has elapsed. This can be obtained as follow:

  • Half-life (t½) = 96 years
  • Time (t) = 270 years
  • Number of half-lives (n) =?

n = t / t½

n = 270 / 99

n = 2.8125

<h3>How to determine the amount remaining </h3>
  • Original amount (N₀) = 30 grams
  • Number of half-lives (n) = 2.8125
  • Amount remaining (N) =?

The amount remaing can be obtained as follow:

N = N₀ / 2^n

N = 30 / 2^2.8125

N = 6.61 grams
