Analyze the pyramid representing the energy flow through an ecosystem. Select the phrases that accurately describe the flow of e
saveliy_v [14]

In a typical energy pyramid, herbivores have more energy available to them than carnivores, tertiary consumers are fewer than secondary consumers, and soil organisms recycle nutrients.

<h3>Energy pyramid in the ecosystem</h3>

The producer forms the bases of the energy pyramid of any ecosystem. this is followed by the primary consumers, secondary consumers, tertiary consumers, and quaternary consumers respectively.

The population at each trophic level decreases as we move up, resulting in a form of a pyramid. Also, the amount of energy obtained at each trophic level decreases as we move upward.

Thus, one can effectively conclude that:

  • Herbivores have more energy available to them than carnivores.
  • There are fewer tertiary consumers than secondary consumers.
  • Soil organisms recycle nutrients but not energy back into the ecosystem.

How are proteins made in animals and humans
ehidna [41]

Answer:

Through protein synthesis of course...

Explanation:

DNA and RNA do many steps such as translation, transcription, and more to form protein codons and code them into amino acids. Then, thousands of amino acids are oined together to make proteins, which regulate body function and catalyze chemical reactions (enzymes). Ribosomes are also involved in this action. To make proteins, nitrogen is needed for the plant to use, and that comes mainly from nitrate ions in the soil, and gets into the plant by active transport.
