why are there more producers than primary consumers and primary consumers than higher order consumers?

1 answer:

6 0

This is because the level of energy decreases throughout the food pyramid.

At the beginning with producers, they contain the most energy or 100%. However, once they are consumed, the consumer loses 90% of the energy. Thus, primary consumers only get 10% of the energy, secondary consumers only get 1% and so on and so forth higher.

Because of the lack of energy being passed along within the food pyramid, higher order consumers (typically carnivores) must have a lot of prey to consume, but this also means competition. Therefore, higher in the ranks, there is more competition which leads to smaller populations.

Hope this helps!

Svetlanka [38]

Answer:

Explanation:

mRNA (messanger ribonucleic acid) is produced through the process called transcription in the nucleus. Transcription make ribonucleic acid from deoxyribonucleic acid. The enzyme RNA polymerase creates an RNA molecule that is complementary to the template DNA coping all the information on the DNA into the mRNA formed and 3' to 5' cap are added to stabilize the RNA after which this mRNA then moves from the nucleus where it was produced to the ribosome in the cytoplasm for translation of the information that is coded in the bases.

FGF5 is a gene that is encoded in the DNA.

The graph pictured shows bacterial growth, in a petri dish, in which no additional resources are added over time, The graph pictured shows bacterial growth, in a petri dish, in which no additional resources are added over time.

<h3>How does the bacteria actually grow in the petri dish?</h3>

Sterile powdered agar with nutrients can be mixed with moisture, heated and then rushed into empty petri plates or ready-to-use dishes can be purchased.

The undigestible agar is a gelatin-like substance with a semi solid surface on which the bacteria can grow while they engulf the added nutrients

Thus, option "D" is correct.
