An energy pyramid shows how energy flows through an ecosystem. An image is provided. Each level gets only about 10% of the energy from the previous level. If living systems follow the law of conservation of energy, where does the remaining 90% of the energy go?
A. A It is used by decomposers during decomposition.
B. B It is converted into heat and energy for life functions.
C. C It is converted to matter during digestion.
D. D It is used by organisms in the lower trophic level.
Answers
Answer:
b
Explanation:
some is used, some is wasted by giving off heat, being excreted, etc
The statement (B) is correct. It is converted into heat and energy for life functions.
What is an ecosystem?An ecological pyramid is a graphical representation designed to show the biomass or bioproductivity at each trophic level in a given ecosystem.
Moreover, an energy pyramid is a model that shows the flow of energy from one trophic, or feeding, level to the next in an ecosystem. The model is a diagram that compares the energy used by organisms at each trophic level. The energy in an energy pyramid is measured in units of kilocalories (kcal).
Therefore, a pyramid of energy represents how much energy, initially from the sun, is retained or stored in the form of new biomass at each trophic level in an ecosystem. Typically, about 10% of the energy is transferred from one trophic level to the next, thus preventing a large number of trophic levels.

When both the P and A site are occupied and a third tRNA anticodon comes to the ribosome, what happens to the first anticodon?
Answers
Answer:
The first anticodon leaves the ribosome through the E-site
Explanation:
Translation is the second stage of gene expression. It occurs in the ribosomes (organnelles of protein synthesis) where amino acid sequence is synthesized using a mRNA template. The tRNA (transfer RNA) is responsible for reading the mRNA codon using its ANTICODON, which is complementary to the mRNA codon.
The tRNA reads the mRNA codon and carries the amino acid that corresponds what it reads. tRNA has three binding sites on the ribosome; A-site, P-site and E-site. A tRNA molecule with the complementary anticodon binds to the codon on the P-site, and carries its corresponding amino acid. Another tRNA with complementary anticodon occupies the A-site, carrying the corresponding amino acid again.
Once both sites are occupied, the tRNA on the P-site transfers its amino acid to the one on the A-site to form a peptide bond. This causes the ribosome to shift the tRNA on the P-site, allowing the one on the A-site to be free. When this happens, the anticodon of the first tRNA on the P-site leaves the ribosome via the E-site in order to bind to another complementary mRNA codon and continue the translation process.

Why is West Ferris not running out of water
Answers
Answer:
The population of East Ferris is increasing over time, while the amount of rainfall in East Ferris stays about the same over time. ... The population of East Ferris remains the same over time, while the amount of rainfall in East Ferris increases over time.
Explanation:
West Ferris is not running out of water as it rains more in West Ferris than in East Ferris.
• In the East Ferris, the population is increasing with time, while the amount of rainfall in East Ferris remains similar with time.
• Over the West Ferris the water vapor gets high up in comparison to the East Ferris. This makes water vapors to move to distinct parts of the atmosphere, and the mountains and winds direct the water vapors to the West Ferris.
• Due to the rain shadow effect, it rains more on the West Ferris. The sides of the mountains, which are hit more by wind exhibits more precipitation in comparison to the sides, which are not, this is known as the rain shadow effect.
• The wind seems to move from East to West, with the upward movement of the humid air, it gets cool and the condensation of water vapors takes place into clouds and falling of rain takes place.
Thus, due to continuous rain in the West Ferris it does not run out of water.
