The producers had 6,000 kcal of energy , how much would be passed to the primary consumer?
morpeh [17]

Answer:

600 kcal

Explanation:

In an ecosystem, energy is transferred from one organism in a trophic level to another organism in another trophic level. Organisms called PRODUCERS are capable of deriving energy from the sun. However, when fed upon by PRIMARY CONSUMERS, only about 10% of the energy is transferred to them because most of the energy (90%) is lost as heat.

Hence, in this case where the producers had 6,000 kcal of energy, 10% i.e. 10/100 of 6000 = 600 kcal of energy will be transferred to the primary consumers.

4.4-1 Anaerobic Respiration
Vesna [10]

For lactic acid fermentation, the correct options are:

  • pyruvate
  • hydrogen
  • NADH
  • lactic acid
  • Lactic acid
  • pyruvate
  • mitochondria

For ethanol fermentation, the correct options are:

  • pyruvate
  • CO₂
  • acetyl CoA
  • acetyl CoA
  • acetaldehyde
  • Acetaldehyde
  • hydrogen
  • NADH
  • ethanol

<h3>What is a anaerobic respiration?</h3>

Anaerobic respiration is respiration which occurs in the absence of oxygen.

Oxygen is used as an electron acceptor during respiration. However, when oxygen is absent or insufficient, other molecules are used as electron acceptors in order to produce energy.

Anaerobic respiration in large organisms may result in the formation of lactate known as lactic acid fermentation.

In lactic acid fermentation, after glycolysis, the two pyruvate molecules receive hydrogen atoms from NADH creating lactic acid. Lactic acid can be converted back into pyruvate in the liver. The pyruvate can then enter into the mitochondria and cellular respiration, can proceed.

On the other hand, anaerobic respiration in microorganisms produce ethanol and is known as ethanol fermentation.

After glycolysis, the two pyruvate molecules lose a CO₂ atom, creating acetyl CoA. The acetyl CoA atom combines with hydrogen to form acetaldehyde. Acetaldehyde receives a hydrogen atom from NADH, resulting in the production of ethanol.

In conclusion, anaerobic respiration can occur either as a lactate fermentation or ethanol fermentation.
