Answer

Answer:

  • The number of producers is greater than the number of primary consumers.
  • The amount of energy at the primary consumer level is greater than the amount of energy at the secondary consumer level.

Explanation:

Step1: Understand energy - pyramid concept

In an energy pyramid, energy and biomass decrease as we move up the trophic levels.

Step2: Analyze producer - primary consumer relationship

Producers form the base of the pyramid. There are more producers to support a smaller number of primary consumers, so the number of producers is greater than the number of primary consumers.

Step3: Analyze energy transfer between levels

Energy is lost as heat and for metabolic processes at each trophic level. So, the amount of energy at the primary consumer level is greater than that at the secondary consumer level as only about 10 - 20% of energy is transferred from one level to the next.

Step4: Analyze primary - secondary consumer number relationship

There are more primary consumers than secondary consumers as there is more available energy at the primary - consumer level to support a larger population, so the statement "The number of primary consumers is less than the number of secondary consumers" is false.

Step5: Analyze producer - primary consumer energy relationship

Producers capture energy from the sun and have the most energy in the ecosystem. The amount of energy at the producer level is greater than at the primary - consumer level, so the statement "The amount of energy at the producer level is less than the amount of energy at the primary consumer level" is false.
