The correct answer is B. The base of the pyramid generally represents primary consumers.

Explanation

A biomass pyramid is a graphic representation of the biomass present in a unit area of various trophic levels, this graphic representation shows the relationship between biomass and the trophic level that quantifies the biomass available at each trophic level of an energy community at a specific time. In general, an ecosystem is represented in a pyramid in which the primary producers occupy the base of the pyramid because they have more biomass in a unitary area. An example of the organization of a biomass pyramid is an ecosystem in which caterpillars feed on oak trees; In turn, the caterpillars are consumed by a bluebird, which is consumed by a sparrowhawk. In this example, the oak tree is at the base of the biomass pyramid, because it feeds dozens of caterpillars, thanks to its massive biomass, and the sparrowhawk occupies the highest level of the pyramid. Therefore, it is incorrect to affirm that the base of the pyramid generally represents primary consumers, because the primary producers are generally at the base of the pyramid. So, the correct answer is B. The base of the pyramid generally represents primary consumers.

Answer: The answer is option B

Explanation:

The base of the pyramid represents primary producers since they help to pass on energy to consumers as we go higher in the pyramid. They are not consumers because they supply energy and do not use up energy. They are called autotrophs.

saveliy_v [14]

Answer:

b. able to travel through a vacuum.

Explanation:

The most distinguishing factor of an electromagnetic waves is that they are able to travel through a vacuum.

These waves do not require materials in a medium for propagation.

  • Electromagnetic waves are formed by the propagation of the electric and magnetic fields.
  • They vibrate at an angle of 90° .
  • They are unlike like mechanical waves that requires that requires materials in medium for their propagation.
