Determine if the following statement is true or false and why. “Primary and Secondary Consumers lose about 30% of the energy the
Elodia [21]

True. The correct option is C.

<h3>Energy transfer in the ecosystem</h3>

Energy is transferred from lower to higher trophic levels of the food chain in any ecosystem.

In other words, energy is transferred when primary consumers feed on producers, when secondary consumers feed on primary consumers, and so on.

However, when energy is transferred through feeding from lower to higher trophic levels, a certain percentage of the energy is lost to the surroundings as heat.

In actual fact, scientists believe that about 90% (and not 30%) of the energy is lost as heat to the surrounding. Only about 10% of the energy is converted to useful energy.

Because their structures are different, both are proteins but are shaped in space differently, causing hemoglobin to saturate at high partial pressures of oxygen, and yield oxygen to the medium, while myoglobin at high partial pressures of oxygen will taking.

Explanation:

Hemoglobin has a tetrahedral form, while myoglobin contains a triad form of three main components and not 4.

In addition, myoglobin must capture oxygen to oxygenate the muscle in muscle contraction, since this demands the presence of this gas and the energy currency that is called ATP.
