Answer:

It is true that studying natural selection in the fields can be challenging. Some of the challenges which Darwin might have faced could have been:

Darwin was only studying one trait for his results. But there might have been many other factors or traits affecting natural selection.

Natural selection does not happen rapidly hence Darwin would have had to wait for many generations to observe the results.

The environment is not such an easy factor to study. It is complex. It might have happened that the environment might have changed before any changes were seen in the population of the birds.

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.
