Some areas of a forest contain rich soil, while in other areas the soil is poor. Plants of a certain species grow taller in the

rich soil than in the poor soil. The taller plants receive more sunlight and are able to produce more offspring than the shorter plants. If these offspring grow in rich soil, they are tall, but if they grow in poor soil, they are short.Which of the following statements best explains why this situation is not an example of evolution by natural selection?
A The observed differences in plant height are not due to genetics.
B The differences in soil conditions do not affect all plants equally.
C The short plants and tall plants are not isolated enough from each other.
D The short plants are not accumulating gene mutations as quickly as the tall plants.

Answer:

A. The observed differences in plant height are not due to genetics.

Explanation:

In this case, the height of the plants is not related to the genetics of these organisms, but due to the influence of soils rich in nutrients and a higher incidence of sun on them.

The sun stimulates the growth of plants, plants that are shaded are shaded, their growth is impaired, they cannot reach the growth determined by their genetics, being lower than the trees that are receiving sun. Some plants do not grow at all without the sun and end up dying.

In addition, plants need nutrients to grow. When the soil is rich in nutrients, the plant is able to absorb them in quantities necessary for their development and ends up growing more than plants that are in poor nutrient soils.
