Which best describes the process that the pest population has experienced due to this environment change?

Genetic Resistance

Explanation:The use of insecticides as such does not create resistance but it can develop through the overuse or misuse of an insecticide against a pest species. Resistance develops when naturally occurring genetic variation allows a small proportion of the population to resist and survive the effects of the insecticide.

1: most common garden plants prefer loam — soils with a balance of different-sized mineral particles (approximately 40% sand, 40% silt, and 20% clay) with ample organic matter and pore space. however, some plants grow better in sandy soils, while others are well-adapted to clay soils.

2: available water capacity is the maximum amount of plant available water a soil can provide. it is an indicator of a soil's ability to retain water and make it sufficiently available for plant use. available water capacity is the water held in soil between its field capacity and permanent wilting point.

3: it is the same for all living things (plants and animals). it also includes very tiny organisms that our eyes cannot see. they are known as microorganisms, and include viruses, bacteria and fungi.
