Answer:
Ecology is defined as the scientific study of the complex interactions between organisms, and the environment of the earth. Ecologists study, and examine the features of biotic and abiotic factors of the environment.
Abiotic factors include non-living factors, the physical, and chemical attributes, for example light, water, temperature, and nutrients which helps to influence the abundance, and distribution of organisms.
Biotic factors include living factors, the other organisms which are part of a separate environment, similarly influence the abundance and distribution of life present on Earth.

The adaptive immune response is the second line of defense against non-self pathogens. Adaptive immunity, also known as acquired immunity or specific immunity, is found only in vertebrates.
<h3>What is second line of defense?</h3>
Nonspecific resistance, which destroys invaders without targeting specific individuals, is the second line of defense: phagocytic cells ingest and destroy all microbes that enter body tissues.
The adaptive immune response is the body's second line of defense against non-self pathogens. Adaptive immunity, also known as acquired immunity or specific immunity, is found only in vertebrates.
Thus, adaptive immune system is a natural, nonspecific immune response, but it is part of the body's second line of defense.
