The definition of population dynamics.
Introduction:
Ecology is the study of the different aspects of the environment. There are mainly two types of environment − physical and socio-cultural. The living organisms inhabit the physical environment. Population refers to the total number of a particular species of living organisms present in a habitat of an environment.
Population dynamics − It is a study of the various aspects of the population of the species of different living organisms. It involves the analytical study of the changes in population over time and the reasons behind the changes.
Therefore, population dynamics are associated with the study of various species inhabiting a particular population group as well as the reasons behind the changes in population with time.

The definition of total fertility rate.
Introduction:
Ecology is the study of the different aspects of the environment. There are mainly two types of environment − physical and socio-cultural. The living organisms inhabit the physical environment. Population refers to the total number of a particular species of living organisms present in a habitat of an environment.
Total fertility rate − This is defined as the summation of the fertility rates of the women population across the various age groups. The sum-total of the fertility rates is then multiplied by 5.
Therefore, the total fertility rate is the sum of the fertility rates of the women inhabiting a specific population group.

The definition of environmental health.
Introduction:
Ecology is the study of the different aspects of the environment. There are mainly two types of environment − physical and socio-cultural. The living organisms inhabit the physical environment. Population refers to the total number of a particular species of living organisms present in a habitat of an environment.
Environmental health − This is the study of the impact of the environment on the health of individuals or communities. This involves analysis of the effects of both physical and social environment on the various aspects of human health.
Therefore, environmental health is the study of the impact of the environment on the health of individuals or communities.

The definition of environmental risk transition.
Introduction:
Ecology is the study of the different aspects of the environment. there are mainly two types of environment − physical and socio-cultural. The living organisms inhabit the physical environment. Population refers to the total number of a particular species of living organisms present in a habitat of an environment.
Environmental risk transition − This involves the change in the diseases or illnesses that can induce risk due to advancements in the conditions of the traditional communities.
Physical and social environment − Physical environment comprises the natural habitat where an individual lives. The social environment consists of the social groups or communities that are needed for human settlement and interactions.
Therefore, environmental risk transition involves the change in the diseases or illnesses that can induce risk due to advancements in the conditions of the traditional communities.

To write:
The definition of demographic transition.
Introduction:
Ecology is the study of the different aspects of the environment. there are mainly two types of environment − physical and socio-cultural. The living organisms inhabit the physical environment. Population refers to the total number of a particular species of living organisms present in a habitat of an environment.
Demographic transition − Transition means change. Demographic transition means changes in the population count, specifically from high birth and death count to low birth and death count due to advancements in technology.
Therefore, demographic transition means changes in the population count, specifically an increase in the population count due to technological advancement.

The definition of epidemiologic transition.
Introduction:
Ecology is the study of the different aspects of the environment. there are mainly two types of environment − physical and socio-cultural. The living organisms inhabit the physical environment. Population refers to the total number of a particular species of living organisms present in a habitat of an environment.
Epidemiologic transition − This involves the change in mortality, morbidity, and life
expectancy rates of a given population over time.
Therefore, the epidemiologic transition is associated with the change in the mortality, and morbidity of a given population over time.
