## What is population dynamic growth?

Definition. Population dynamics is the study of how and why populations change in size and structure over time. Important factors in population dynamics include rates of reproduction, death and migration.

## What is fluctuating growth in biology?

In population ecology: Population fluctuation. As stated above, populations rarely grow smoothly up to the carrying capacity and then remain there. Instead, fluctuations in population numbers, abundance, or density from one time step to the next are the norm.

**What is population dynamics biology?**

Population dynamics is the portion of ecology that deals with the variation in time and space of population size and density for one or more species (Begon et al. 1990).

### What are the two types of growth biology?

The equation above is very general, and we can make more specific forms of it to describe two different kinds of growth models: exponential and logistic. When the per capita rate of increase ( r) takes the same positive value regardless of the population size, then we get exponential growth.

### What is an example of a dynamic population?

If we are interested in a question that is only relevant while the person lives in Boston, such as risk of accidents while riding a bicycle, then the population is dynamic, because once a person moves out of Boston there is no reason to follow them.

**What is the example of population dynamic?**

The term “population dynamics” refers to how the number of individuals in a population changes over time. Biologists study the factors that affect population dynamics because they are interested in topics such as conservation of endangered species (for example, the Florida panther) and management of fish and wildlife.

## What are the types of population dynamics?

Biologists distinguish between two main types of populations: unstructured and structured. In an unstructured population, all individuals are subject to the same general ecological pressures. That is, the rates of growth, reproduction, and mortality are roughly the same for all individuals in the population.
