What is logistic growth?
Population growth in which the growth rate decreases with increasing number of individuals until it becomes zero when the population reaches a maximum.
The rate at which a population of a given species will increase when no limits are placed on its rate of growth?
The rate at which a population will increase with no limits is called its intrinsic growth rate. This rate is influenced by factors such as birth rate and death rate within the population. It represents the maximum potential for growth in ideal conditions.
What is absolute growth rate?
Absolute growth rate(agr) curve enables us to express the growth of organisms in terms f growth rate. In most organism, agr increases steadily until reaches a maximum and then, gradually falls. Agr is a bell-shaped curve.
How is a growth rate related to a growth factor?
A growth factor is a numerical value that quantifies the increase or decrease of a quantity over time, while a growth rate is the percentage change in that quantity over a specific period. The growth factor is derived from the growth rate by adding 1 to the growth rate percentage expressed as a decimal. For example, a growth rate of 5% corresponds to a growth factor of 1.05.

Why and in which phase specific growth rate are measured in microbial culture?
In fermentation process specific growth rate measurement become necessary. The growth rate is studied after every half hour in case of experiment and optical density is checked.depending upon which phase of culture is determined.But usually log phase is preferred to check specific growth rate. Because, mainly industrial processes are carried out at continuous fermentation where it become necessary to maintain the growth rate. The depletion of growth requires addition of some inoculum i e culture using chemostat
The maximum rate of increase of a population is its?
The maximum rate of increase of a population is its biotic potential, which represents the highest possible growth rate under ideal conditions, unaffected by environmental factors such as resource availability or competition.
How would you determine the growth rate of a lichen?
To determine the growth rate of a lichen, you can measure the increase in size or area over a specific period of time. Marking the boundaries of the lichen and monitoring its expansion can help estimate its growth rate. Additionally, counting the number of new branches or lobes can also provide insight into its growth rate.
What are the three ways that a growth rate may be started or expressed?
Percentage growth rate: expressed as a percentage change in value over a specific time period. Compound annual growth rate (CAGR): a geometric progression rate that provides a constant growth rate. Absolute growth rate: expressed as a simple difference in values between two time periods.
What is intrinsic growth rate?
The intrinsic growth rate of a population is the maximal rate at which the populatiom would grow under ideal conditions (i.e., unlimited resources, no competition, no predation, and no envionmental stress). In all real situations however, the population growth rate is kept in check by extrinsic factors.
What is specific growth rate constant?
The specific growth rate constant, often denoted as μ, is a measure of how fast a population of microorganisms grows exponentially under ideal conditions. It is used to quantify the rate of cell growth or biomass production in biological systems. The specific growth rate constant is an important parameter in microbiology, biotechnology, and other fields related to cell or microbial growth.
What is cgr in plants?
CGR in plants refers to the "crop growth rate," which is a measure of how quickly a plant is growing during a specific time period. It is often used by researchers to assess and analyze the growth and development of crops in agriculture. By monitoring the crop growth rate, farmers can make informed decisions about management practices and optimize crop yield.
