An organism of the same species in a location is called a population.
The field of ecology that deals with studying population and its association with the environment is called Population Ecology.

A group of organisms of the same species that live in a specific location
A group of organisms of the same species that live in a specific location is a population.
For example, palm trees on an island, a group of gazelles, monarch butterflies in Central Mexico, or the number of people living in New York City are populations of specific species.
More than one population of species can live in one area. For example, a population of Black Scorpion and a Saguaro Cacti can be found in a desert habitat.
A group of organisms of the same species that live in an area
A group of organisms of the same species that live in an area is a population. A population can be grouped according to geographical boundaries. Some populations remain within their specific limits whereas others don’t.
These groups include:
- Local Population:
- A group of organisms of the same species that live in a particular area
- They prefer isolation from other populations and are self-sustainable
- They extinct within a precise time frame
- Metapopulation:
- Grouping of local populations living in a suitable habitat
- Spatially-structured population:
- A population whose survival rate depends upon biological and environmental relationships group of individuals that belong to the same species and live in the same area
A group of individuals that belong to the same species and live in the same area
A group of individuals that belong to the same species and live in the same area can compete for survival.
Individuals that are well adapted to the environment survive. It is termed “survival of the fittest,” The process is called Natural Selection. For example, individuals who are better at finding food or shelter resources will survive longer than others.
A group of the same species living the same environment is called a
A group of the same species living in the same environment is called a population. Population Ecology is the specialized field for studying a group of the same species living in the same environment and interacting with the surroundings. The study includes environmental impact on its size and structure and the number of species that live in an area.
A few characteristics of population ecology are:
- Population Density:
- Number of individuals living in a specific area
- Low-Density areas will have scattered individuals, and high-density areas will have a complete number of individuals with high competition.
- Measured as the number of individuals per unit area
- For example, 4 million diatoms per cubic meter of water
- Population Size:
- Total number of individuals in a population and represented by “N” in studies
- Population Dispersion:
- The distribution of individuals in an area and how they interact.
- It is within a geographical boundary and is measured through pattern spacing.
For example, the study of Population ecology can initiate the practice of growing breeding and caring for plants to increase specific kinds of plants or trees.
All members of a species living in the same area
All members of a species living in the same area is a population. The study of how population change refers to Population Dynamics.
Population Dynamics help scientists to understand the following:
- Reasons for population fluctuation
- Reasons for an abundance of population in an area
- Conservation management
- Biological resource management
Factors affecting population dynamics include:
Population Density:
Done through counting the number of individuals in an area
It gives an approximation of the total number of individuals in a habitat
Birth Rate:
Number of individuals born in a population in a respective time frame
Death Rate:
Number of death of individuals in a population in a respective time frame
All members of a species that live in the same area at the same time make up a
All members of a species that live in the same area at the same time make up a population. Scientists divide populations into the following:
Unstructured Population:
- All individuals of species face the same ecological pressure
- It includes birth rate, growth rate, and death rate and is the same for all individuals
- For example, a bacterial colony
Structured Population:
- Individuals face different ecological pressures.
- In this way, some individuals are more vulnerable to surviving or dying.
- For example, in populations of sea turtles or trees which death rate of young individuals is more as compared to adults
All populations of all species living in the same area
Community is defined as all populations of all species living in the same area.
In a community, organisms share a common habitat.
Examples of the community include a pond or a forest, where all populations of all species share a common land.
Communities evolve to have greater biomass and species richness in a process called succession.
A biological community and its associated physical environment comprise an ecosystem
Several different species make up a
Several different species make up a community. All species, including animals and plants living together with mutual benefit in an area, is called a Biotic community or Biological community.
Characteristics of the biological community include:
- Diversity:
The community comprises multiple plants, animals, and microorganisms. These populations are different from each other and hence show diversity.
- Growth Forms:
Each community has groups of growth structures, including herbs, shrubs, mosses, small plants, and trees. These groups are called growth forms. They help to study the zonation of a community.
- Dominant species:
Few populations in a community have control over weaker populations due to numbers, size, or behavior. They are known as the dominant species.
- Trophic structure:
A tier-based structure in which each tier represents food source and function. Interdependence in nature is illustrated by the transfer of energy through trophic levels.
Which of the following terms or structures is properly associated only with animals?
The term or structure properly associated only with animals is Hox Genes. They play a vital role in embryonic development for all animals. They determine head-tail axis and body plan in a developing embryo in animals only.
Which of these terms refers to a group of populations living in a given area?
The term that refers to a group of populations living in a given area is a community. All populations of all populations of diverse species live together in a community. A community differs from a population in that a community includes interaction among group of varying species.
FAQ
What is a group of the same kind of organisms that live in the same area at the same time?
A group of the same kind of organisms that live in the same area at the same time is a population. In addition, the different populations of all the species in a given area make up a community
What term is defined as a group of organisms of the same species interacting in a given area?
The term defined as a group of organisms of the same species interacting in a given area is a population. For example, the number of stray dogs in a city and the number of coniferous trees in a specific area.
What is an association of individuals of the same species living in the same area?
An association of individuals of the same species living in the same area is a population. Ecological population definition describes it as a group of creatures belonging from the same species group, that exist in the same time and same confined space.
