In ecology, a community is a group or association of populations of two or more different species occupying the same geographical area at the same time, also known as a biocoenosis, biotic community, biological community, ecological community, or life assemblage.

What does a biological community consist of quizlet?

A biological community is in assemblage of all the population of organisms living close enough together for potential interaction.

What are the types of biological community?

  • Minor Community.
  • Trophic Organization.
  • Dominance.
  • Interdependence.
  • Community Structure.

What are the characteristics of biological community?

Solution : Organisms are not uniformly distributed throughout a community. They usually occur in populations is called stratification which is characteristic of biological community. Natality, mortality, age structure and sex-ratio are the basic characteristics of a population.

What are populations in biology?

A population is a subset of individuals of one species that occupies a particular geographic area and, in sexually reproducing species, interbreeds. The geographic boundaries of a population are easy to establish for some species but more difficult for others.

What is an example of a population in biology?

Population Definition The term “population” encompasses a group of organisms of a single species that can interbreed and live in the same time in the same environment. For example, a “population” of deer includes all individuals in a particular forest.

What is a species in biology quizlet?

Definition. 1. A species are organisms that can interbreed with each other & produce fertile offspring (old definition). 2. A class of individuals having some common characteristics or qualities; distinct sort or kind.

What is biosphere short answer?

The biosphere is made up of the parts of Earth where life exists. The biosphere extends from the deepest root systems of trees, to the dark environment of ocean trenches, to lush rainforests and high mountaintops. Scientists describe Earth in terms of spheres. The solid surface layer of Earth is the lithosphere.

What makes up the biosphere quizlet?

The biosphere is composed of all living organisms. Plants, animals, and one-celled organisms are all part of the biosphere.

What is another name for the biosphere?

The biosphere (from Greek βίος bíos “life” and σφαῖρα sphaira “sphere”), also known as the ecosphere (from Greek οἶκος oîkos “environment” and σφαῖρα), is the worldwide sum of all ecosystems. It can also be termed the zone of life on Earth.

How does a biological community develop?

community ecology, study of the organization and functioning of communities, which are assemblages of interacting populations of the species living within a particular area or habitat. As populations of species interact with one another, they form biological communities.

What is an ecosystem biological community?

An ecosystem is a complete community of interdependent organisms as well as the inorganic components of their environment; by contrast, a biological community is just the living members of an ecosystem.

What are the factors that make up a community?

  • Shared identity. It is common for communities to form among those who share a common sense of identity.
  • Shared purpose. Those who feel passionately about social causes will often band together as a community.
  • Common objectives.
  • Shared interests or passions.
  • Common Behavior.

What are the 4 types of population?

  • Finite Population.
  • Infinite Population.
  • Existent Population.
  • Hypothetical Population.

How is a population composed?

Population composition is the description of the characteristics of a group of people in terms of factors such as their age, sex, marital status, education, occupation, and relationship to the head of household.

What does a population include?

A population is defined as a group of individuals of the same species living and interbreeding within a given area. Members of a population often rely on the same resources, are subject to similar environmental constraints, and depend on the availability of other members to persist over time.

What is the difference between a community and an ecosystem?

If we put populations of different species together, that’s called a community. So, a community needs groups of different species to exist. When we add in the abiotic factors, or non-living things in an environment, we get an ecosystem.

Which group of organisms is a population?

A population is defined as a group of organisms of the same species that live in a particular area. There can be more than one population living within any given area. There can be a population of Saguaro Cacti, a population of Cactus Wrens and a population of Bark Scorpion living in the same areas.

What is biological aspect of population?

Biological aspect includes the living things of the environment. Human beings, animals, birds, insects, plants and vegetation are some examples of biological aspect. It is affected by the variations in climate, topography and altitude of the place.

What is the biological species concept?

The Biological Species Concept defines a species taxon as a group of organisms that can successfully interbreed and produce fertile offspring. According to that concept, a species’ integrity is maintained by interbreeding within a species as well as by reproductive barriers between organisms in different species.

What is the biological definition of a species?

A biological species is a group of organisms that can reproduce with one another in nature and produce fertile offspring.

When would we use the biological species concept quizlet?

Scientists categorize organisms into species based on their physical, genetic, and behavioral characteristics. The most common method for species differentiation is the biological species concept, which defines a species as a population of organisms that can interbreed to produce viable, fertile offspring.
