The variety of organisms on earth

The variety of organisms on earth is called biodiversity.

Biodiversity describes the richness and variety of life on earth. It is the most complex and important feature of our planet. Without biodiversity, life would not be sustained.

Biodiversity includes the number of different organisms and their relative frequencies in an ecosystem. It also reflects the organization of organisms at different levels.

Biodiversity holds ecological and economic significance. It provides us with nourishment, housing, fuel, clothing, and several other resources.

It also extracts monetary benefits through tourism. Therefore, it is very important to have a good knowledge of biodiversity for a sustainable livelihood.

animals organisms

Animal organisms are multicellular organisms. The animal body is composed of several cells performing specific functions, as opposed to bacteria and most protists, which are unicellular.

Animals and other organisms in an ecosystem have an ecological relationship between them that helps them survive.

The region in which populations interact with each other is called an ecosystem.

What are large areas with similar flora, fauna, and microorganisms?

The large areas with similar flora, fauna, and microorganisms are called biomes.

A biome is comprised of multiple ecosystems.

An ecosystem is a community and its physical environment.

A community consists of many different populations of living things.

A group of organisms of the same species that live in an area is called a population.

A community differs from a population in that communities evolve to have greater biomass and species richness in a process called succession, whereas in a population, any individual evolves as a result of genetic drift.

All the plants and animals in the world are made of

All the plants and animals in the world are made of cells. A cell is the basic building block of all organisms. 

It is the smallest unit of organization in the biosphere. A cell performs the life process to maintain the survival of an organism.

The study of biodiversity is called

The study of biodiversity is called biogeography.

Study of biodiversity

Biogeographic studies divide Earth’s surface into regions exhibiting differences in the average composition of flora and fauna.

It is thought that the present-day distribution patterns of plant and animal forms, as reflected in such biogeographic regions, are the result of many historical and current causes.

These causes include present climatic and geographic conditions, the geologic history of the landmasses and their climates, and the evolution of the taxon (e.g., genus or species) involved

. Investigators have found that rate of dispersal, adaptability to prevailing environmental conditions, and the age of the taxa being studied also have a significant impact on pattern and extent of distribution.

Ecologists organize biodiversity on three levels.

Ecologists organize biodiversity on three levels which are ecosystem diversity, species diversity, and genetic diversity.

  1. Ecosystem diversity: Ecosystem diversity is the variety of ecosystems in a given place. An ecosystem is a community of organisms and their physical environment interacting together. An ecosystem can cover a large area, such as a whole forest, or a small area, such as a pond.
  2. Species diversity: Species diversity is the variety of species within a habitat or a region. Some habitats, such as rainforests and coral reefs, have many species. Others, such as salt flats or a polluted stream, have fewer.
  3. Genetic Diversity: Genetic diversity refers to the variety of genes within a species. Each species is made up of individuals that have their own particular genetic composition. This means a species may have different populations, each having a  different genetic composition. To conserve genetic diversity, different populations of a species must be conserved.

Energy growth evolutionary and ecological describe different biological

Energy, growth, evolutionary and ecological describe different biological life cycles. The life cycle involves all those living organisms on the earth.

Energy, growth, evolution, and ecological describe different biological cycles

Interdependence in nature is illustrated by the transfer of energy(Energy cycle).

Ecological systems (ecosystems) have many biogeochemical cycles operating as a part of the system, for example, the water cycle, the carbon cycle, the nitrogen cycle, etc. All chemical elements occurring in organisms are part of biogeochemical cycles.

The organisms most likely to belong to the same species are those that comprise a population.

Population growth and increasing resource consumption affect biodiversity in two ways: they create pressure to convert wildlife habitats into agricultural and urban land, and they produce waste that pollutes habitats and poisons wildlife.

number of species that live in an area.

The number of species that live in an area is referred to as biodiversity.

Current estimates of global species diversity vary between 2 million and 100 million species, with a popular estimate of somewhere near 13 to 14 million.

The variety of organisms that inhabit the earth

The variety of organisms that inhabit the earth is called biodiversity. It can be used more specifically to refer to all of the species in one region or ecosystem. Biodiversity refers to every living thing, including plants, bacteria, animals, and humans.

Variety of organisms on earth

Most people recognize biodiversity by species, it is a group of individual living organisms that can interbreed. Examples of species include blue whales, white-tailed deer, white pine trees, sunflowers, and microscopic bacteria that can’t even be seen by the naked eye.

FAQ

What term includes the variety of species in an area of interest?

The term that includes the variety of species in an area of interest is biodiversity.

Due to humans’ evolving into intellectual creatures, we have surpassed other species in terms of population, and because of this, we have started to dominate other species. 

This dominance is clearly visible in the following data:
About one million plant and animal species face the threat of extinction.
At least 680 vertebrate species have gone extinct since the 16th century.
The majority of native species in land-based habitats have fallen by a minimum of 20% since the 1900s.
Extinction threatens more than 40% of amphibians.
Nearly 33% of reef-forming corals face the threat of extinction.
Extinction threatens more than a third of all marine mammals.

Which field of biology studies all aspects of biodiversity?

The field of biology that studies all aspects of biodiversity is Ecology.

Which of these choices does not describe an area that usually has a biologically diverse ecosystem?

A highly fragmented landscape is an area that usually does not have a biologically diverse ecosystem.
Landscape fragmentation can seriously impact the ability of wildlife managers to sustain species that require large blocks of undisturbed habitat. Land ownership, parcelization, and development can have significant impacts on landscapes.

Which statement best describes the term “biodiversity”?

The statement that best describes the term biodiversity is the enormous variety of life on Earth.
