Which is an example of unity in diversity?

Which of the following is an example of “unity of diversity”? All organisms, including prokaryotes and eukaryotes, use essentially the same genetic code. The structure of DNA is the same in all organisms. The forelimbs of all mammals have the same basic structure, modified for different environments.

How is unity and diversity in the living world represented?

Every living organism has a level of organization. Diversity and unity of life, interdependence of organisms, and evolution of life. How is the unity and diversity in the living world represented. Scientists think that all living things have descended with modification from a single common ancestor.

What accounts for both the unity of life and the diversity of life?

Answer. Biological evolution explains both the unity and the diversity of species and pro- vides a unifying principle for the history and diversity of life on Earth. Biological evolution is supported by extensive scientific evidence ranging from the fossil record to genetic relationships among species.

What are the different ways of diversity in living things?

Biodiversity can be described and measured at three different levels: species, genetic, and ecosystem diversity. Species diversity refers to the number of different species in an ecosystem or on Earth as a whole. This is the commonest way to measure biodiversity.

Which is the best example for genetic diversity?

Examples of Genetic Diversity

• Domestic Dogs. Humans have created distinct breeds of dogs within the species by selectively breeding individuals with traits that they want.
• Woody Plant Species. Woody plants, such as trees, tend to have more genetic diversity, on the whole, than vascular plants, such as grasses.
• Generalist vs.
• The Cheetah.

What is genetic diversity with example?

Genetic diversity is the total number of genetic characteristics in the genetic makeup of a species, it ranges widely from the number of species to differences within species and can be attributed to the span of survival for a species.

How do we get genetic diversity?

Genetic variation can be caused by mutation (which can create entirely new alleles in a population), random mating, random fertilization, and recombination between homologous chromosomes during meiosis (which reshuffles alleles within an organism’s offspring).

Why genetic diversity is important?

Genetic variation is an important force in evolution as it allows natural selection to increase or decrease frequency of alleles already in the population. Genetic variation is advantageous to a population because it enables some individuals to adapt to the environment while maintaining the survival of the population.

What is ecosystem diversity with example?

Ecosystem diversity deals with the variations in ecosystems within a geographical location and its overall impact on human existence and the environment. An example of ecological diversity on a global scale would be the variation in ecosystems, such as deserts, forests, grasslands, wetlands and oceans.

What are the examples of diverse ecosystem?

Some examples of ecosystems that are rich in diversity are:

• Deserts.
• Forests.
• Large marine ecosystems.
• Marine ecosystems.
• Old-growth forests.
• Rainforests.
• Tundra.
• Coral reefs.

Why is it important to have diversity in an ecosystem?

Biodiversity boosts ecosystem productivity where each species, no matter how small, all have an important role to play. A larger number of plant species means a greater variety of crops. Greater species diversity ensures natural sustainability for all life forms.

What three type of diversity can biodiversity be broken down into?

Usually three levels of biodiversity are discussed—genetic, species, and ecosystem diversity. Genetic diversity is all the different genes contained in all individual plants, animals, fungi, and microorganisms. It occurs within a species as well as between species.

What are the 3 intertwined features of biodiversity?

Biodiversity is usually explored at three levels – genetic diversity, species diversity and ecosystem diversity. These three levels work together to create the complexity of life on Earth.

What is the pattern of biodiversity?

Biodiversity is the variety observed in organisms at every level of biological organization. As ecologists studied biodiversity in the environment, they observed a regular pattern in which diversity was distributed over the entire area of the planet.

What are the 5 causes of biodiversity loss?

Five main threats to biodiversity are commonly recognized in the programmes of work of the Convention: invasive alien species, climate change, nutrient loading and pollution, habitat change, and overexploitation.

What are the major causes of biodiversity?
