Question

explain with suitable example genetic diversity , species diversity and ecosystem diversity ​

Answer 1

Answer:

1. Biodiversity is a complex term that includes not only the variety of different animals (species diversity) but also the difference between animals of the same species (genetic diversity) and between ecosystems (ecosystem diversity).

Answer 2

Answer:

Genetic diversity exists as the product of the recombination of genetic material in the procedure of inheritance. It varies with time and space.

Explanation:

“Genetic diversity exists defined as genetic variability present within species.”

Genetic diversity exists as the product of the recombination of genetic material in the procedure of inheritance. It varies with time and space.

Sexual reproduction is important in maintaining genetic diversity as it provides unique offspring by combining the genes of parents.

Mutation of genes, genetic drift, and gene flow exist also responsible for genetic diversity.

Genetic Diversity Examples

• Various breeds of dogs. Dogs exist selectively bred to get the desired traits.
• Different combinations of rose flowers, wheat, etc.
• There are more than 50,000 types of rice and more than a thousand varieties of mangoes found in India.
• Different varieties of medicinal plant Rauwolfia vomitoria present in various Himalayan ranges differ in the amount of chemical reserpine produced by them.

“Species diversity exists defined as the number of various species present in an ecosystem and relative abundance of each of those species.” Diversity exists greatest when all the species current is equally abundant in the area.

Species diversity exists as the measure of biological diversity observed in a certain ecological community indicating several species or species richness in an ecological community.

Example – woodland forest comprising 4-5 distinct species of trees. Tens of hundreds of fish species, coral, and crustaceans are found in a distinct reef, etc.

Ecosystem Diversity can be described as the combination of different habitats, communities, and ecological processes. A biological community is determined by the species that occupy a certain area and the interactions between those species.

Grasslands, tundra's, deserts, rainforests, and terrestrial and marine ecosystems, are some examples of ecosystems that are diverse and contribute a lot to forming a well-balanced environment.
