1. INTRODUCTION Biodiversity term used for the variety and variability between all types of living organisms such as microorganisms, plants and animals available in a particular area covered by natural conditions. The term biological diversity first coined by Norse and Mc Mangus in 1980 (Rawat and Khare, 2010). According to the U.S. Office of Technology Assessment (1987), biological diversity is the variety and variability among living organisms and the ecological complexes in which they occur. Biological
Germplasm can be a leaf, a piece of stem, pollen or even just a few cells from a plant (3). It is a living tissue that grows into a new plant (3). National Plant Germplasm System global food is an availability and security for the agricultural production. The importance of germplasms is to produce plants for food, fibers, animal feeds, industrial and medicinal purposes, and for landscape and ornamental uses (4). With the increasing knowledge, many farmers are learning how to plant breeders, increase
What exactly is Biodiversity? Biodiversity is generally defined as “the existence of many different kinds of plants and animals in an environment.” (Merriam Webster Dictionary, n.d.) However, there is no single definition for biodiversity. One definition for biological diversity is “a diversity among and within plant and animal species in an environment” (Biological Diversity, n.d.). Biodiversity can also be defined as “the number and variety of organisms found within a specified geographic region”
‘Define Biodiversity and using examples, explain why it is important’ Biodiversity is the variety of life on earth. A fuller definition is given in the Convention on Biological Diversity (CBD) from the 1992 Earth summit: ‘Biodiversity is the variability among living organisms from all sources, including terrestrial, marine, and other aquatic ecosystems and the ecological complexes of which they are part ; this includes diversity within species, between species and of ecosystems’ (Hambler, C., 2004
Biodiversity a.Biodiversity- is the degree of variation of life. It is a measure of the variety of organisms present in different ecosystems. This can refer to genetic variation, ecosystem variation, or species variation (number of species) within an area, biome, or planet. Terrestrial biodiversity tends to be highest near the equator, which seems to be the result of the warm climate and high primary productivity. Biodiversity is not distributed evenly on Earth. It is the richest in the tropics
Nations, concerning the environmental protection of Antarctica. Increasing concerns over loss species and poorer nations in the lack of resources lead to these three major issues, biodiversity, global climate change, and sustainable development in which the paper will discuss. Keywords: biodiversity, global climate change, sustainable development International Environmental

other: • Biodiversity • Sustainability • Adaptations Sustainability and biodiversity go hand-in-hand. Sustainability is the ability to maintain valued qualities in a physical environment. Those qualities come from the biodiversity of the environment. Biodiversity is the variability among living organisms from all sources. Biodiversity advances an ecosystems productivity and each species has an important role to fulfill. If those roles are disturbed, productivity slows down and biodiversity decreases
Biodiversity is the variability of the earth’s species, the genes they contain, the ecosystems in which they live, and the ecosystem processes, such as energy flow and nutrient cycling that sustain all life. (Miller & Spoolman, 2009. pg. 50) It involves many of the levels of organization of life, including genetic diversity species diversity, ecological diversity, and functional diversity. Biodiversity makes up the structure of the ecosystems and habitats that support essential living resources
Marine biodiversity Definition: Marine biodiversity refers to the species richness and abundance of genes, species and habitats in the world 's oceans and seas. And since the world is covered with approximately 70% water the amount of life in the oceans is enormous. According to the definition of the Convention on Biological Diversity, biodiversity is the variability among living organisms from all sources, including inter alia, terrestrial, marine and other aquatic ecosystems and the ecological
