why is biodiversity important a level biology

What is biodiversity? Biodiversity describes the richness and variety of life on earth. How does biodiversity vary spatially across the globe? Understanding how biodiversity evolved and is evolving on Earth and how to correctly use and interpret biodiversity data is important for all students interested in conservation biology and ecology, whether they pursue careers in academia or as policy makers and other professionals (students graduating from our programs do both). Productive use: Ø Products commercially harvested from biodiversity for exchange in market. Indirect use (1). Genetic diversity is the variety of genes within a species. Ecological diversity (or biodiversity) is the total amount of variety within life on earth. Where is biodiversity highest and lowest? Genetic engineering involves the transfer of genes from one organism to (usually) an unrelated species. For example, the richness of diversity allows medicines and foods to be naturally available. Discusses the benefits of biodiversity. So really, the important shift here is to stop thinking of the planet as a physical system but as a linked biological and physical system. An example of a keystone species is a shark. Without biodiversity, life would not sustain. Human activities like changing land use, deforestation and peat bog destruction reduce this. Proteins are the most abundant organic molecules present on earth. Traditionally, ecologists have measured biodiversity by taking into account both the number of species and the number of individuals in each of those species. Biodiversity or biological diversity is a term that describes the variety of living beings on earth. Without biodiversity, all humans would basically be clones of each other. Biodiversity. Consumptive use (3). Please update your bookmarks accordingly. Biodiversity is a measure of how many different species live in an ecosystem. It is important in natural as well as artificial ecosystems. A threat to biodiversity poses a threat to humankind. These three levels work together to create the complexity of life on Earth. The term biodiversity was coined in 1985. At least 40 percent of the world’s economy and 80 percent of the needs of the poor are derived from biological resources. Over 22,000 learners have used our materials to pass their exams. 20.1) Biotechnology and genetic engineering Biotechnology is the application of biological organisms, systems or processes to manufacturing and service industries. 5.3 Importance of Biodiversity The Biodiversity Crisis. The number of animals living on the Earth has plunged by half since 1970. It is a very broad and diverse field. I would aim to include the following: 1. It enables the population to adapt to its environment and respond to natural selection. Biodiversity is usually explored at three levels - genetic diversity, species diversity and ecosystem diversity. Genetic diversity. means having as wide a range of different species in an ecosystem as possible. Also, it boosts the productivity of ecosystems because each organism has a specific job.. A bunch of different organisms all having different abilities is more effective than having a group of identical organisms wandering around and only having the ability to do one job. An indicator species is a species that serves as a measure to the abiotic and biotic factors of the ecosystem. Biodiversity is increased by genetic change and evolutionary processes and reduced by habitat destruction, population decline and extinction. We value biodiversity for many reasons, some utilitarian, some intrinsic. It … There are three levels of biodiversity: 1. Both species diversity and genetic diversity are important within a habitat, because they make it more likely that the habitat can adapt successfully to changing conditions. ‘Biodiversity’ comes from two words: ‘biological’, which means relating to biology or living organisms, and ‘diversity’, meaning a range of different things or variety. Having a low biodiversity isn’t necessarily an issue. Module 23: Ecology. ecosystem that they are in and are extremely important in the function and structure of that ecosystem. proteins) and their […] Both processes often make use of bacteria because of their ability to make complex molecules (eg. There is a growing recognition that the level of biodiversity is an important factor in influencing the resilience of ecosystems to disturbance. The more biodiversity, the stronger the ecosystem, the better it functions, and the better it can adapt to changes. The number of tigers has plunged by 97% in the last century. Search for: The Importance of Biodiversity to Human Life. The natural disaster prevention mechanisms in most ecosystems and other free services we all get from the surrounding environment are not easily replaceable or replicable, so maintaining biodiversity is important. Biology is the study of life. Biodiversity is also considered by many to have intrinsic value—that is, each species has a value and a right to exist, whether or not it is known to have value to humans. Biodiversity is a broad term for biological variety, and it can be measured at a number of organizational levels. A common measure of this variety, called species richness, is the count of species in an area. It may not be clear why biologists are concerned about biodiversity loss. Altogether, the food, commercial forestry and ecotourism industries could lose US$ 338 billion per year if the loss of biodiversity continues at its current pace. For economic and various life support reasons, it is very important to protect and preserve biodiversity. It is a natural science. Long chains of amino acids known as polypeptides fold around themselves in several ways to form complex structures called proteins. This of it like this. Biological diversity or biodiversity refers to the variety of organisms that exist on the earth, their interrelationships as well as their relationship with the environment. Biodiversity is important to humans for many reasons. Productive use (2). Even knowledge of taxonomic diversity, the best known dimension of biodiversity, is incomplete and strongly biased toward the species level, megafauna, temperate systems, and components used by people. Biodiversity, also called biological diversity, the variety of life found in a place on Earth or, often, the total variety of life on Earth. So you want to study biology…Duh! Biodiversity is often a topic used in A level biology to introduce ecology, providing ample opportunities to undertake practical investigations, compile results which can be analysed using species diversity index and subsequently interpreted to compare particular habitats. In fact, I consider it as the science of the 21st century. What is biodiversity and why does it matter to us? Each specification objective is covered in just the right amount of detail with clear diagrams and clever slide animations. It covers the whole of Topic 3 which is Classification and Biodiversity. Biologists estimate that species extinctions are currently 500–1000 times the normal, or background, rate seen previously in Earth’s history. That would be ridiculous. Biodiversity is variation at … Best CBD Oil for Anxiety That’s why an ecosystem that’s losing biodiversity only declines slowly at first. This is a fully editable PowerPoint presentation designed specifically for the new Edexcel A Level Biology B Specification for first teaching in 2015. We provide detailed revision materials for A-Level Biology students and teachers. Genetic diversity: It refers to the variation in gene within a species. Read first: Gaston, K.J. * Biodiversity also refers to number of different species living in a particular region. Diversity in marine habitats For example deserts and arctic regions naturally have low a biodiversity due to the harsh environment. The current high rates will cause a precipitous decline in the biodiversity of the planet in the next century or two. Documenting spatial patterns in biodiversity is difficult because taxonomic, functional, trophic, genetic, and other dimensions of biodiversity have been relatively poorly quantified. An example would be certain types of moss since they can indicate the level of nutrition in the soil and the acidity. the population of the species falls below a critical level; Biodiversity. This means we value biodiversity both for what it provides to humans, and for the value it has in its own right. It is the most complex and important feature of our planet. 2000, Global patterns in biodiversity, Nature, 405, 220-227 The paper by Gaston (2000) is an excellent place to start researching the spatial patterns of biodiversity, and some of the theories proposed to explain these patterns. A-Level Biology does pretty much what it says on the tin. Biodiversity refers to the variety and variability of life on Earth. They are present abundantly in every living cell. Biodiversity is a broad term for biological variety, and it can be measured at a number of organizational levels. Cycles occur all over biology and this is a good example of a question where you should be able to mention an extensive range of subjects. Biodiversity is important to most aspects of our lives. Ø Uses related to biodiversity can be grouped into three categories: (1). The cell cycle including G1 (in which some organelles are replicated), S phase (in which DNA is replicated) and G2 then mitosis. It can be the cause of various grave problems like pollution, habitat loss, resource exploitation, climate change, species extinction, disease outbreak, and so on. Biodiversity is important, more than just the 'I want my children to enjoy it' reason. Traditionally, ecologists have measured biodiversity by taking into account both the number of species and the number of individuals in each of those species. But when it loses too much, it hits a tipping point and falls off a cliff. Why not? Biodiversity is good for the economy. We have moved all content for this concept to for better organization. Uses of biodiversity: Ø Biodiversity, besides its ecological significance, provides a socio-economic asset to the nation. This A-Level Biology section of Revision Science explains biodiversity classification including examples. Biology II. Why Biodiversity is Essential for Sustainable Development.
