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. We have moved all content for this concept to for better organization. Biodiversity is usually explored at three levels - genetic diversity, species diversity and ecosystem diversity. Biodiversity is a broad term for biological variety, and it can be measured at a number of organizational levels. 20.1) Biotechnology and genetic engineering Biotechnology is the application of biological organisms, systems or processes to manufacturing and service industries. Proteins are the most abundant organic molecules present on earth. Without biodiversity, all humans would basically be clones of each other. Uses of biodiversity: Ø Biodiversity, besides its ecological significance, provides a socio-economic asset to the nation. Productive use (2). Biology II. 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. For example deserts and arctic regions naturally have low a biodiversity due to the harsh environment. ecosystem that they are in and are extremely important in the function and structure of that ecosystem. Best CBD Oil for Anxiety 5.3 Importance of Biodiversity The Biodiversity Crisis. Why Biodiversity is Essential for Sustainable Development. Discusses the benefits of biodiversity. Search for: The Importance of Biodiversity to Human Life. These three levels work together to create the complexity of life on Earth. Biodiversity refers to the variety and variability of life on Earth. It … Proteins are the polymers made up of thousands of amino acids linked via peptide bonds. It covers the whole of Topic 3 which is Classification and Biodiversity. Indirect use (1). For example, the richness of diversity allows medicines and foods to be naturally available. Genetic diversity. Biodiversity. Biodiversity is a measure of how many different species live in an ecosystem. Consumptive use (3). 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. 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. The cell cycle including G1 (in which some organelles are replicated), S phase (in which DNA is replicated) and G2 then mitosis. I would aim to include the following: 1. Biodiversity or biological diversity is a term that describes the variety of living beings on earth. means having as wide a range of different species in an ecosystem as possible. But when it loses too much, it hits a tipping point and falls off a cliff. Each specification objective is covered in just the right amount of detail with clear diagrams and clever slide animations. This A-Level Biology section of Revision Science explains biodiversity classification including examples. Having a low biodiversity isn’t necessarily an issue. It enables the population to adapt to its environment and respond to natural selection. Genetic engineering involves the transfer of genes from one organism to (usually) an unrelated species. Biodiversity, also called biological diversity, the variety of life found in a place on Earth or, often, the total variety of life on Earth. 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. We provide detailed revision materials for A-Level Biology students and teachers. Why not? 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). the population of the species falls below a critical level; Biodiversity. That’s why an ecosystem that’s losing biodiversity only declines slowly at first. Both processes often make use of bacteria because of their ability to make complex molecules (eg.
