1. TYPES OF BIODIVERSITY AND THE ROLE IN ECOSYSTEMS BIODIVERSITY

2. Learning Objectives Identify and describe the different types of biodiversity Understand how our ecosystems help us with food and medicine production.

3. What is Biodiversity? The term Biodiversity was first coined by Walter G. Rosen in 1986. The word Biodiversity originates from the Greek word BIOS = LIFE and Latin word DIVERSITAS = VARIETY or DIFFERENCE. The whole word BIO DIVERSITY generally therefore means: VARIETY OF LIFE. Biodiversity is the degree of variation of life. It is a measure of the variety of organisms  present in different ecosystems.

4. Types Of Biodiversity Species Biodiversity Genetic Biodiversity Ecosystem Biodiversity

5. Biodiversity Biodiversity, which refers to the range of life forms in an ecosystem, biome, or across the Earth, is essential for preserving the well-being and equilibrium of ecosystems. This encompasses genetic diversity within species, diversity between species, and diversity of ecosystems.

6. Biodiversity, which refers to the range of life forms in an ecosystem, biome, or across the Earth, is essential for preserving the well-being and equilibrium of ecosystems. This encompasses genetic diversity within species, diversity between species, and diversity of ecosystems.

7. Species Biodiversity Species Diversity  is the effective number of different species that are represented in a collection of individuals

8. Genetic Biodiversity Genetic diversity , the level of biodiversity refers to the total number of genetic characteristics in the genetic makeup of a species.

9. Ecosystem Biodiversity Ecosystem diversity refers to the diversity of a place at the level of ecosystems. The term differs from biodiversity, which refers to variation in species rather than ecosystems.

10. BENEFITS OF BIODIVERSITY Consumptive value: Food/Drink Fuel Medicine Batter crop varieties Industrial Material Non-Consumptive Value : Recreation Education and Research Traditional value

11. c CONSERVATION OF BIODIVERSITY Biodiversity inventories Conserving Biodiversity in protected Habitats- In situ conservation Ex situ conservation Seed Bank, Gene Bank, Pollen Bank, DNA Bank

12. Decomposition and Soil Fertility A diverse community of decomposers like bacteria, fungi, and invertebrates breaks down organic matter, recycling nutrients and improving soil structure. This process supports plant growth and ecosystem health by enhancing soil fertility. Earthworms aerate soil, fungi aid in nutrient uptake, and plants flourish in this nutrient-rich environment. Sustainable agricultural practices benefit from understanding and supporting this ecosystem. Healthy soils act as carbon sinks, mitigate climate change, and protect water quality, highlighting the global importance of maintaining soil fertility.

13. Pollination and Seed Dispersal Pollinator Diversity: A variety of pollinators, including insects, birds, and bats, ensures the pollination of many plant species, leading to successful reproduction and maintenance of plant diversity. Seed Dispersal: Different animal species contribute to seed dispersal, facilitating plant colonization and genetic diversity across the landscape. Biodiversity is vital for the pollination of crops, which directly affects global food security .

14. Climate Regulation Carbon Sequestration: Diverse ecosystems, like tropical rainforests and wetlands, are crucial for capturing carbon dioxide from the atmosphere, thereby playing a vital role in regulating the global climate. Temperature and Water Regulation: Biodiverse ecosystems help in regulating local temperatures and maintaining the hydrological cycle, which impacts climate patterns.

15. How do different ecosystem help us? Food and Medicine: Biodiverse ecosystems provide a wealth of resources, including food, medicinal plants, and raw materials, essential for human survival and well-being. Cultural and Recreational Value: Biodiversity contributes to the cultural, aesthetic, and recreational value of natural landscapes, enhancing human quality of life and promoting conservation efforts.

16. Scientific and Educational Value Research Opportunities: Biodiversity offers vast opportunities for scientific research, leading to discoveries in fields such as genetics, medicine, and ecology. Education and Awareness: Diverse ecosystems serve as natural classrooms for education and raising awareness about environmental conservation.
