Quarter 4 - ALL ABOUT OUR BIODIVERSITY.pptx

1. BIODIVERSITY PREPARED BY: MA’AM AIRA MAE

2. What is Biodiversity? refers to the variety of life that can be found on Earth. It is composed of ecosystems, species, and genetic diversity that includes all levels of biological organization. It is the combination of two words, “biological” and “diversity” .

3. What is Ecosystem? A geographic region where plants, animals, and other species work together to form a framework of life, including the weather and landscape. Ecosystems are comprised of bioti c or living, as well as abiotic or non-living components.

4. TYPES OF BIODIVERSITY 1. HIGH BIODIVERSITY T here is a great range of organisms interacting differently. Implies it has the largest number of species that live in it.

5. TROPICAL RAINFOREST AQUATIC ECOSYSTEM

6. Advantages of having High Biodiversity I ncreased ecosystem functioning. R educe vulnerability to disasters. R ich medicinal resources and pharmaceutical drugs. H ealthier population of organisms.

7. 2. LOW BIODIVERSITY L ow biodiversity refers to an ecosystem with minimum interactions between and among organisms. U sually led to habitat loss due to human destructions and natural disasters. TYPES OF BIODIVERSITY

8. 2. LOW BIODIVERSITY There may be an inadequate supply of food, high temperature, and scarcity of water sources, leading to low biodiversity. TYPES OF BIODIVERSITY

9. DESERT ECOSYSTEM TUNDRA ECOSYSTEM

10. DISADVANTAGE OF LOW BIODIVERSITY Fewer species at different tropical levels. Lower competition and Lesser food sources. T he energy and nutrient pathways are less numerous . Less productive and low sustainable ecosystem

11. IMPORTANT CONTRIBUTION OF BIODIVERSITY E conomic biodiversity supplies raw materials to humans for consumption and production. Biodiversity offers functioning ecosystems that provide oxygen, clean air and water, plant pollination through plant activities and plants as the food for animals, pest control, wastewater treatment, and many ecosystem services with ecological life support.

12. Causes why species decline aside from the natural processes H – habitat destruction I – invasion of introduced species P – Population increase P - Pollution O – Overcollection / Overharvesting of resources

13. WHAT IS YOUR CONTRIBUTION IN PROTECTION OR CONSERVATION OF BIODIVERSITY?

14. “ACT NOW, NO ONE CAN DO THIS FOR YOU NOR FOR US!”
