Science Notes SPI 0807.5.4 Biodiversity Biodiversity: is the amount and variety of organisms that live in a given area at a given time. Measured 3 ways (1) Species Richness- Amount of different species (2) Evenness- Balance of the species (3) Genetic diversity- How closely the species are related Watch a Holt Online Visual Concept.

Science Notes SPI 0807.5.4 Biodiversity SPI 0807.5.4 (Biodiversity) Identify several reasons for the importance of maintaining the earth’s biodiversity. Here are 8 Reasons to Maintain Biodiversity 1) To feed the world 2) To provide more medicine 3) To maintain our economies 4) To provide life support for our biosphere 5) To avoid disrupting food webs 6) To satisfy human curiosity 7) To preserve nature's beauty 8) To respect life in all its forms

Reasons to Maintain Biodiversity SPI 0807.5.4 Biodiversity Notes Science Reasons to Maintain Biodiversity 1) To feed the world 90 percent of the world's food comes from only 20 plant species Examples: Corn, Rice, Wheat, Soybeans, etc. If a disease or natural disaster damages or wipes out one or more of these crops, famine would result (millions could starve). With more varieties of these types of plants, we increase our chances of avoiding and/or reducing the impact of a famine.
