Cornell Notes for Miller Chapter 4
Biodiversity
* The biodiversity found in genes, species, ecosystems, an ecosystem processes is vital to sustaining life on earth. * Part of the Earth’s natural capital * Biodiversity is the variety of the earth’s species, the genes they contain, the ecosystems in which they live, and the ecosystem processes such as energy flow and nutrient cycling that sustain all life. * Renewable resource * Plays a role in preserving the quality of the air and water and maintaining the fertility of soils.
Genetic diversity * The variety of genetic material within a species or a population * Enables life on earth to adapt to and survive dramatic environmental changes.
Species diversity * The number and abundance of species present in different communities
Ecosystem
Diversity * The variety of terrestrial and aquatic ecosystems found in an area or on the earth (deserts, grasslands, forests, etc.). * Each ecosystem is a storehouse of genetic and species diversity.
Functional
Diversity * The biological and chemical processes such as energy flow and matter recycling needed for the survival of species, communities, and ecosystems.
Biological
Evolution
By natural
Selection
* The scientific theory of evolution explains how life on earth changes over time through changes in the genes of population. * Populations evolve when genes mutate and give some individuals genetic traits that enhance their abilities to survive and to produce offspring with these traits (natural selection). * Biological evolution-the process whereby earth’s life changes over time through changes in the genes of populations. * The idea of evolution came from early Greek philosophers, but Charles Darwin came up with an explanation of evolution. * Russell Wallace proposed the concept of natural selection, but once again Darwin explained natural selection. * Darwin and Wallace observed that- * There is
