2/2/2011 1 Ecology “Study nature, love nature, stay close to nature. It will never fail you.” Frank Loyd Wright The Green and Black Poison Dart Frogs (Dendrobates auratus) are disappearing due to habitat destruction in South America. Connections in Nature ECOLOGY : The study of how (living) and ABIOTIC (non-living) environment, including soil, water, sun, and other organisms. ECOLOGICAL DEPENDANCE ON THE HONEY BEE throughout North America. Research suggested that 36% of North American hives have been lost to CCD. Honey bees are natural pollinators and are integral to the reproductive capabilities of plants. Without plant pollination, ecologists predict ecosystem dysfunction on a massive scale. Smallest unit of matter Atoms combine to have new properties Molecules combine to form the smallest unit of life Cells work together Organisms of the same species living together Populations of different species living in a defined space Communities interact with biotic and abiotic environment All parts of Earth where life can exist Biosphere Ecosystem Community Population Organism Cell Molecule Atom Life is Made Up of Cells Cells are the smallest unit of life. They are the most fundamental component of life‟s structure and function. All living things are composed of cells. Cell Biology SURFACE OF A CELL MEMBRANE Stem Cells Nerve Cells Bacteria Cells Plant Cells Biodiversity Biodiversity refers to all species on earth and all genes within these species. Biodiversity is a renewable resource, but it depends on ecosystem processes (such as nutrient cycling and energy flow) to be sustained. Genetics is the Key to Biodiversity LIVING ORGANISMS : The human body contains trillions of cells, each with an identical set of genes. Depending on the type of cell, genes can be turned on and off at different times. CELLS : Cells make proteins based on instructions provided by the DNA. The proteins are the structural and functional components of the cell.
