| Robert Fraley (monsanto; cheif technical officer) | PhD microbiology and biochemistry; for GMOs |
| Hawaiian papaya was treated for | ringspot virus |
| Ugandan bananas were treated for | banana wilt (bacteria) |
| ecosystem | collective function of organisms and their environment |
| what are the components of an ecosystem | food chains, nutrient cycles, plant succession, competitive exclusion, diversity |
| agroecosystems | ecosystems modified to produce food, fiber and shelter |
| how are agroecosystems and ecosystems differ | agroecosystems are the foundation of human societies while ecosystems are the foundation of nature |
| ecological pyramids | depict the transfer of energy and biomass from producers to consumers |
| how do ecological pyramids help us understand biological magnification | depict how minuscule amounts of contaminate at the lower levels of a food chain leads to large buildup of contaminant at the top |
| plant succession | natural changes in plant community over long periods of time |
| example of plant succession | Bastrop, Texas |
| how are natural ecosystems and agroecosystems different | nutrient cycles are altered, breeding, management, diversity and inputs requirements are different |
| how are agroecosystems and natural ecosystems similar | none to some loss of soil and nutrients |
| what are the risks associated with simplified agroecosystems | plant pathogens, topsoil loss |
| ecology | science dealing with mutual relationships among biological organisms |
| corn-soybean rotation | corn one growing season, soybean the next and repeat |
| what is soil | medium for the production and growth of plants and crops |
| what are the three important functions served by soils | anchorage for plants, storage of water or nutrients for plant uptake, habitat for soil organisms |
| identify the five soil forming factors | parent material, climate, biological factors (organisms), topography, time |
| soil profile | the vertical section through the soil extending from the surface to the unweathered rock of the crust layer |
| how many soil orders are in texas | 7 |
| what is organic matter | portion of the soil that includes animal and plant residues in various stages of decay |
| what are the five different functions of organic matter in soil | sequestration of nutrients, source of nutrients, soil aggregation and structure, water storage, chemical sequestration |
| what is C:N ratio | carbon:nitrogen |
| what does the C:N ratio affect | influences the rate of decomposition of plant materials in the soil |
| gravitational water | drains readily through the soil |
| field capacity | water is held in the pore spaces but is readily available to plants |
| permanent wilting point | water is held tightly by soil particle and is not available to plants |
| soil fertility | ability of a soil to supply important chemical nutrients or essential elements to plants |
| soils are ecosystems for | plants, bacteria, fungi, insects and invertebrates |
| soil is the | biochemically weathered, uppermost portion of the earth's crust |
| mollisols | dark colored surface horizon that is enriched with organic matter; formed under grasslands; found in high plains |
| vertisols | very clayey that have deep, wide cracks during dry periods; found in blackland prairie |
| aridosols | dry soils of the deserts; used for rangeland and irrigation; found in trans-pecos |
| ultisols | highly weathered soils that have a subsurface horizon enriched with clay, under forestation; found in east texas |
| alfisols | general fertile soils found under forest vegetation |
| entisols | little evidence of soil formation; found in cool and dry places |
| inceptisols | young soils with weakly developed subsurface horizons; found between Brazos and Colorado rivers |
| three types of rock | sedimentary, igneous, metamorphic |
| sedimentary | formed when wind and water deposit minerals |
| lgneous | formed under extreme volcanic heat, followed by periods of cooling and hardening |
| metamorphic | formed by heat and pressure on other types of rocks |
