QuestionAnswer
What stage of the carbon cycle: Carbon enters the atmosphere by respiration in organisms, combustion, decomposition and decay carbon cycle stage 1
What stage of the carbon cycle: Carbon Dioxide is absorbed by producers in photosynthesis. Plants take in CO2 from the atmosphere in order to produce energy in the form of sugar via photosynthesis using sunlight. carbon cycle stage 2
What stage of the carbon cycle: Carbon transfer from organism to organism. Animals eat plants consuming the carbon content and animals eat other animals transferring carbon from one to another. carbon cycle stage 3
What stage of the carbon cycle: Animals and plants die, and the organisms are eaten by decomposers. Decomposers respire to release CO2 back into the air. Carbon enters the atmosphere through respiration and decomposition. carbon cycle stage 4
____________ traps the heat in the atmosphere which causes the world's temperature to rise. greenhouse gases
_________ occurs when carbon dioxide mixes with water in the ocean and lowers the pH. ocean acidification
A complex network of food chains. food webs
Shows how each living thing gets food, and how nutrients and energy are passed from organism to organism. It begins with plant life and end with animal life. food chain
The layer of gases surrounding the earth or another planet. atmosphere
all the waters on the earth's surface, such as lakes and seas, and sometimes including water over the earth's surface, such as clouds. hydrosphere
The areas of the earth occupied by living organisms. biosphere
The solid part of the earth consisting of the crust and outer mantle. geosphere
The curved path of a celestial object or spacecraft around a star, planet, or moon, especially a periodic elliptical revolution. sphere interactions
move or cause to move into a sloping position. tilt
a slowly moving mass or river of ice formed by the accumulation and compaction of snow on mountains or near the poles. glacier
the process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water. photosynthesis
The process through which cells convert glucose into energy and nutrients using oxygen. cellular respiration
a gradual increase in the overall temperature of the earth's atmosphere generally attributed to the greenhouse effect caused by increased levels of carbon dioxide, chlorofluorocarbons, and other pollutants. global warning
a measure of the number of deaths per unit of time divided by the size of the population. mortality rate
The WARM PHASE of the El Niño–Southern Oscillation (ENSO) and is associated with a band of warm ocean water that develops in the central and east-central equatorial Pacific. el nino
The COOLER PHASE of the El Niño–Southern Oscillation (ENSO) and is associated with a band of cooler ocean water that develops in the central and east-central equatorial Pacific la nina
_____________ result because of thermal expansion caused by warming of the ocean (since water expands as it warms) and increased melting of land-based ice, such as glaciers and ice sheets. rising sea levels
Increasing concentrations of greenhouse gases are preventing heat radiated from Earth’s surface from escaping into space as freely as it used to; most of the excess heat is being stored in the upper ocean. This results in ____________. rising ocean temperatures
movement from one part of something to another. migration
_______________ feedback loop amplify (increases) the negative effect of each climate. positive
_______________ feedback loop diminish (decreases) the negative effect of each climate. negative
a biological community of interacting organisms AND their physical environment. (living and nonliving) ecosystem
the weather conditions prevailing in an area in general or over a long period climate
________ is a measure of hydrogen ion concentration, a measure of the acidity or alkalinity of a solution. The pH scale usually ranges from 0 to 14. pH
what are solutions to the CO2 problem? solar panels, wind energy, eliminating emissions, planting trees, etc.
a region of oxygen-depleted water off the Louisiana and Texas coasts that's harmful to sea life dead zones
____________ is an area along the Mississippi River between Baton Rouge and New Orleans in the River Parishes of Louisiana which contains numerous industrial plants with clusters of cancer patients. cancer alley
__________ is a measurement of population size per unit area, example: population size divided by total land area. Population density
___________ is the contamination of water bodies, usually as a result of human activities. water pollution
_______ is any single identifiable source of pollution from which pollutants are discharged, such as a pipe, ditch, ship or factory smokestack point source pollution
_________ is pollution that comes from many diffuse sources. It is caused by rainfall or snowmelt moving over and through the ground nonpoint source pollution
What are some examples of pollution? runoff, sediment, chemical, air, fertilizer, etc
_______ is a condition where an organism is deprived of adequate oxygen supply at the tissue level. Example: nutrient runoff, mostly from over-application of fertilizer on agricultural fields during the spring. hypoxic condition
_________ is an environmental condition that limits the growth, abundance, or distribution of an organism or a population of organisms in an ecosystem limiting factor
the maximum population size of the species that the environment can sustain indefinitely, given the food, habitat, water, and other necessities available in the environment carrying capacity
the increase in the number of individuals in a population population growth
Organisms that require good water quality to survive. They may require high dissolved oxygen levels, or clear, nonturbid waters, or they may be predators that require an ample source of prey. They are said to be ____________. pollution sensitive
Organisms that can survive in poor water quality. They often have adaptations that allow them to survive in water with low dissolved oxygen, turbid waters or nutrient-enriched waters. They are said to be __________. pollution tolerant
Resources that exist without actions of humankind. Examples: wood, oil, gas, water, etc. natural resource
