Thermal Energy: Random kinetic energy possessed by objects in a material at finite temperature.
Photosynthesis: The process by which plants and other photoautotroph generate carbohydrates and oxygen from carbon dioxide, water, and light energy in chloroplasts
Producer: A producer is anything that can make its own food, like plants. Producers are usually the start of the food chain.
Cellular Respiration: The series of metabolic processes by which living cells produce energy through the oxidation of organic substances.
Consumer: animals or plants that cannot make their own food. They must eat or consume plants and animals for food
Ecological Niche: a term describing the relational position of a species or population in its ecosystem to each other
Food Chain: A succession of organisms in an ecological community that constitutes a continuation of food energy from one organism to another as each consumes a lower member and in turn is preyed upon by a higher member.
Trophic Level: A group of organisms that occupy the same position in a food chain.
Food Web: A complex of interrelated food chains in an ecological community
Ecological pyramid: A pyramid-shaped diagram representing quantitatively the numbers of organisms, energy relationships, and biomass of an ecosystem; numbers are high for the lowest trophic levels (plants) and low for the highest trophic level (carnivores).
Biomass: The total mass of living matter within a given unit of environmental area
Biogeochemical Cycle: The chemical interactions that exist between the atmosphere, hydrosphere, lithosphere, and biosphere.
Water Cycle: The cycle of evaporation and condensation that controls the distribution of the earth’s water as it evaporates from bodies of water, condenses, precipitates, and returns to those bodies of water. Also called hydrologic cycle.
Carbon Cycle: The combined processes, including photosynthesis, decomposition, and respiration, by which carbon as a component of various compounds cycles between its major reservoirs-the atmosphere, oceans, and living organisms.
Nitrogen Cycle: A chain of thermonuclear reactions in which nitrogen isotopes are formed in intermediate stages and carbon acts essentially as a catalyst to convert four hydrogen atoms into one helium atom with the emission of two positrons. The entire sequence is thought to generate significant amounts of energy in the sun and certain other stars
Limiting Factors: The success of an organism is limited by the presence or absence of the factors necessary for survival. Often growth of a population is limited by an apparently minor factor in the environment, such as the presence of trace elements in the soil.
Tolerance Range: each ecosystems population’s ability to adjust to variations in its physical and chemical environment
Carrying Capacity: The maximum number of individuals that a given environment can support without detrimental effects
Biome: A major regional or global biotic community, such as a grassland or desert, characterized chiefly by the dominant forms of plant life and the prevailing climate.
Succession: The act or process of following in order or sequence.
Biodiversity: The variability among living organisms on the earth, including the variability within and between species and within and between ecosystems.
Invasive Species: Any species that has been introduced to an environment where it is not native, and that has since become a nuisance through rapid spread and increase in numbers, often to the detriment of native species.
Pollution: The act or process of polluting or the state of being polluted, especially the contamination of soil, water, or the atmosphere by the discharge of harmful substances
Monoculture: A single, homogeneous culture without diversity or dissension.
Pest: An injurious plant or animal, especially one harmful to humans.
Leaching: To remove soluble or other constituents from by the action of a percolating liquid.
Pesticide: A chemical used to kill pests, especially insects

Carbon cycle: Ecology The combined processes, including photosynthesis, decomposition, and respiration, by which carbon as a component of various compounds cycles between its major reservoirs—the atmosphere, oceans, and living organisms.
Carrying Capacity: The maximum number of persons or things that a vehicle or a receptacle can carry
Cellular Respiration: The series of metabolic processes by which living cells produce energy through the oxidation of organic substances.
Consumer: An organism that generally obtains food by feeding on other organisms or organic matter
Dependent Variable: A dependent variable is what you measure in the experiment and what is affected during the experiment
Ecological Niche: the status of an organism within its environment and community
ecosystem: An ecological community together with its environment, functioning as a unit

i forgot my biology book at school and i need help with these questions. any answer helps, i prefer complete sentence if you are willing, but if not, thanks anyway. so here are the questions.
1 What is ecology?
2 define: species; population; community; ecosystem; biome; biosphere;
Tell how these are related.
3 How is a habitat different from a niche;
4 What are biotic and abiotic factors?
5 What is the Competitive Exclusion Principle?
6 How is the movement of matter AND energy through an ecosystem different?
7 What are autotrophs? Give examples. What are heterotrophs? Give examples.
8 Name two ways autotrophic organisms can make their own food. How are these different?
9 What is a resource? A food chain? A food web? How are these related?
10 What is an herbivore, carnivore, omnivore, detritivore, decomposer,scavenger?
11 How do they get their energy? Be able to give examples of each of these.
12 What is a trophic level? What percentage of energy is passed on from one trophic level to the next?
13 What is a biogeochemical cycle?.
14 How do (water, carbon, nitrogen, phosphorus) atoms enter and leave the atmosphere, land, water, and cycle through the ecosystem?
15 In which cycle does the atmosphere NOT play a role?
16 Which biomolecules are important to living things and which cycles provide the atoms to build these?
17 What is transpiration? Nitrogen fixation? Denitrification? Evaporation? Condensation? Precipitation?
18 Which organisms play a role in these processes?
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~…
19 NAME the 6 levels or organization that ecologists use
20 What are the ways organisms interact in an ecosystem? Define:(Competition, Predation, Symbiosis)
21 Name the 3 kinds of symbiosis? Identify examples of each?
21 What are some things organisms must compete for?
22 What is a limiting factor? How does it affect a population?
23 What is primary productivity? An algal bloom?
24 What happens when an over abundance of a limiting factor becomes available?
25 How do organisms cooperate? What is predation? What is a predator? Prey?
26 What are the 3 kinds of symbiosis? Be able to identify examples of each?
27. Name the two things that can affect the size of a population
28. What is exponential growth? Under what conditions does it occur in a population?
29. What is logistic growth?
30. Give two examples of density-dependent limiting factors? What does this type of limiting factor
rely on?
31. What is the difference between primary and secondary succession?
32. What kind of growth is represented by a S curve (as opposed to a J curve)
33. Explain the difference between a resource that is renewable and nonrenewable.
you do not have to answer all of them (you’d be AWSOME if you did though(: ) but try to answer one that hasnt been answered yet. THANK YOU!(:

By best I not only mean for their biology or nursing programs but also the overall college atmosphere.
I prefer some thing small town, non religious affiliated, and Research opportunities
