This type of circuit has only one pathway for current flow, all the loads are on or off together, not independently. It also has the same current throughout the whole circuit, and the voltage is equal of all loads in the circuit.
What is Series?

Some aspects of Biotic and Abiotic factors.
Biotic aspects: - include ALL LIVING things (plants, animals, and microorganisms)
Abiotic aspects: - includes all NON-LIVING components (sunlight, water, minerals, air)

Definition of Lithosphere, Hydrosphere, Atmosphere, Biosphere
Lithosphere= solid portion of the Earth (all land masses)
Hydrosphere= layer of water surrounding the Earth or found on Earth (includes: oceans, lakes, rivers, ponds, groundwater, glaciers)
Atmosphere= layer of gases surrounding Earth
Biosphere= the part of the Earth where living things are found

Definition of non-native and invasive species.
Non-native species: Introduced by humans to ecosystems that they were NOT originally apart of. Can be a major cause of species loss, the new ecosystem could lack population controls, could lack predators could lack diseases. Native species and introduced species compete, where introduced species could out compete the native species.
Invasive species: Are introduced species with growing populations that spread and have a negative effect on their environment.
100
The 2 types of mixtures and their definition.
Homogeneous: A homogeneous mixture is one whose composition is uniform throughout the mixture. E.g. A mixture of white flour and sugar.
Heterogeneous: A heterogeneous mixture is a mixture in which the composition is not uniform throughout the mixture. E.g. A Salad.
200
This type of circuit has more than one pathway for current flow, the loads can be controlled independently. The sum of each branch is the total current throughout the whole circuit, and the voltage is the same in each branch as the total.
What is Parallel?
200
The definition of individual, population, community, ecosystem.
Individual: A single member of a species
Population: All members, numerous individuals of the SAME SPECIES in a given area
Community: A collection of populations of DIFFERENT SPECIES in a given area
Ecosystem: All of the biotic and abiotic factors of a given area
200
The definition of Mutualism, Commensalism, Parasitism.
Mutualism: Two individuals benefit from each other. E.g. Nitrogen-fixing bacteria living in the roots of legume plants, bacteria get sugars from the plants and the plants receive usable nitrogen from the bacteria.
Commensalism: One individual benefits while the other neither benefits nor is harmed. E.g. birds building nests in trees
Parasitism: One individual benefits (parasite) while the other is harmed (host). E.g. Tapeworms in animals, malaria

Explanation of Biodiversity and Species Richness.
Biodiversity is the variety of life in an ecosystem measured by counting the number of species that live there
Species richness is the number of species in an area

The names of these Element Symbols
He, Fe, K, N, O, H, C, Ca, Na
Helium, Iron, Potassium, Nitrogen, Oxygen, Hydrogen, Carbon, Calcium, Sodium

This must be added up to get the total in series, while is equal all throughout in parallel.
What is Potential Difference/ Voltage (V)?
300
The definition for Food Chain and Food Web. Also the description of the "10% rule"
Food Chain: A linear representation of species interactions also shows the flow of energy.
Food Web: A series of interconnected food chains which also shows numerous pathways and feeding relationships.
"10% rule": Each level in an food chain only gives 10% of its energy to the next level.
300
The Definition of the Carbon Cycle. Also a few examples of how Carbon is released into the atmosphere, and how it is used when in the atmosphere.
Carbon Cycle= The series of processes by which carbon compounds are interconverted in the environment, involving the incorporation of carbon dioxide into living tissue by photosynthesis and its return to the atmosphere through cellular respiration, the decay of dead organisms, and the burning of fossil fuels.
Ex of use) During Photosynthesis plants recycle the CO2 into glucose.
Ex if releasing into atmosphere) Deforestation, Burning fossil fuels, cellular respiration.
300
The Definition of the Water Cycle. Also the definitions of Evaporation, Transpiration, Condensation, Precipitation, Percolation.
Water Cycle= The water cycle, is a biogeochemical cycle that involves the continuous movement of water on, above and below the surface of the Earth.
Evaporation= change of state from a liquid to a gas/vapour (requires heat)
Transpiration= water loss or evaporation from plants
Condensation= change of state from a gas/vapour to a liquid (remove heat or let cool)
Precipitation= water falling through the atmosphere as a liquid or solid
Percolation= vertical (downward) movement of water through the soil and rock
300
This is how to calculate the amount of energy used to make electrical energy measure in joules.
P = W/t
Where:
P = power in Watts
W = Work or electrical energy used/needed (J)
t = time (s)
400
This device measures electric current.
What is an ammeter?
400
The definition of producers and consumers as well as their other name.
Producer: Makes its own food. ( Ex. Plants) A.K.A Autotrophs.
Consumer: Consumes other organisms for food. (Ex. Wolf) A.K.A Heterotrophs.
400
The Definition of the Nitrogen Cycle. Also the use of nitrogen for us, as well as the 2 methods of converting N2 into Nitrate NO3-
Nitrogen Cycle= The series of processes by which nitrogen and its compounds are interconverted in the environment and in living organisms, including nitrogen fixation and decomposition.
Methods of converting N2 - NO3-
Lightning has the ability to FIX oxygen to nitrogen gas to form nitrate. Rain dissolves the nitrate and carries it into the soil, producers readily absorb the nitrate through the roots. This nitrate is then used to build proteins.
- Nitrogen-Fixing Bacteria. Bacteria provide a majority of the nitrogen to an ecosystem, some are found living in the soil (free-living). Some are found of living in the roots of plants inside a root NODULE.
400
Definition of Competition, and the difference between Intraspecific Competition and Interspecific Competition.
Competition: Two individuals vie for the same resource, they can compete with own species or with other species
Intraspecific: Members of the same species compete for the same resources.
Interspecific: Members of different species compete for the same resources.

These are types of electrical power generation, and their definitions.
Water: Hydropower, or hydroelectric power, is a renewable source of energy that generates power by using a dam or diversion structure to alter the natural flow of a river or other body of water.
Nuclear: Nuclear power reactors use heat produced during atomic fission to boil water and produce pressurized steam. The steam is routed through the reactor steam system to spin large turbines blades that drive magnetic generators to produce electricity.
Thermoelectric: Thermoelectric materials generate power directly from the heat by converting temperature differences into electric voltage.
Wind: A wind turbine is a device that converts the kinetic energy of wind into electrical energy
Solar: Solar energy is radiant light and heat from the Sun that is harnessed using a range of technologies such as solar power to generate electricity, solar thermal energy, and solar architecture
Tidal: Tidal power is produced by the surge of ocean waters during the rise and fall of tides. Tidal energy is a renewable source of energy.
Geothermal: Geothermal energy is thermal energy extracted from the Earth's crust. It combines energy from the formation of the planet and from radioactive decay.

Cellular Respiration:
Word Equation: Oxygen + Glucose => Water + Carbon Dioxide
Chemical Equation: O2 + C6H12O6 => H2O + CO2
Photosynthesis:
Word Equation: Water + Carbon Dioxide => Oxygen + Glucose
Chemical Equation: H2O + CO2 => O2 + C6H12O6

- Grass = producer
-Grasshopper, Mouse, Owl = Consumer
-Herbivore= Grasshopper
- Carnivore = Mouse, Owl
-No omnivores
-Owl = Apex Predator

Explanation of Pollution.
When released into the environment, toxic materials are called pollution. Polluting materials can; have a specific purpose (pesticides and fertilizers), be by-products of our consumer society (automobile exhaust and product packaging). Even natural, biodegradable products can pollute when put into the environment in high concentration

Explanation of Bioaccumulation Biomagnification.
Bioaccumulation Biomagnification the gradual accumulation or increase of substances, such as pesticides or other chemicals, in an organism. Bioaccumulation occurs when an organism absorbs a substance faster than it can be lost or eliminated by excretion.
