the range of difference in a characteristic of a habitat that an organism can tolerate
Photic Zone
the upper layers of the water in which light can penetrate
Aphotic Zone
the lower layers of water in which light can’t penetrate
Succession
the gradual and orderly process of change in an ecosystem brought by the replacement of one community by another until stability is established
Pioneer Species
the organisms that are first to show up in an area during primary succession
Biodiversity
the diversity of species within an ecosystem
Habitat Fragmentation
breaking large areas of habitat into smaller ones
Native Species
species that has always been in that area or ecosystem
Exotic Species
Species that has recently been introduced to a new area in which they weren’t originally
Plankton
floating and weakly mobile plants and animals in the ocean
Biotic Factors
all living organisms found in an environment
Abiotic Factors
all nonliving parts of an environment
Ecosystem
system of interactions between living organisms and their environment
Niche
the status of an organism in its community and environment
Habitat
the place an species naturally live and grow
Community
a group of organisms that depend on each other and inhabit the same region and interact with each other
Species
a group of organisms that have a unique set of characteristics
Organism
a living thing that has the ability to act or function independently
Population
a group of organisms of the same species that living in a given area
Predator-Prey Relationship
the relationship between a organism that feeds on another organism
Parasite-Host Relationship
when one organism lives off of another that doesn’t benefit
Food Chains
1st Trophic Level-Producers-autotrophs-most energy, 2nd Trophic Level-Herbivores-1st Order Heterotrophs-Primary Consumer-Only Eat Autotrophs, 3rd Trophic Level-Primary Carnivores-2nd Orders Heterotrophs-Secondary Consumer-Eat Herbivores, 4th Trophic Level-Secondary Carnivores-3rd Order Heterotrophs-Tertiary Consumer
Edge Effect
the increased richness of type organisms resulting from the mixing of the two communities where they join
Primary Succession
the natural development of vegetation and soil in an area where there was none previously
Secondary Succession
succession in an area that was previously occupied by living organisms, but has recently undergone a severe disturbance
Intertidal Zones
where air, earth, and land interact, zone between high and low tide where an abundance of marine life grows
Symbiosis
organisms of different species living together in a close, permanent environment
Mutualism
Both species benefit from the relationship
Parasitism
One species benefits from the relationship at the expense of the other species
Commensalism
One species benefits and the other is neither benefitted or harmed by the relationship
Density Independent Factors
environmental factors that limit populations by unpredictable events
Density Dependent Factors
environmental factors that limit populations by events that spread from person to person, sickness
Carrying Capacity
the number of organisms of one species that an environment can support
Reintroduction Programs
when a population starts to disappear, they raise the animal in captivity and then reintroduce the animal to its original habitat
Habitat Corridors
strips of habitat that connect other parts of preserved habitats
Structure of an Atom
made up of protons, neutrons, and electrons, has the same number of protons and electrons, the number of protons and electrons in the nucleus determine the atomic mass
Covalent Bonding
the sharing of electrons between two or more atoms
Ionic Bonding
when one atom gives up an electron to another
Carbs, Lipids, and Proteins
Carbon, Hydrogen, and Oxygen
Atom
the smallest part of an element
Ions
charged particle
Compounds
two different elements combined together
Molecules
two or more elements combined together
Isomers
chemical compound that has the same number and kinds of atoms as another, but different structural arrangement
Isotope
two atoms of the same element but one has a greater atomic mass
pH
0-Acid, 14-Base, 7-Neutral
Dehydration Synthesis
when a chemical reaction occurs, water is lost during the process of the reaction
Hydrolysis Reaction
during a chemical reaction, water is gained, water introduced to a polymer

catalyst that speeds up a chemical reaction that would normally happen more slowly
Enzyme
catalyst that speeds up a chemical reaction that would normally happen more slowly

process of reaction that are at equal rates, continuous, and create no change
Concentration Gradient
the difference in concentration on opposite sides of the plasma membrane
