Producers-
organisms that make their own food
37
Consumers-
an organism that cannot produce its own food and must eat other plants and or animals to get energy
38
Food chain-
a linear sequence of organisms through which nutrients and energy pass as one organism eats another
39
Food web-
consists of all the food chains in a single ecosystem
40
Ecosystem-
a community of living things plants animals microbes in a particular area.
41
Niche -
the behaviors and physical traits that help an organism reduce competition. The role of the organism and their population that increases survival for themselves and the species as a whole
42
Molecules-
groups of atoms, bonded together that form a comp compound, they have a specific ratio of atoms in their formula macromolecule, a really large molecule made of hundreds of thousands of atoms
43
Organic-
refers to molecules made by living things/organisms organic molecules are based on the element carbon the four groups of macromolecules organic molecules
44
Inorganic-
refers to molecules made by nonliving abiotic processes
45
Monomer -
monomers are the basic units of polymers
46
Polymer-
the long chains monomer that form macromolecules
47
Glucose-
small, monomer, sugars of carbohydrates starch, or cellular polymers Starch polymer carbohydrate made of thousands of glucose, monomers energy stored in plants.
48
Carbohydrate-
micro molecules used for quick energy include simple sugars
49
Fats-
macro mole molecules group use for stored energy include simple oils, and waxes made of fatty acids and glycerol
50
proteins-
macromolecules use group for structures, and enzymes made of amino acid monomer
51
Nucleic acid-
macromolecule group used for genetic information made of nucleotide monomers
52
Digestion-
breaking down of molecules into smaller parts Nutrient absorption process of taking a material and making part of the body
53
Dentition-
the teeth of an animal
54
Metabolic rate-
the speed at which molecules are built up or broken down
55
Ectotherm-
an animal that controls its temperature by using external energy, called cold blooded
56

neutral
61
Electrons-
negative
62
Outer electron-
called valence electrons
63
What is the make up of Carbohydrates? Function? Monomers/Polymers called?
Carbon, hydrogen, oxygen atoms. Their function is the main source of energy. Their monomers are called monosaccharides. Their polymers are called polysaccharides.
64
What is the make up of Lipids?Function? Monomers/Polymers called?
Carbon, hydrogen, and a little oxygen. Their function is used to store, energy waterproofing, and used by cells to create the membrane. They are not soluble and liquids because they are non-polar their monomer are fatty acids their polymer are triglycerides
65
What is the make up of Nucleic Acids?Function? Monomers/Polymers called?
Carbon hydrogen, oxygen nitrogen, and phosphate. The monomers are called nucleotides and their polymers are called. Rebonucleic acid and deoxynucleic acid. They function as a store and transmit genetic information.
66
What is the make up of Proteins? Function? Monomers/Polymers called?
Carbon, hydrogen, oxygen, nitrogen, and sulfur. Their function is to control the rate of reactions and regulate cell processes. They form bones and muscles transport substances in and out of cells and fight disease

recycling of matter
68
Water cycle water moves from the atmosphere to the geosphere. This includes:
condensation, precipitation, transpiration, and evaporation.
69
The carbon cycle carbon enters the atmosphere from:
decomposition, respiration, animal waste products, burning and combustion, and photosynthesis
70
Photosynthesis formula-

two species live in contact
74
parasitism-
one good one bad
75
Commensalism -
one good no difference
76
Mutualism-
both good
77
Growth rate-
how the population size changes
78
Population growth equals:
birth rate - death rate emmigrants - immigrants
79
Exponential growth occurs:
under ideal conditions. The population increases quickly.
80
Logistical growth:
growth, slows, or stops
81
Carrying capacity-
the number and environment can support
82
Limits to growth are density which are dependent factors which include:
competition disease and overcrowding density in independent factors are weather changes
83
Predator prey relationships-
population fluctuates, prey numbers go up predators go up, vice versa
84
Geographic range-
the area where our population lives
85
Density-
the number of individuals in an area
86
Distribution-
is how organisms are spaced they can either be clumped, random or uniform
87

is the study of human populations
88
Age structure diagrams -
compare population at each age group
89
When measuring populations, you can either use:

90
gene-
is a segment of DNA, located on the chromosomes. It carries hereditary instructions from parent to offspring. A gene codes for a protein that leads to characteristics.
91
allele-
is one specific form of a gene, differing from other alleles by one or a few bases only and occupying the same gene locus as other alleles of the gene.
