Biology Midterm

Front 1

Ecology

Back 1

The study of how organisms interact with one another and with their environment.

Front 2

Ecosystem

Back 2

Places where organisms interact like deserts, ponds, mountains, oceans, and tropical forests.

Front 3

Biosphere

Back 3

All the ecosystems of the earth-interconnected

Front 4

Florida ecosystems

Back 4

Beaches, alt marshes, fresh water streams, wet prairie, pine forests

Front 5

Populations

Back 5

Members of a single species living together and interbreeding. ex. bullfrogs in a Mississippii pond.

Front 6

Community

Back 6

All the populations living together and interacting.

Front 7

5 types of symbiosis

Back 7

1. Mutualism- Both organisms benefit
2. Commensalism- One species benefits while the other is unaffected
3. Parasite/Host: One species is positively affected while the other is negatively affected
4. Competition: Both species are negatively affected
5. Predator/Pray: One species benefits while the other is negatively affected

Front 8

Ectoparasite

Back 8

Lives on the outside

Front 9

Endoparasite

Back 9

Lives on the inside

Front 10

Ecological Niche

Back 10

It is a unique role that a critter plays in its ecosystem. Address and occupation. It is the sum of all of a species ecological interactions.

Front 11

Food Chains

Back 11

Energy passes through trophic levels. The sun is the energy source for most ecosystems. Only ten percent of the energy moves from one trophic level to another.

Front 12

Tophic Levels

Back 12

1. Sun
2. Autotrophs- They feed themselves and are producers.
3. Heterotroph- primary, secondary, and tertiary consumers

Front 13

Food webs

Back 13

Recognizes organisms feed from a complex menu.

Front 14

Bio geochemical cycles

Back 14

Exchanges of important chemical compounds between critters and the abiotic ecosystem.

Front 15

Ecological succession

Back 15

The changes that occur on a landscape as one community replaces another as the ecosystem matures.

Front 16

Early stages of Ecological succession

Back 16

Low biomass
Low diversity
Higher growth-rate
less nutrient cycling
more autotrophs
less stable

Front 17

Late stages of ecological succession

Back 17

High biomass
High diversity
Low growth-rates
More nutrient cycling
More heterotrophs
More stable

Front 18

Biomes

Back 18

Large geographic areas characterized by similar climates, similar latitudes, and vegetation types.

Front 19

Exponential Growth

Back 19

- Population grows at its biotic potential

Front 20

Logistic growth Curve

Back 20

Actual growth and is constrained by environment conditions

Front 21

Limiting factors that restrict population growth.

Back 21

Density dependent factors- Disease, famine, poor water quality, predation, competition

Density Independent factors- Natural disasters like fire, freeze, and storms

Front 22

Controlled Experiment

Back 22

Control groups: companion experiment without a variable and allows comparison to measure the effect of the variable.

Experiment Variable: Some condition that is tested for its effect- ex. light, temp., drug

Front 23

Metric System

Back 23

International system of measurements and has standardized units.

Front 24

King Henry Died Unusually Drinking Chocolate Milk

Back 24

K= Kilo 1000/1
H= Hecto 100/1
D= Deca 10/1
U= Basic unit like meters, liters, or grams 1/1
D= Deci 1/10
C= Centi 1/100
M= Milli 1/1000

Front 25

Density

Back 25

Is the mass over the volume (m/v) of an object
grams/cm 3 or grams/ml

Front 26

Atoms

Back 26

Building blocks of matter

Front 27

Periodic table

Back 27

Predictable chemical behaviors of elements. Shows an element's atomic number and atomic mass number

Front 28

Ion

Back 28

When the total number of electrons in an atom is different from the number of protons

Front 29

Atomic number

Back 29

The number of protons in an atom

Front 30

Atomic mass number

Back 30

The average number of protons and neutrons in an atomic nucleus

Front 31

Isotopes

Back 31

Most elements have some atoms with different numbers of neutrons

Front 32

Valence Electrons

Back 32

Inner electrons are more stable and have less energy
Outer electrons are less stable and have more energy

Front 33

Covalent bonds

Back 33

2 atoms share unpaired valence electrons. The atom becomes more stable as the valence level satisfies the octet rule

Front 34

Ionic bonds

Back 34

Unstable atom transfers an electron to another atom so that each becomes more stable

Front 35

Solvent

Back 35

A substance tin which another substance is dissolved

Front 36

Solute

Back 36

A substance that is dissolved in the solvent

Front 37

Water as a solvent

Back 37

Water forms hydrogen bonds to polar solutes and puts them in the solution
