Front 1

Ecology

Back 1

The study of organisms in terms of their relationship with their environment.

Hint 1

All together

Front 2

Plant Biology

Back 2

The study of plants, sometimes referred to as Botany

Front 3

Biome

Back 3

A geographic ecosystem characterized by distinctive vegetation that has developed under specific climatic conditions

Hint 3

Tundra, Desert

Front 10

The interior effect

Back 10

As air moves over a landmass, it loses moisture in the form of rain.

Without passing over another large body of water the air becomes a drier and drier.

Many deserts form in the interior of continents

Front 14

The rain shadow effect

Back 14

Moist air is blowing toward a mountain range from an area near water, as air is forced to rise, it cools and drops rain on the Windward side, the dry air heats up as it descends causing intense evaporation on Leeward side.

Hint 14

Sierra Nevada mountains

Front 15

North American desert regions

Back 15

Great Basin

Mojave

Front 16

Community

Back 16

Groups of species interacting together at the same place at the same time

Example: all biotic components in the desert oasis pond

Front 17

Habitat

Back 17

The area or natural environments in which an organism or community normally lives

A habitat is made up of abiotic factors such as moisture, range of temperature, and availability of light, as well as biotic factors such as the availability of food in the presence of predators

Front 20

Species

Back 20

A group of organisms that are similar because they are descended from a common ancestor and can interbreed

Front 21

Species

Back 21

A group of organisms that are similar because they are descended from a common ancestor and can interbreed

Front 22

Evolution

Back 22

Process by which species gradually accumulate differences from their ancestors

Front 23

Evolutionary mechanisms

Back 23

Natural selection

Artificial selection

Chance events

Mutation

Front 24

Adaptation

Back 24

Adaptations are outcomes of evolutionary change. Characteristics that allow an organism to live successfully in their environment.

Physiological: nocturnal, underground living

Structural: spines, camouflage

Front 25

Natural selection

Back 25

Individual organisms with particular characteristics tend to survive and reproduce at a higher rate than other individuals because of those particular characteristics

Example: Birds like green beetles more than orange, so the orange beetle tends to survive and mate

Front 26

Artificial Selection

Back 26

Intentional breeding for certain desirable traits or combination of traits

Example: Modern produce

Pesticide resistant corn

Front 27

Organism

Back 27

Individual example of a species

Front 28

Symbiosis

Back 28

Organisms interact with the other organisms within their habitat in a variety of ways. These interactions can be fleeting or long-lasting and can have both positive or negative implications

Front 29

4 types of symbiosis

Back 29

Mutualism

Commensalism

Predation

Competition

Front 30

Mutualism

Back 30

Any relationship between individual organisms of different species and we're both individuals benefit

Hint 30

Front 31

Mutualism

Back 31

Any relationship between individual organisms of different species and we're both individuals benefit

Hint 31

++

Front 32

Commensalism

Back 32

Describe the relationship between two living organisms where one benefits and the other is not significantly harmed or helped

Hint 32

+0

Front 33

Predation

Back 33

Herbivory: An interaction where any animal consumes a plant. It is the flow of energy through organisms by which one organism gains energy by consuming another organism.

Parasitism: an interaction where one organism uses another organism as a host to provide energy, shelter, or a place to grow and reproduce offspring.

Herbivory: An interaction where any animal consumes a plant. It is the flow of energy through organisms by which one organism gains energy by consuming another organism.

Parasitism: an interaction where one organism uses another organism as a host to provide energy, shelter, or a place to grow and reproduce offspring.

Front 35

Competition

Back 35

A relationship between organisms competing for resources such as food, water, space, shelter, mate, ecological status, etc., where both organisms are taxed. This often occurs when resources become scarce.

Mycorrhizae

Back 41

The relationship between specific fungi and plants that increase the amount of root surface for greater intake of water and nutrients while the plant provides food for the fungi.
