Biomes and natural selection UNIT 1 SEMESER 2

Evolution history is

Change in genetic makeup overtime in a population

Process that change in allele frequencies overtime

Evolution

5 things that happen during natural selection

Variation

Limited resources

Overproduction

Adaptation

Decent with modifications

Natural selection is

The desire traits chosen by nature

Scientists who believe in the Growing method

lamark

Scientists Who believed in the Natural selection adaptation methods

Darwin

What is artificial selection

Human chosen desired trait

What is antibiotic resistance?

Bacteria invading the host cell

What is this?

A diagram for antibiotic resistance

Resistance in bugs

Insecticide and pesticide resistance

What is a biome?

Defines as Large geographical areas with distinct plant and animal groups adopted to that ecosystem

What does each biome represent?

Own set of evolutionary challenges

In order for organisms to survive what would they do?

Adaptions to the unique challenges of each biome

Biotic vs abiotic components

Factors that are living components of an ecosystem

Factors are the non-living physical and chemical elements

Examples of biotic and abiotic components

Plants, animas, bacteria

Sunlight,water,soil,temperature

Structural adaption

Camouflage (example)

allows an organism to blend into its surroundings

Coloration

Used as a warning sign

Estimation is a behavior of what

Similar towards hibernation)

Where animals shut down during DRY seasons

3 tropisms

photo, gravi or geo, Thig

What is geotrophism

Growth in response to gravity

Rooting growing downward to find a water source

Rather than the roots shooting up against gravity

What is Thigmotropism

Growth in response to touch

Climbing plants or vines around solid like structures

What is phototrohism

Growth in light production.

A positive way would be the stems and the leaves on plants

a negative way would be the roots growing away from the light and deeper into the soil

What are the 7 Land biomes

Deciduous forest

Grassland (savanna is same thing)

Tundra

Desert

Taiga

Tropical rainforest

Marine

In a deciduous forest what are the animal adaptations compared to a grassland animal adaptations

Deciduous forest

• Migration

• Food storage

• Hibernation

• Camouflage

grassland

• Long limbs

• Grazers

• Hunting in packs

• Camouflage

In a tundra what are the animal adaptations compared to a desert animal adaptations

Tundra

• Bubbler

• Fur insulation (layers)

• Migration

• Hibernation

Desert

• large ears to release heat

• Little urine production

In a Taiga what are the animal adaptations compared to a Tropical rain Forest animal adaptations

Taiga

• Hibernation in winters

• Layers of fur or feathers

tropical rain forest

• Camouflage

• Webbed limbs

• Climbing and living in trees

• Nocturnal animals (avoids heat)

In a marine ecosystem what are the animal adaptations

• Seas and oceans

• Substantial salt content

• Greater bio diversity to fresh water

What is mimicry?

Where an animal acts as another as a defense mechanism like frogs where they turn different colors to look “posionous” to predators

What is imprinting?

Most common behavior in birds after birth go to the first thing they see and follow it

(Ducklings)
