Biotic vs abiotic
Biotic VS. Abiotic

  • The living parts of an ecosystem are called BIOTICfactors

    • Examples: 6 Kingdoms,trees, plants, flowers, insects, animals

Biotic VS. Abiotic

The non-living things in an

ecosystem are called ABIOTIC

factors

Examples : water, rocks, soil, air, temperature, wind, carbon dioxide, nutrients, sunlight.



Alive
Alive?

  • To be considered living, an organism must…

    • Contain all 7 characteristics of life

      • DNA

      • Reproduce

      • Use energy

      • Adapt

      • Respond to Stimuli

      • Made of cells

      • Grow and Develop


Animal Kingdom

* Food – Cannot make their own food.

* Multi-cellular organisms

Reproduction – Asexual and sexual

Examples – Humans, crustaceans, spiders, insects, fish, birds, mammals, sponges, hydras, coral, worms, etc.


Examples of Animals

Sea horse

Sea anemone

butterfly

Great

White

Shark

Poison

Dart

frog

hydra

human


Plant Kingdom

* Food – make their own food by photosynthesis.

*Multi-cellular

Reproduction – Sexually and asexually

Examples – rose, cactus, grass, daisy, ferns, trees



Kingdom Fungi

* Food – do not make their own food. Decomposers

* Unicellular and multicellular.

Reproduction – Sexual and Asexual

Examples – yeast, mushrooms, mold, mildew, athletes foot, ringworm


Examples of Fungi

Athletes Foot

Bread mold

mushroom

yeast

Bread mold magnified

ringworm

Foot Fungus


Kingdom Protists

* Food – Some make their own food (plantlike); others cannot (animal-like).

* Unicellular and Multi-cellular

Reproduction – Asexual & Sexual

Examples – Euglena, paramecium, amoeba, slime mold, volvox, algae,diatoms, giant kelp


Examples of Protists

Paramecium

Algae

Amoeba

Volvox

Stentor

Euglena

Red algae


KINGDOM EUBACTERIA

*Food – Some can make their own food: other cannot.

* Unicellular organisms.

Reproduction – asexual

Roles: decomposers, food makers, help digest food, clean oil spills, makes nitrogen rich soil(helps plants grow), etc.


Examples of Eubacteria

Anthrax

Staph

Bacteria help digest food

Strep

E. Coli

Blue green algae


Kingdom Archaebacteria

This hot, sulfur-rich, acidic pool in Yellowstone National Park is home to species of Archea,  including Sulfolobus.

Some archaens live 1000’s of miles deep in the ocean near superheated volcanic vents.


KINGDOM ARCHAEBACTERIA

* Food- Some cannot make their own food; others do.

* Unicellular organisms

Reproduction – asexual

Three main types – salt loving, heat loving, and methane makers, harsh environments


Let’s Practice

Which kingdom does each organism belong?

Eubacteria

Animal

Protists

protists

plant

Fungus

Eubacteria

Archaebacteria

ABIOTIC FACTORS AND THEIR AFFECTS ON THE ENVIRONMENT

(AN OVERVIEW)


ABIOTIC FACTORS

  • Sunlight

  • Plants need the sunlight to make glucose by photosynthesis.

  • Without plants, the food chain dies.

  • Sunlight produces heat that changes the temperature of the Earths atmosphere and surface.


ABIOTIC FACTORS

  • Water

  • Organisms are mostly made of water. The cytoplasm of cells are mostly water.

  • Plants need water to do photosynthesis.


ABIOTIC FACTORS

Climate

Includes the average temperature and rainfall for a region. All organisms are adapted for the climate they live. Climate determines the different biomes.


ABIOTIC FACTORS

  • Soil

  • Plants need the soil for the

  • nutrients and water it provides. NOT FOOD!!!.

  • Many animals live in the soil.

  • The type of soil in an area determines the types of plants and animals that can live in the area.

  • EX: Venus Flytraps


ABIOTIC FACTORS

Severe Disturbances

1. Fire – Fire can be good or bad. It

destroys habitat and food. Some plants

need a fire for their seeds to germinate.

2.Hurricanes

3. Volcanoes

4. Floods

5. Storms

6. Droughts


ABIOTIC FACTORS

  • Introduced Species

  • Humans sometimes move organisms to a location where they do not belong. Sometimes they die, but often they prosper.

  • If the organism has no predators, then its population will grow. An example of this occurring this the kudzu plant. It was transplanted to American and nothing eats it here. So, it grows out of

  • control.
