Chapter 3

The Biosphere


What is ecology
What is ECOLOGY?

  • Ecology: the scientific study of interactions among organisms and between organisms and their environment, or surroundings.



Levels of organization review
Levels of Organization Review animals as well as land water and air.

  • Biosphere

  • Biome

  • Ecosystem

  • Community

  • Species


What else is in an ecosystem
What else is in an ECOSYSTEM? animals as well as land water and air.


Biotic factors
BIOTIC Factors animals as well as land water and air.

  • The BIO-logical influences

  • Every living thing that an organism may come into contact with

  • Turtles, deer, and all other animals

  • Ferns, trees and other plant life


Abiotic factors
ABIOTIC Factors animals as well as land water and air.

  • Physical or non-living factors

  • These include things we see and things we don’t

  • Temperature, nutrient availability, wind….


Applying the scientific method
Applying the Scientific Method animals as well as land water and air.

  • How many white tailed deer live with in a 5 mile radius of the high school?

  • What response would be produced in a corn snake population if the amount of mice was reduced in their community?

  • Has continental drift effected the speciation of southern migratory birds?


Do now
DO NOW: animals as well as land water and air.

  • Can you see the energy from the sun? Explain.

  • Get out all supplies you need for class

    • Notebook

    • Highlighter

    • Vocab sheet


Producers
Producers animals as well as land water and air.

  • Make their own food

  • Rely on energy obtained from their environment

    • Sunlight

    • Mineral water

  • Aka AUTOTROPHS

    • Auto: SELF

    • Troph: NUTRITION


Photosynthesis
Photosynthesis animals as well as land water and air.

  • Used by autotrophic organisms

    • Photo- sun

    • Synthesis- combination

  • Light energy is used to power

    chemical reactions that create

    simple sugars

  • Plants, Algae and some bacteria

  • simple sugar


Chemosynthesis
Chemosynthesis animals as well as land water and air.

  • Requires NO sunlight

  • Chemical energy is used to produce simple sugars

  • Energy comes from chemical bonds such as hydrogen sulfide (sewer gas)


Extremeophylls
Extremeophylls animals as well as land water and air.

  • Main users of chemosynthesis

  • Live in EXTREME environments

    • Volcano Vents

    • Deep inside caves


Consumers
Consumers animals as well as land water and air.

  • Rely on other organisms for energy

    • Must eat (ingest) for energy needs

  • Aka HETEROTROPHS

    • Hetero: another or different

    • Troph: nutrition


Meat or veggies how about both
Meat or Veggies? How about both animals as well as land water and air.

  • Carnivores: eat animals (meat)

  • Herbivores: eat plant life

  • Omnivores: eat both plant and animal life


Scavengers decomposers
Scavengers & Decomposers animals as well as land water and air.

  • Scavengers: feed on dead plants and animals

    • Includes earth worms, mites and snails

  • Decomposers: break

    down organic matter

    • Bacteria and fungi


Red Tailed hawk animals as well as land water and air. FEEDS ON: mole and field mouse

Garden Mole FEEDS ON: worms Damsel fly

Field Mouse FEEDS ON: Grasses and insects

Grass FEEDS ON: uses the SUN for photosynthesis

Damsel fly larva FEEDS ON: other insects

Oak leaves FEEDS ON: uses the SUN for photosynthesis

Squirrel FEEDS ON: Acorns

Worms FEEDS ON: fallen leaves

Do Now:1. Please get ready for class + get out your Macroinvertebrate lab (bug picking)2.Organize the following organisms as,,,


Do now please get ready for class by getting your food chains out

Red Tailed hawk animals as well as land water and air.

Field Mouse

Grass

Do Now:Please “Get ready for class” by getting your food chains out


Do now1
DO NOW: animals as well as land water and air.

  • What would happen if one of the organisms in your food web was removed?


What happens to the sun s energy
What happens to the sun’s energy? animals as well as land water and air.

  • The sun is the greatest source of energy in our universe

  • Photosynthetic autotrophs make the best use of this energy

  • Using light energy to power chemical reactions these producers are the start to almost all FOOD CHAINS on land and at sea.


Food chain
FOOD CHAIN animals as well as land water and air.

  • Represents the passing of energy from one organism to another

  • Starts with producersenergy is transferred as autotrophs are eaten

    • The energy transfer continues as more animals enter the food chain.


In your notebooks
IN YOUR NOTEBOOKS…. animals as well as land water and air.

Discuss how…

BIOTIC vs. ABIOTIC

BIOTIC vs. BIOTIC

ABIOTIC vs. ABIOTIC

…factors affect each other in the movie.


Trophic levels
Trophic Levels animals as well as land water and air.

  • Each link on a food chain is a separate TROPHIC LEVEL

  • Producers are the first trophic level 3

    • Their consumers (herbivores) are in the 2nd trophic level

    • The 3rd trophic level and up consists of omnivores and carnivores

Do Now: animals as well as land water and air. 1. Please get ready for class. (have your owl lab out)2. Who is the most important organism in the food web


Food web
FOOD WEB animals as well as land water and air.

  • A complex feeding relationship between the populations in an ecosystem.

  • All food chains in an ecosystem are linked together by a food web.


Ecological pyramids
Ecological Pyramids animals as well as land water and air.

  • Representation of energy or matter in each trophic level of an ecosystem

  • Moving up trophic levels on a pyramid shows that only part of the energy or biomass is passed on to the next trophic level. Usually 10 %

-10 %

-10%

-10%

100g


Recycling matters
Recycling Matters animals as well as land water and air.

  • Matter is not gained or lost

  • It must be recycled within an ecosystem and between ecosystems

  • Elements, chemical compound (H20) and other forms of matter follow

    • BIOLOGICALCHEMICAL CYCLES
