Title: Daily TAKS Connection: Food Chains, Food Webs, and Food Pyramids


1
Daily TAKS ConnectionFood Chains, Food Webs,
and Food Pyramids
  • BIO (12) The student knows that interdependence
    and interactions occur within an ecosystem. The
    student is expected to
  • (E) Investigate and explain the interactions in
    an ecosystem including food chains, food webs,
    and food pyramids.

2
Day 1
  • Construct a 3 door foldable Food Chains, Food
    Webs, Food Pyramids
  • Materials
  • 1 sheet paper
  • Scissors
  • Pen
  • Colored pencils/crayons
  • Food web illustration
  • Glue/tape
  • Instructions
  • Hotdog fold a sheet of paper
  • Hamburger fold the paper 2 times to evenly divide
    the paper into thirds
  • Cut along the fold lines from the edge to the
    valley.
  • Label the bottom of the flaps from left to right
    Food Chain, Food Web, and Food Pyramid
  • Paste the picture of a food web provided onto the
    center flap

3
Day 2
  • Under the Food Chain flap, record the
    following
  • route for the transfer of matter and energy
    through an ecosystem
  • arrows ALWAYS point to the organisms receiving
    the energy (food). Example
  • Producer -gt primary consumer -gt secondary
    consumer -gttertiary consumer

4
Day 2 continued.
  • Under the Food Web flap, record the following
  • shows all possible feeding relationships in a
    community at each trophic level.
  • a network of interconnected food chains. The
    arrows ALWAYS point to the organisms receiving
    the energy (food).
  • Under the Food Pyramid flap, record the
    following
  • Shows the relationship between food energy
    available at the trophic levels from bottom to
    top producer, primary consumer, secondary
    consumer, tertiary consumer
  • Less energy available at higher trophic level
    most energy at producer level
  • More pollutants at higher trophic levels

5
Question
  • In a typical forest community, plants are
    producers, rabbits are primary consumers, and
    wolves are secondary consumers. Which diagram
    correctly represents these relationships?

a c
b d
6
Question
  • The difference in the size of each layer of this
    food pyramid is primarily the result of the
    difference in
  • a. food choices of individual niches
  • b. the amount of food energy at each trophic
    level
  • c. oceanic zones of habitat
  • d. the relative heights of the organisms

7
Question
  • Which of these groups of organisms would most
    likely have accumulated the largest concentration
    of a long-lasting chemical pollutant in their
    bodies?
  • a. Phytoplankton
  • b. Lake trout
  • c. Zooplankton
  • d. Gulls

8
Day 3
  • On the flap labeled Food Chain, draw a food
    chain from the food web provided on the center
    flap. Be sure the arrows are pointing in the
    correct direction.
  • On the flap labeled Food Pyramid, draw a food
    pyramid from the food web provided, placing the
    organisms at the correct trophic level

9
Day 3
  • For the food web provided, name the
  • 3 producers
  • 3 primary consumers
  • 7 secondary consumers
  • 5 tertiary consumers
  • Note Organisms may appear in more than one
    trophic level.
  • Bonus Which organism(s) is/are also a 4th level
    consumer?

10
Day 4
  • Construct a 3 door foldable Herbivores,
    Omnivores, Carnivores
  • Materials
  • Foldable handout
  • Scissors
  • Pen
  • Colored pencils/crayons
  • Instructions
  • Hotdog fold the handout along the fold line
  • Cut the flap along the dotted lines
  • Color the terms on the flaps, each a different
    color

11
Day 4 notes
  • Under the herbivore flap, record the following
  • Primary consumers only
  • Consume plants (producers)
  • Under the omnivore flap, record the following
  • 2nd level or higher consumers
  • Consume both plants and animals
  • Under the carnivore flap, record the following
  • 2nd level or higher consumers
  • Consume animals

12
Day 5
  • For the food web provided, name the
  • 3 herbivores
  • 1 omnivore
  • 10 carnivores
  • Note omnivores are also herbivores and
    carnivores
  • Record the consumers under the appropriate flap
    of your foldable as examples of herbivores,
    omnivores, and/or carnivores

13
Question
  • According to this food web, which of these is an
    omnivore?
  • a. Caterpillar
  • b. Ant
  • c. Deer
  • d. Bird

14
Day 6
  • Construct a 3 door foldable Parasites,
    Scavengers, Decomposers
  • Materials
  • Foldable handout
  • Scissors
  • Pen
  • Colored pencils/crayons
  • Instructions
  • Hotdog fold the handout along the fold line
  • Cut the flap along the dotted lines
  • Color the terms on the flaps, each a different
    color

15
Day 6 continued
  • Under the parasites flap, record the following
  • animals that live off other organism by harming
    it
  • Under the scavengers flap, record the following
  • animals that eat dead animal carcasses
  • Under the decomposers flap, record the following
  • mainly bacteria and fungi that break down and
    obtain energy from dead organic matter
  • essential to the environment
  • recycle nutrients
  • fix unusable nitrogen gas into a usable form
    which will be picked up by plants

16
Question
  • The picture shows a piece of rotting wood. Which
    of these does the picture demonstrate?
  • a. Photosynthesis occurring
  • b. Decomposers growing
  • c. Wood regenerating
  • d. Genes transforming

17
Day 7
  • Construct a 2 door foldable Biotic vs, Abiotic
    Factors
  • Materials
  • 1 sheet paper
  • Scissors
  • Pen
  • Colored pencils/crayons
  • Instructions
  • Hamburger fold handout along fold line
  • Cut foldable along dashed line

18
Day 7 continued
  • Classify the following ecosystems factors as
    either Biotic or Abiotic

Soil Producers Light Primary Consumers
Secondary consumers Air Rainfall Water
  • Record the factors under the appropriate flap of
    your foldable

19
Question
  • The table lists four groups of factors found in a
    particular ecosystem. Which group consists of
    only abiotic factors?
  • a. Group 1
  • b. Group 2
  • c. Group 3
  • d. Group 4
