Daily TAKS Connection:Food 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.

foldable instructions
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”

Foldable Instructions
notes
Notes
  • 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 -> primary consumer -> secondary consumer ->tertiary consumer
notes continued
Notes 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
question 1
Question 1

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

question 2
Question 2

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

question 3
Question 3

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

food chain food pyramid
Food Chain & Food Pyramid
  • 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
foldable activity
Foldable Activity
  • For the food web provided, name the:
    • 3 herbivores
    • 1 omnivore
    • 10 carnivores

Note: omnivores are also herbivores and carnivores

foldable activity10
Foldable Activity
  • 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.

Which organism(s) is/are also a 4th level consumer?

question 4
Question 4

According to this food web, which of these is an omnivore?

a. Caterpillar

b. Ant

c. Deer

d. Bird

decomposers
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

Add decomposers to your food web.

Decomposers
question 5
Question 5

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

abiotic biotic notes
Abiotic & Biotic Notes
  • Classify the following ecosystems factors as either “Biotic” or “Abiotic”
question 6
Question 6

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
