Question

case study
interpreting the food web
what information can you get from your food web?
using the food web you constructed, you
should be able to make observations about
the eating habits of the animals in your case
study.
match the role of each of the
following organisms. (click on each

\t\t\ttype of organism
\t\t\tnutrient source
\t\t\ttype of consumer

Explanation:

To solve this, we analyze each organism:

Lodgepole Pine

• Type of Organism: Producer (plants make their own food via photosynthesis).
• Nutrient Source: Sunlight, water, carbon dioxide (uses these to photosynthesize).
• Type of Consumer: Not a consumer (producers don’t consume; they produce energy).

Red Squirrel

• Type of Organism: Consumer (eats other organisms for energy).
• Nutrient Source: Lodgepole Pine (eats pine seeds/cones) or other plant/animal matter.
• Type of Consumer: Herbivore (primarily eats plants like pine seeds) or omnivore (if it eats insects too, but likely herbivore here).

Crossbill

• Type of Organism: Consumer (eats pine seeds from Lodgepole Pine).
• Nutrient Source: Lodgepole Pine (eats pine seeds).
• Type of Consumer: Herbivore (feeds on plant material, specifically pine seeds).

For the dropdowns (matching roles):

• Lodgepole Pine: Type of Organism = Producer; Nutrient Source = Sunlight/Water/CO₂; Type of Consumer = N/A (or “Producer” as it’s not a consumer).
• Red Squirrel: Type of Organism = Consumer; Nutrient Source = Lodgepole Pine (or plant matter); Type of Consumer = Herbivore (or Omnivore, but likely Herbivore here).
• Crossbill: Type of Organism = Consumer; Nutrient Source = Lodgepole Pine; Type of Consumer = Herbivore.

(Note: The exact dropdown options aren’t visible, but this is the logical matching based on food web ecology. Producers make food, consumers eat producers/other consumers; herbivores eat plants.)
