Chompling — Changes in Food Webs Apex Den Vault
Hi!
I'm Chompling.
Welcome to Apex Den Vault!
Will you help me investigate changes in food webs?
The Grumblies have mixed up our clues.
Let's check the evidence!
Food-web changes can affect several organisms.
If a food source declines,
consumers depending on it may have less food.
What may fewer insects mean for insect eaters?
- A. No possible effect
- B. Less of that food
- C. Guaranteed more insects for everyone
The answer is B: Less of that food
Our record shows fewer insects and birds that eat insects and seeds.
Birds may use more seeds,
but we need evidence about seed supply before predicting their population.
That clue helps us make sense of this place.
Alternative foods and other conditions can change the outcome.
A simple web supports a possible effect,
not an exact count of future animals.
Which alternative food is listed for these birds?
- A. Seeds
- B. Only rocks
- C. Only sunlight
The answer is A: Seeds
Alternative foods and other conditions can change the outcome.
A simple web supports a possible effect,
not an exact count of future animals.
Hmm...
how does that connect to our first clue?
Our record shows fewer insects and birds that eat insects and seeds.
Birds may use more seeds,
but we need evidence about seed supply before predicting their population.
What additional evidence would help?
- A. The color of the graph border
- B. Only the birds' names
- C. Available seed supply
The answer is C: Available seed supply
Our record shows fewer insects and birds that eat insects and seeds.
Birds may use more seeds,
but we need evidence about seed supply before predicting their population.
