Question

energy in a food web
part a
what is the major component missing from this food chain in order to see the flow of energy?
a there are no producers
b there should be a higher level consumer
c these fish do not actually live in the same aquatic habitat
d the bird should not be there as it is the only terrestrial organism
part b
if the shrimp at the bottom of this food chain has a total of 10,000 units of energy, how much of that energy will the bird receive?
a 1 unit

Explanation:

Step1: Identify missing component

A food chain needs producers (autotrophs) to capture energy (e.g., sunlight) and start energy flow. The given chain (shrimp → fish → bird) lacks producers.

Step2: Apply 10% energy transfer rule

Energy transfers ~10% between trophic levels. Shrimp (10,000 units) → fish: $10,000 \times 0.1 = 1,000$ units. Fish → bird: $1,000 \times 0.1 = 10$ units. (Note: If PART B options had 10, it's correct; if only 1 is shown, assume typo in option display, but standard calculation gives 10.)

Answer:

PART A: A. there are no producers
PART B: 10 units (standard result; if option A is 1, likely display error)
