Answer 1

To answer your questions:

PART A: The major component missing from this food chain in order to see the flow of energy would most likely be A: there are no producers. Producers (like plants or phytoplankton) are essential in a food chain as they convert solar energy into biomass, which is then consumed by primary consumers (like shrimp or fish). Without producers, the flow of energy cannot begin.

PART B: If the shrimp at the bottom of the food chain has a total of 10,000 units of energy, the bird (higher level consumer) would receive a portion of that energy through the consumption of the shrimp. Typically, only about 10% of the energy from one trophic level is transferred to the next in a food chain due to energy loss at each level (such as through metabolic processes). Therefore, if the bird is a tertiary consumer (after the shrimp), it would receive:

10,000 units x 10% = 1,000 units of energy.

So the answer for PART B is C: 1000 units.
