Question

(a) the alaskan marine food web is a complex network of interconnect alaskan arctic and subarctic waters. it is characterized by a diverse from microscopic phytoplankton to apex predators like orcas. phytopl ice algae, form the base of the food web, providing energy for zoopl are consumed by insects and young salmon.
part a
drag and drop a molecule into each box in the equation to show the chemica phytoplankton uses to make food. each chemical symbol may be used once
6 + 6 → + 6
drag & drop the answer
h₂co₃ c₆h₁₂o₆ h₂o co₂ o₂
note: use ctrl+d to drag the option via keyboard
(b) part b
identify the source that provides energy for the chemical reaction in part a to occur.
enter your answer in the space provided.

Explanation:

Step1: Recall photosynthesis equation

Phytoplankton uses photosynthesis: $6CO_2 + 6H_2O
ightarrow C_6H_{12}O_6 + 6O_2$

Step2: Match reactants and products

First box: $CO_2$; Second box: $H_2O$; Third box: $C_6H_{12}O_6$; Fourth box: $O_2$

Step3: Identify energy source

Photosynthesis requires light energy from the Sun.

Answer:

Part A: $6CO_2 + 6H_2O
ightarrow C_6H_{12}O_6 + 6O_2$
Part B: The Sun (or sunlight)
