Question

euglena item set that are very common in ponds and in nutrients and consequently high al characteristics. euglena are able to also get energy from consuming green of a euglena actile which model below best illustrates the process euglena go through during daylight hours? images of chemical reactions involving co₂, h₂o, o₂, c₆h₁₂o₆ and light energy

Explanation:

Step1: Recall Photosynthesis Equation

Photosynthesis uses \( CO_2 \), \( H_2O \), and light energy to produce \( C_6H_{12}O_6 \) and \( O_2 \). The equation is \( 6CO_2 + 6H_2O \xrightarrow{\text{Light}} C_6H_{12}O_6 + 6O_2 \).

Step2: Analyze the First Model

The first model has reactants \( 6CO_2 \) and \( 6H_2O \), light energy, and products \( C_6H_{12}O_6 \) and \( 6O_2 \), matching photosynthesis.

Step3: Analyze the Second Model

The second model has reactants \( 6O_2 \) and \( 6H_2O \), which does not match photosynthesis (needs \( CO_2 \), not \( O_2 \) as a reactant).

Answer:

The top model (with \( CO_2 \), \( H_2O \) as reactants)
