Question

use the photosynthesis interactive to answer the question. suppose that you conduct an experiment to determine how photosynthetic output, measured in oxygen (o₂) production, changes as you alter photosynthesis, and generate the graph. identify which manipulations to photosynthesis generated the observed changes in o₂ production depicted in the graph.

Explanation:

Photosynthesis is affected by various factors. High CO₂ levels generally enhance photosynthesis and thus increase O₂ production. High O₂ can inhibit photosynthesis through photorespiration. Green light is not well - absorbed by photosynthetic pigments, reducing photosynthesis. High temperatures can denature enzymes involved in photosynthesis, initially increasing and then decreasing photosynthesis depending on the range. Based on the graph showing increased O₂ production compared to normal, high CO₂ is a likely factor as it promotes photosynthesis.

Answer:

high CO₂
