Question

model 1

1. label the boxes representing what is needed by the plant to survive and what is created by the plant.
2. what does the direction of the arrow represent in the model?

Explanation:

Question 2

In plant process models (like photosynthesis/respiration), arrows show the flow of substances (e.g., gases, nutrients, energy). For a plant, arrows might represent movement of inputs (e.g., CO₂, H₂O, light) into the plant and outputs (e.g., O₂, glucose) out, or transport within (e.g., water from roots to leaves, sugars from leaves to roots). The direction indicates the pathway of substance transfer (e.g., uptake, production, transport, release).

Answer:

The direction of the arrow represents the flow (movement/transfer) of substances (e.g., reactants, products, nutrients, energy) involved in the plant's processes (like photosynthesis, respiration, or nutrient uptake/transport), showing the pathway of how materials enter, move within, or exit the plant.
