Where do plants primarily obtain the energy required to live and grow?
A
From oxygen in the air
B
From sunlight through the process of photosynthesis
C
By absorbing nutrients from the soil
D
By consuming other organisms
Verified step by step guidance1
Understand that plants are autotrophs, meaning they produce their own food rather than consuming other organisms.
Recall the process of photosynthesis, where plants convert sunlight into chemical energy stored in glucose molecules.
Recognize that sunlight is the primary energy source for plants, which they capture using chlorophyll in their chloroplasts.
Note that oxygen in the air is not a source of energy for plants; instead, oxygen is a byproduct of photosynthesis.
Clarify that while nutrients from the soil are essential for plant growth, they do not provide energy but rather support metabolic processes and structural development.
