The incorrect statement is (b) “Green plants get their food from organic compounds”.
Explanation: Green plants are producers, meaning they create their own food through photosynthesis, using inorganic compounds like carbon dioxide and water to synthesize organic compounds like glucose. Therefore, option (b) is incorrect because green plants do not get their food from pre-existing organic compounds, they actually manufacture them.
Why the other options are correct:
(a) All green plants and blue green algae are producers:
This is true. Green plants and blue-green algae (also known as cyanobacteria) are considered producers because they can create their own food through photosynthesis.
(c) Producers prepare their own food from inorganic compounds:
This is also true. Producers use inorganic compounds like carbon dioxide, water, and sunlight to synthesize organic compounds.
(d) Plants convert solar energy into chemical energy:
This is correct. During photosynthesis, plants capture solar energy and use it to convert inorganic compounds into organic compounds, essentially storing chemical energy in the process.
