A true-or-false question is useful only if you can explain your choice. Create practice from your PDF, then correct each false statement in your own words instead of remembering which button you pressed.

In a food chain, energy stored in biomass can be transferred when one organism consumes another. Not all of that energy becomes biomass in the consumer: some material is not eaten or assimilated, and respiration transfers energy to other forms, including heat. Energy is conserved, but it flows through ecosystems rather than being recycled in the same way as atoms in matter. Photosynthesis transfers light energy into chemical stores; it does not create energy from nothing. A food-chain arrow indicates the direction of transfer from a food source to a consumer.
The passage and worked output below are original editorial teaching examples. They show a valid transformation of this passage, not an AI run we performed or a guarantee of the output from your upload. The downloadable PDF contains the same input passage.
Check an overstatement
All energy stored in an organism’s biomass becomes biomass in the next consumer.
Reveal answer and explanation
False.
The passage describes uneaten or unassimilated material and transfers through respiration. Replace “all” with a qualified explanation of what is transferred.
Distinguish transfer from creation
Photosynthesis creates energy from nothing.
Reveal answer and explanation
False.
It transfers light energy into chemical stores. Energy conservation is not suspended by a biological process.
Preserve the relationship
The passage distinguishes energy flow from the recycling of atoms in matter.
Reveal answer and explanation
True.
It describes different roles: energy is transferred through the system, while atoms can be reused in material cycles.

Choose Games before uploading. The landing page does not preselect a subject or question type.
Upload one PDF, TXT or Markdown file, up to 10 MB. Start with a manageable lesson and keep the definitions, examples and conditions that explain it.
Try the formats available in your set. After answering, check the explanation in your source rather than learning only which option was marked correct.
Use a complete PDF claim
+
Keep the heading, condition and surrounding sentence with a statement. An extracted line beginning with “it” may lose its subject when the preceding paragraph is missing. Check multi-column reading order, captions and exceptions before treating a generated true/false statement as a faithful version of the source.
Correct the false part precisely
+
Identify the word or relationship that makes a statement false. A single absolute such as “all” can change a qualified claim. Rewrite the whole sentence correctly rather than only replacing the answer label. Avoid combining two independent assertions when they could have different truth values.
Find True/False in the generated set
+
Choose Games before uploading. Afterwards, True/False is available when the set contains valid statements of that type. The current interface does not offer a true/false-only upload setting. A PDF can produce other formats, too; the examples here do not guarantee the mix for your document.
Supported inputs and result limitations
Upload a PDF, TXT or Markdown file up to 10 MB. A scan or image-heavy page may be difficult to read, and extraction can fail. Save other material in a supported file first: this workflow does not directly import Word, PowerPoint, URLs or pasted text, or add a subject-specific generator setting.
Before studying, check the answers in your original document and look for missing topics. Generated cards and questions can be wrong or unclear. Their number and available formats may differ from these examples, and your usual account and plan limits still apply.
Review answers in the actual study view
In True/False, choose True or False and press Lock it in! The result gives feedback and shows the correct truth value after a mistake. Read the explanation and source context when provided, then check the exact claim in the PDF.
