Given a scientific passage and an answer, generate a question for the given answer.

Q: Passage: Today, scientists think that electrons truly are fundamental particles that cannot be broken down into smaller, simpler particles. They are a type of fundamental particles called leptons. Protons and neutrons, on the other hand, are no longer thought to be fundamental particles. Instead, they are now thought to consist of smaller, simpler particles of matter called quarks. Scientists theorize that leptons and quarks are held together by yet another type of fundamental particles called bosons. All three types of fundamental particlesleptons, quarks, and bosonsare described below. The following Figure below shows the variety of particles of each type. Answer: quarks

A: What can protons and neutrons be broken down into?

A: Modern members of what broad animal group live in many different habitats and are found on every continent except antarctica?

Q: Passage: A lichen is a mutualistic relationship between a fungus and a photosynthetic organism. The other organism is usually a cyanobacterium or green alga. The fungus grows around the bacterial or algal cells. The fungus benefits from the constant supply of food produced by the photosynthesizer. The photosynthesizer benefits from the water and nutrients absorbed by the fungus. Figure below shows lichen growing on a rock. Answer: the photosynthesizer

A:
The fungus benefits from the constant supply of food produced by what?
