These are examples of types of symbiotic relationships:
- Humans ↔ Plants: mutualism — both benefit (humans supply CO2; plants produce O2 and often food).
- Tapeworms → Humans: parasitism — the tapeworm benefits at the host’s expense by stealing nutrients.
- Remora → Whale: commensalism (generally) — the remora benefits (transport and food scraps); the whale is usually neither helped nor significantly harmed. (In some cases remoras may clean parasites, making the relationship closer to mutualism.)
