Humans release carbon dioxide that plants need; plants provide oxygen that humans need.

Tapeworms enter a human’s intestines through contaminated water and steal nutrients from the human.

Remora sharks attach themselves to whales by way of an adhesive disk on their dorsal surface. They then feed on the scraps from the whale’s meals.

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.)
