Algae live inside the body cells of a species of hydra. The hydra uses the products of the alga's
photosynthesis. Ammonia resulting from the hydra's
metabolism is thought to contribute to the algae's
nutrition.
The relationship between the hydra and the alga is
best described as
1) commensalism
3) saprophytism
2) mutualism
4) parasitism
