No, Daphnia can not eat Hydra, Because the Hydra has tentacles to capture the Daphnia and eat it. The Daphnia therefore can not get free which means the Hydra can eat the Daphnia. The Hydra therefore has more force and can eat the Daphnia. Your answer is NO.
Everything needs some sort of nutrients to live. Fungi get their nutrients from photosynthesis, plants do the same and obtain it from the roots, animals obtain their nutrients from eating plants, and other animals.
All organisms need nutrients.
Mushrooms get their nutrients by decomposing organic matter.

Unicellular organisms obtain nutrients by absorbing them.
The scientific name for daphnia is Daphnia pulex. Daphnia are small, planktonic crustaceans commonly used in scientific research as a model organism due to their transparent bodies and ease of cultivation in the laboratory.
