Type of Nutrition in Amoeba and Hydra

Amoeba and Hydra are two different organisms that have distinct ways of obtaining nutrition.

Amoeba Nutrition
Amoeba is a unicellular organism that belongs to the phylum Protozoa. It is a heterotrophic organism that feeds on other organisms. Amoeba obtains nutrition through a process called phagocytosis.

Phagocytosis is the process by which amoeba engulfs its food. It extends its pseudopodia (false feet) around the food particle and draws it into the cell. Once inside the cell, the food particle is enclosed in a food vacuole. The food vacuole then fuses with a lysosome, which contains digestive enzymes. The enzymes break down the food into smaller molecules, which are then absorbed by the cell.

Hydra Nutrition
Hydra is a freshwater organism that belongs to the phylum Cnidaria. It is a carnivorous organism that feeds on small aquatic animals such as crustaceans and other small invertebrates.

Hydra obtains nutrition through a process called extracellular digestion. The tentacles of Hydra are lined with stinging cells called nematocysts, which are used to capture prey. Once the prey is captured, the tentacles bring it to the mouth, where it is ingested.

Once inside the body, the food is broken down by enzymes secreted by the gland cells in the gut. The digested food is then absorbed into the cells lining the gut and distributed throughout the body.

Conclusion
In conclusion, both Amoeba and Hydra are heterotrophic organisms that obtain nutrition from other organisms. However, they have distinct ways of obtaining nutrition. Amoeba uses phagocytosis to engulf and digest its food, while Hydra uses extracellular digestion to break down and absorb its food.
