What are the main characteristics of unicellular organisms in terms of maintaining homeostasis?

To maintain homeostasis, unicellular organisms grow, respond to the environment, transform energy, and reproduce.

Give examples of where bacteria (prokaryotes) can be found and their adaptability.

Bacteria live almost everywhere—in the soil, on leaves, in the ocean, in the air, even within the human body. Bacteria, especially prokaryotes, are remarkably adaptable.

How do yeasts contribute to nutrient breakdown and what is their significance?

Yeasts play an important role in breaking down complex nutrients, making them available for other organisms. Yeasts are used in making bread and other foods.

Why is homeostasis crucial for both prokaryotic and eukaryotic unicellular organisms?
