Final answer:
Prokaryotes are abundant and diverse due to their adaptability to various conditions and resources. They can be found in almost every environment and play a vital role in nutrient recycling and ecosystem evolution.
Step-by-step explanation:
Prokaryotes are the most abundant and diverse form of life on Earth due to their ability to adapt to a wide range of conditions and resources.
They can be found in almost every environment, including extreme conditions such as boiling springs, frozen environments, and environments without oxygen. This adaptability allows them to outcompete other organisms and thrive in various ecosystems.
Furthermore, prokaryotes play a vital role in nutrient recycling and drive the evolution of new ecosystems through their metabolic versatility and ability to break down complex compounds.
