Question

Какова положительная роль бактерий в природе?

Answer 1

Positive roles of bacteria in nature

Bacteria play many important positive roles in nature. Some of the key ways bacteria are beneficial include:

Nutrient cycling - Many bacteria are involved in important nutrient cycles like the nitrogen cycle. Bacteria in the root nodules of legumes like soybeans and peas fix atmospheric nitrogen into a form that plants can use through a symbiotic process Other bacteria break down organic matter and waste, recycling carbon and other nutrients back into soils and ecosystems

Plant growth - Certain bacteria form mutually beneficial relationships with plants and help them grow. For example, Rhizobium bacteria form nodules on legume roots and fix nitrogen that is used by the plant as a nutrient Mycorrhizal fungi also form symbiotic relationships with plant roots to help absorb water and nutrients from soils

Medicine - Some bacteria produce antibiotics that have been crucial for fighting bacterial infections in both humans and livestock. Bacteria also play roles in fermentation processes used to produce foods and drinks like yogurt, cheese, bread, wine and beer. Probiotic bacteria in our guts aid digestion and support overall health.
