Summary

This research examines how microorganisms interact with each other and with plants and animals in nature. These interactions are fundamental to life on Earth and impact everything from soil fertility to human health. The study shows that microbes can form beneficial partnerships that help plants grow better, aid in animal digestion, or protect against diseases. They can also cause diseases when these partnerships break down or when harmful microbes invade. Impacts on everyday life: – The beneficial bacteria in our gut help us digest food and maintain health – Plant-friendly soil microbes help grow better crops for our food – Understanding harmful microbes helps develop better treatments for infections – Beneficial microbes can be used as alternatives to chemical pesticides – Knowledge of microbial interactions helps develop more sustainable agricultural practices

Background

Most ecosystems contain diverse microorganisms that interact with each other and form complex interaction networks. These microorganisms may colonize plants and animals, creating additional layers of interaction complexity. The interactions range from intraspecific to interspecific, and from simple short-term to intricate long-term relationships. These microbial interactions have played a key role in the evolution of plants and animals, often resulting in coevolution. They control microbial community size, activity and diversity patterns, modulate trophic networks and biogeochemical cycles, regulate ecosystem productivity, and influence the ecology and health of plant and animal partners.

Objective

To review and analyze the main types of biotic interactions between microorganisms and their relationships with plants and animals. The study aims to better understand these interactions to develop microbe-based ecological engineering strategies for environmental sustainability and conservation, improve environment-friendly approaches for feed and food production, and address health challenges posed by infectious diseases.

Results

The study found that microbial interactions are fundamental to life and occur at multiple levels, from molecular to ecosystem scales. Key findings include: 1) Microorganisms form complex interaction networks that influence ecosystem functioning, 2) Plant-microbe interactions significantly impact plant growth, development and health, 3) Animal-microbe interactions range from parasitic to mutualistic relationships with important implications for host health and evolution, 4) These interactions have played crucial roles in the evolution of life forms and continue to influence ecosystem processes.

Conclusion

Biotic interactions involving microorganisms are essential for ecosystem functioning and have played a crucial role in evolution. These interactions occur at multiple organizational levels and involve various types of relationships from parasitism to mutualism. Understanding these interactions is vital for developing sustainable agricultural practices, improving human and animal health, and maintaining ecosystem health. The complexity of these interactions requires considering microorganisms in terms of their social networks rather than as isolated entities.
