Answer :
Answer:
This is an example of a mutualistic relationship between humans and the bacteria in their digestive tract. In a mutualistic relationship, both organisms benefit from the association. In this case, humans benefit from the bacteria aiding in the digestion of food, while the bacteria benefit from a nutrient-rich environment provided by the undigested food in the digestive tract.
Explanation:
In a mutualistic relationship, two different species interact in a way that is mutually beneficial for both parties involved. In the context of the relationship between humans and the bacteria in their digestive tract:
1. **Humans benefit**: The bacteria in the digestive tract aid in the digestion of food, breaking down complex molecules into simpler forms that can be absorbed by the human body. This process helps humans extract nutrients from their food and facilitates the absorption of essential vitamins, minerals, and other nutrients necessary for health and well-being.
2. **Bacteria benefit**: The undigested food components that pass through the digestive tract provide a nutrient-rich environment for the bacteria to thrive. The bacteria can metabolize these substrates, obtaining energy and nutrients for their own growth and survival. In turn, the bacteria help maintain a healthy balance in the gut microbiome, supporting overall digestive function and contributing to the well-being of the host.
This mutualistic relationship illustrates how humans and the bacteria in their digestive tract have coevolved to support each other's nutritional needs and overall health. The symbiotic interaction between the two partners highlights the importance of a balanced gut microbiome in promoting digestion, nutrient absorption, and overall well-being in humans.
This an example of mutualism. Both benefit from their relationship and nobody gets harmed.
