<h3>Global travel and spread of certain species</h3>
Explanation:
Many pathogenic species of bacteria, virus, and other microbes are more prevalent in developing or tropical countries rather than in developed countries.
When an individual’s immune system is weak they become more susceptible to get infected and become carriers of that particular species.
The species grows, develops, and multiplies in the host’s body and when the traveler travels to his/her home country or any other place he/she can transmit the disease to others and again the species grows in numbers. Higher the rate of spread of infection higher is the increase in species.
A food chain is a linear representation of the energy going through organisms while a food web shows multiple connections between the organisms.
A uniform region occupies an area based on a homogeneous characteristic is a true statement. Regions can also be based on ecological features and as well as the location of it region itself.
