Answer:
Yersinia pestis is the causative agent of plague
Explanation:
Rodents, such as rats, carry the disease. It is spread by their fleas.
Answer:
Results in biodiversity loss due to the proliferated growth of prey that feeds on smaller species
Please find the explanation below
Explanation:
In an ecosystem, organisms feed on one another to obtain energy. In this process organisms called CONSUMERS kill and feed on one another in a process called PREDATION. Top predators are those consumers that are found at the peak of the food chain.
A reduction in the number of top predators/tertiary consumers in an ecosystem means that the secondary consumers they feed on (prey) will grow and reproduce beyond control, hence, causing them to pose serious threat to the population of smaller species below them in the food chain.
Therefore, a decrease/decline in a top predator will impact biodiversity by causing it's loss, as organisms in lower level of the food chain will drastically diminish.
