Question

The introduction of which factor would least affect the biodiversity of an ecosystem?

A. A new disease
B. A native species
c. An invasive species
D. A human population

Answer 1

B. Native species.

Step-by-step explanation:

Being a Native species (meaning the species belongs in that ecosystem), they would have almost no affect on the biodiversity of that ecosystem. Human population, invasive species (species that DO NOT belong in an ecosystem), or a new disease could be catastrophic to the biodiversity of an ecosystem.

Answer 2

Native species

Step-by-step explanation:

New diseases could cause widespread illness and even death that could drastically affect trout population. Invasive species are unnatural towards an ecosystem because predators aren't adapted to hunt feral hogs. Human population causes habitat destruction and hunting of large megafauna like buffalo and elk.
