Question

pet owners begin to abandon their burmese pythons in the everglades when they become too large for home care. native species of frogs and reptiles decrease with the introduction of the snakes. what does this scenario represent?
a loss in biodiversity due to mutualism
a loss of biodiversity due to an invasive species
a loss of biodiversity due to a catastrophic event
a loss of biodiversity due to a commensalism

for consecutive seasons, farmers have exceeded their pesticide use. how will this affect the community of animals that share their ecosystem?
pesticides will not harm any of the animals that live in the area.
any animal susceptible to pesticides will die or suffer altered reproductive cycles.
most animals will immigrate to avoid pesticide exposure.
any animal exposed to the pesticide will die in the area surrounding the farms.

Explanation:

1. In the first scenario, Burmese pythons are non - native (invasive) species in the Everglades. Their introduction causes a decrease in native frog and reptile species, which is a loss of biodiversity due to an invasive species. Mutualism is a positive interaction between species, a catastrophic event is a sudden and large - scale disaster, and commensalism is a relationship where one species benefits and the other is unaffected, none of which apply here.
2. In the second scenario, pesticides are harmful chemicals. Animals susceptible to them will either die or have their reproductive cycles affected. Pesticides are known to be harmful to many animals, not all animals will be able to migrate to avoid exposure, and not all exposed animals will die immediately.

Answer:

1. B. A loss of biodiversity due to an invasive species
2. B. Any animal susceptible to pesticides will die or suffer altered reproductive cycles.
