In the mid-1980s, an aggressive strain of algae known as Caulerpa was accidentally introduced into the Mediterranean Sea when a seaside aquarium cleaned out its tanks. The algae contains a toxin that prevents native herbivores form consuming it. Caulerpa quickly spread over the sea floor, crowding out many species including sponges, corals, sea fans, and lobsters.
Which statement explains the most likely impact Caulerpa has had on the biodiversity in the Mediterranean Sea?
The presence of Caulerpa within an ecosystem is an indicator of the ecosystem's health.
The spread of Caulerpa improved the habitat for many species of sea grasses, and increased the biodiversity.
Caulerpa interbred with native species with the same adaptations within the ecosystem.
Caulerpa became dominant within the ecosystem and reduced the biodiversity.

Which statement explains why these fungi are an important part of the biogeochemical system?
Saprophytes perform gas exchange that assist the cellular activities of autotrophs.
Saprophytes extract minerals from living tissue to recycle tehm back into the soil.

Scientists have observed many types of tropical fish moving beyond their traditional ocean ranges into waters that have historically been more temperate. These fish compete for food with native fish, consuming much from the kelp forests and beds of sea grass.
The expansion of the ranges of tropical fish was most likely caused by -
agricultural runoff that contributes to dead zones in the ocean
global droughts that raise the salt concentration of ocean waters
the rising temperatures of ocean waters
acid rain pollution that lowers the pH of ocean waters
