Marlin and his son, Nemo, are clownfish that live in a sea anemone. Clownfish benefit by receiving protection and shelter from the sea anemone. The clownfish, in return, scares away predators of the sea anemone and provides nutrients for the sea anemone through its excrement (waste). The symbiotic relationship between Nemo and the sea anemone is known as -
parasitism
commensalism
predator-prey
competition
mutualism

In the mid 1900's, the wolves of Yellowstone were deeply affected by humans and their population significantly decreased-- making them endangered, and eventually removing them completely from the Yellowstone ecosystem. The removal of wolves, the top predator, caused what to happen to the biodiversity within Yellowstone?
A trophic cascade affected the entire food web in Yellowstone, causing some organisms to experience decreases, and others to grow rapidly.
Biodiversity increased when the wolves disappeared and more species were able to flourish without the wolves.
A trophic cascade irreversibly ruined the ecosystem in Yellowstone--destroying biodiversity forever.
The biodiversity of the park was not affected when the wolves were removed.
