commensalism
What ecological relationship is depicted between Pumba (warthog) and the bugs?
Competition, because pumba is in competition with the bugs for food sources
Mutualistic, because Pumba and the bugs benefit each other
Predator-Prey, because Pumba is a predator that consumes bug as prey
The flock of white seagulls that are fighting over a single food source (Nemo & Dory) depicts which ecological relatioship?
Intraspecies Competition
Mutualism
Parasitism
Commensalism
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 a predator-prey relationship, when the population of the predator increases, the population of the prey will ____________.
Increase
Remain Stable
Decrease
Change unpredictably
A honeybee and flower relationship in which the flower provides nectar for the honey and the honey can help pollinate other flowers is an example of ________________.
Mutualism
Parasitism
Commensalism
Competition
Wasps often lay their eggs just inside the eggs of butterflies. The wasp larva (baby wasps) are able to get lots of nutrients and protection from the butterfly/caterpillar egg while its developing. After the caterpillar is born, the wasps continue lurking in the flesh of the caterpillar, soaking up more nutrients and drinking its blood. The wasp larva must keep its host alive, so it avoids damaging the vital organs.
What type of symbiosis is being described?
predator/prey
competition
commensalism
parasitism

D
When a population grows past the ecosystem's carrying capacity, what happens to the population?
Continues to grow
The population starts to die off to return to carrying capcity
The population will go extinct due to lack of resources
The population grows then finds a new carrying capacity
