Unit 3 Ecology Honors Biology 1-2

Pitcher plants in the genus Nepenthes produce a nectar that tree shrews find very tasty. The tree shrews perch over the pitcher plant to lick the nectar and often use it as a toilet. The pitcher plants are able to use the nitrogen from the tree shrew's waste. What type of symbiotic relationship do these organisms have?

• Parasitism

• Mutualism

• Commensalism

As a part of the Cordyceps fungus's life cycle, it will infect the neurological systems of insects like ants. Once inside the ant, the fungus controls the ants movements and brings it to an ideal place for the fungus to produce and release its spores to continue its life cycle. The insects do not survive this process. What type of symbiotic relationship do these organisms have?

• Commensalism
  

• Mutualism

• Parasitism

In South America's Amazon Rainforest, there is an interesting relationship between the Colombian Lesserblack Tarantula and the Dotted Humming Frog. The frog will live in the tarantula's burrow with it, hidden away from predators, and eat insects that would normally prey on the tarantula's eggs. What type of symbiotic relationship do these organisms have?

• Parasitism

• Mutualism

• Commensalism

In the tundras of Canada, Scandinavia, and Russia, arctic foxes are closely associated with caribou (reindeer). In the winter, the caribou will dig at the lichen covering the ground which makes up most of their diet. This digging disturbs small mammals sheltering in the ground, allowing the arctic foxes to hunt more efficiently. What type of symbiotic relationship do these organisms have?

• Commensalism

• Mutualism

• Parasitism

Members of meerkat colonies often have lookouts watching for predators. A species of bird called a drongo have learned to mimic the calls of meerkats to alert them of danger. Most of the bird's calls are genuine and the scared meerkats will often drop their insect prey to flee into tunnels, allowing the drongos to swoop in for a meal. In one or two sentences, explain which symbiotic relationship you think these organisms have with each other AND WHY!

• Commensalism

• Mutualism

• Parasitism

What type of symbiosis?  Hummingbirds feed on nectar from flowers.  The flowers are pollinated by hummingbirds as they move from flower to flower.

• commensalism
• mutualism
• parasitism
• predation

• commensalism
• mutualism
• parasitism
• predation

Barnacles are animals that cannot move. In order to get food, they attach to whales and catch any floating plankton in the water. The whale is neither helped nor harmed in the interaction. What type of symbiosis is this?

• Mutualism

• Commensalism

• Parasitism

• Neutralism

If the secondary consumer level has 20,000 kcal available to it, how much energy was captured by the producers during photosynthesis?

• 2 kcal

• 200 kcal

• 200,000 kcal

• 2,000 kcal
