symbiotic relationships

A cuckoo may lay its eggs in a warbler’s nest. The cuckoo’s young will displace the warbler’s young and will be raised by the warbler.

• Mutualism

• Commensalism

• Parasitism

Cattle egrets forage (feed) in fields among cattle. The egret gets easy access to flying insects stirred up by the cattle, and the cattle don't care if they are there or not.

• mutualism
• commensalism
• competition
• parasitism

Hermit crabs live in shells that snails don't use anymore. The hermit crab gets a nice free home.  This neither harms nor helps the snails.

• mutualism
• commensalism
• parasitsm
• predation

Ostriches and gazelles eat together.  They both watch for predators and danger.  Since they see things differently, they each can identify threats the other animal may not see.  Both species are benefited.

Some species of barnacles attach themselves to sea turtles or whales. As the whales or sea turtles travel, the barnacles gain access to food in nutrient-rich waters. Their host neither benefits nor is harmed by its riders.

• Mutualism
• Commensalism
• Parasitism

 

The flock of white seagulls that are fighting over a single food source (Nemo & Dory) depicts which ecological relationship?

• Parasitism

• Commensalism

• Mutualism

• Competition

Mistletoe extracts water and nutrients from the spruce tree to the detriment (ill effect) of the spruce. This is an example of which type of symbiosis?

• parasitism

• commensalism

• mutualism

• predation

A symbiotic relationship in which both organisms benefit:

• Competition.
• Mutualism.
• Commensalism.
• Parasitism.

Yucca flowers are pollinated by yucca moths.  The moths lay their eggs in the flowers and the eggs hatch. The larvae eat some of the seeds, and  spread them around.  Both species are benefited.
