Which statement is an example of parasitism?

• Psuedoscorpions hide under beetles’ wings for protection and transport.

• Wasps lay eggs inside hornworms and after the eggs hatch, the wasp larvae feed on the hornworm.

• Lions and hyenas live in a savanna ecosystem and eat the same prey, antelopes.

• Otters contribute to a high level of diversity in their ecosystem because they eat urchins, allowing kelp to grow.

• Ladybugs consume insects such as aphids, mealyworms, and spider mites.

Which of the below is an example of mimicry that enables prey species avoid predation?

• a poisonous species warning others of danger through brightly colored markings

• a harmless organism imitating the look of a harmful organism

• a hard protective shell

• changing their coloration to blend in with their surroundings

 Hermit crabs live in shells made and then abandoned by snails. This relationship neither helps nor harms the snails.

• commensalism
• mutualism

Ostriches and Gazelles feed next to each other.  They both watch for predators and alert each other to danger.  Since the visual abilities of the two species are different, they can each identify threats the other animal would not as readily see.  

• Parasitism
• Commensalism
•  Mutualism 
• Competition.
