Animal Defense Strategies and Relationships

The video provides a science lesson on interactions among living things, covering topics such as natural selection, adaptation, specialization, competition, predation, defense strategies, and symbiotic relationships. It explains how species adapt to their environments, reduce competition through specialization, and engage in predator-prey dynamics. The video also discusses various animal defense mechanisms and different types of symbiotic relationships, including mutualism, commensalism, and parasitism.

What is the process called where a species becomes better suited to its environment?

• Symbiosis

• Adaptation

• Predation

• Natural Selection

How do warblers in a spruce forest avoid competition for food?

• By sharing the same food source

• By specializing in feeding in different parts of the tree

• By eating different types of food

• By migrating to different areas

In a predator-prey relationship, what happens if the prey population decreases?

• The prey population becomes extinct

• The predator population remains the same

• The predator population decreases

• The predator population increases

Which of the following is an example of a protective covering as a defense strategy?

• A grasshopper with bright colors

• A pangolin rolling into a ball

• A chameleon changing color

• A butterfly with eye-like patterns

What is mimicry in the context of animal defense strategies?

• An animal changing its color to blend in

• An animal pretending to be another species

• An animal using a hard shell for protection

• An animal using bright colors to warn predators

Which defense strategy involves an animal using bright colors to warn predators?

• Warning coloring

• Protective covering

• Mimicry

• Camouflage

What is the main benefit of camouflage for an animal?

• To warn predators

• To mimic other animals

• To hide from predators

• To attract mates

Which type of symbiotic relationship benefits both species involved?

• Predation

• Parasitism

• Mutualism

• Commensalism

In commensalism, what happens to the species that does not benefit?

• It becomes extinct

• It is harmed

• It benefits

• It is unaffected

What is the role of a host in a parasitic relationship?

• To benefit from the parasite

• To provide shelter for the parasite

• To compete with the parasite

• To be harmed by the parasite
