OWL
Definition: a nocturnal bird of prey with large forward-facing eyes surrounded by facial disks, a hooked beak, and typically a loud call
Personal Application:
Name a movie with an Owl

• Owls can be seen in several Disney movies such as Winnie the Pooh, Sword and Stone, legends of the guardians, and Bambi

Owl Pellet
Definition: Personal Application: the mass of undigested parts of a bird's food that some bird species occasionally regurgitate
Although owls cough feathers, hair, and bones of their prey, they still go through the process of digestion and poop similar to other animals.

Definition
Rodent: a gnawing mammal of an order that includes rats, mice, squirrels, hamsters, porcupines, and their relatives, distinguished by strong constantly growing incisors and no canine teeth
Personal Association or
Characteristic
Rodents constitute the largest order of mammals

Word proventriculus
Definition
Proventriculous: This device stores the pellet before it is disgorged
Personal Association or
Characteristic
Sometimes the owl will hole the pellet in the proventriculous 20 hours before disgorging it
Since the pellet in this device partially blocks the digestive system the pellet must be expelled before eating again

Definition Personal Association or
Characteristic
Gizzard: an organ that uses digestive fluids and bits of sand and gravel to grind and dissolve all of the usable tissue from the prey
Humans have a stomach and small intestine that does a similar function, but does not regurgitate food. Rather food passes through the rest of the digestive tract.

• With the given creature describe the following factors in your learning journals

• Choose a creature describe the following factors in your learning journals
• Predator or Prey
• Defense Mechanisms
• Adaptations
• Draw a picture as a model with labels

• What’s going to happen tomorrow?

This is what happens between prey and predators (or producers and consumers)

Create a graph with two organisms showing carrying capacity

• What happens to the prey when the predators increase?/ decrease?
• What happens to the predators when the prey increases?/ decreases?
• What is the relationship between predator and prey? Do they need each other to survive?
