icture a bobcat sneaking up on a snowshoe hare, abarred owl flying silently through the woods, or a garter
snake opening its jawsto strike a mouse. Allof these animals arepredators. Theycatch, kill and eatother animals as prey.
But many animalsyou might not thinkof as predators alsocatch and eat otheranimals. A robin onyour lawn searching for worms. Or a dragonfly darting overthe water gathering mosquitoes.
Some predators, such as bobcats, red-tailed hawks andweasels, eat only meat. But others such
as raccoons, bears and foxes, arepart time predators. These
animals catch and eat prey when theycan, but they also eat a lot of berries, leaves, nuts and otherplant parts.
Some predators play a double role. A frog preys oninsects, but it can easily become a meal for a snake or great
blue heron.Top predators often come to mind first. These
include wolves, big cats and birds of prey. Most arestrict meat-eaters, are relatively large and usuallyaren’t preyed upon by other animals. They tend toneed lots of space.

vegetables in one place, it’s difficult to rememberthat we are all part of a food chain.
Imagine a chain, such as a necklace, braceletor bike chain. Think of how this chain is madeup of many links, each connected to the next inline. This is how a food chain works. Sunlightgives energy to plants so they can grow. Smallanimals, such as rabbits, eat some of the plants.
Pick an animal symbol on the right. Draw a line between that animal and something that animal might eat,or to an animal that might eat it. Make as many connections as you can think of, creating a food chain.
What did you have for dinner last night? Or,for breakfast and lunch today?
Nothing beats cereal and juice to getgoing in the morning. Pizza, tacos and ham-burgers are other favorites. With moderngrocery stores that offer meat, fruit and

CARNIVORS eat mainly animals.
OMNIVORS eat plants and animals.
HERBIVORS eat mainly plants.
PLANTS need the sun, earth, water and air to make food.

A predator, such as a red-tailed hawk, might killone of the rabbits and eat it. When the hawk dies,tiny organisms turn its body into soil. The soilprovides nutrients that plants need to grow, andthe food chain begins again.
Predators are an important link in the foodchain. What happens to a food chain when preda-tors are removed? Researchers are still searching

for answers. A lot seems to depend on the type ofcommunity and the predators involved. In someareas, the loss of predators has resulted in apopulation explosion of prey animals. Too manyprey can damage a habitat and throw the wholefood chain out of whack, and animals may end upstarving or dying of disease.
