Hint 1

Example: what animals do during winter

Front 2

FOOD WEB

Back 2

a pattern of combined food chains

Hint 2

has lots of animals

Front 3

CARNIVORES

Hint 3

Example: Lion

Front 4

BEHAVIOR

Back 4

the way an animal acts

Hint 4

Front 5

INSTINCT

Back 5

an animal is born knowing this behavior

Back 6

is the path along which energy is passed from one organism to another

Hint 6

first is eaten by the second, the second iseaten by the third and so on

Front 7

Back 7

a change in an animal's physical makeup that makes an organism better able to survive in its environment

Hint 7

example: thick fur

Front 8

CAMOUFLAGE

Hint 9

Which one is the prey?

Front 10

PREDATOR

Back 10

a carnivore that haunts and kills other animals for food and has adaptations that help it capture the animals it preys upon

Hint 10

Which one is the predator?

Front 11

DECOMPOSER

Back 11

an organism that obtains nutrients by consuming and decaying organic matter

Hint 11

Front 12

INCOMPLETE METAMORPHOSIS

Back 12

metamorphosis where an animal looks the same as an adult as they did as a baby. They simply grow larger.

Hint 12

Front 13

COMPLETE METAMORPHOSIS

Back 13

A type of metamorphosis characterized by 4 dramatically different stages.

Hint 13

Front 14

CONSUMER

Back 14

a living thing that needs to eat to obtain energy

Hint 14

can not make its ownfood

Front 15

PRODUCER

Back 15

a living thing that can make food with energy from the sun

Hint 15

they start the food chain

Front 16

HERBIVORE

Back 16

An animal that only eats plants

Hint 16

another example: a deer feeds on grass

Front 17

OMNIVORE

Back 17

a living organism that eats plants and animals

Hint 17

Example: Human

Front 18

In what ways are the two types of metamorphosis different? How are they Similar?

Back 18

Different:

-Complete Metamorphosis: A type of metamorphosis characterized by 4 dramatically different stages. ( egg--> larva-->pupa--> adult)

-Incomplete Metamorphosis: metamorphosis where an animal looks the same as an adult as they did as a baby. They simply grow larger.

(egg-->nymph-->adult)

They are similar in that they both start their first stage with an egg.

Front 19

How do people affect an ecosystem? Explain a negative and a positive way.

Back 19

Negatively: People affect an ecosystem negatively when they catch fish from the seas.

Positively: People affect an ecosystem when they preserve natural resources.

Front 20

ECOSYSTEM

Back 20

An ecosystem includes all of the living things (plants, animals and organisms) in a given area, interacting with each other, and also with their non-living environments

Hint 20

Front 21

How is a herbivore different from a carnivore?

Back 21

Herbivore eats only plants, while the carnivore eats only meat.

Front 22

How does a secondary consumer (in a food chain) get its energy when it eats a primary consumer?

Back 22

it gets its energy as it eats the primary consumer which is the rabbit and the rabbit gets its energy from the producer which makes its own food by the energy of sunlight.

Hint 22

Example:

Secondary consumer--> fox

Primary Consumer--> rabbit

Producer--> plants
