Classification
What is the definition of classify?
-to organize into similar groups
What is the definition of a metamorphosis?
A metamorphosis is the complete change from one thing into another
What is the definition of reproduction?
To make more of the same kind
What is a habitat?
A habitat is where an animal lives within an ecosystem.
A producer is an organism that creates its own energy from the sun.
Example:
Plants!
True or False:
Invertebrates have a backbone.
False!
Invertebrates do NOT have a backbone!
What is the definition of a life cycle?
What is the definition of offspring?
The babies of an animal.
(Animals pass down traits, behaviors, and characteristics to their offspring.)
Biotic factors are living things within an ecosystem.
Examples:
-insects
-frogs
-deer
-plants
What is the definition of a primary consumer? Give one example.
A primary consumer is an animal that eats producers.
Examples
-Any herbivores (animals that only eat plants)
List the 3 cold-blooded animal classes.
2. Reptiles
3. Amphibians
(Birds and mammals are warm-blooded!)
What is the definition of a life span?
A life span is how long it takes for an individual animal to complete its life cycle.
What is the definition of heredity?
The passing of traits from parents to their offspring.
Abiotic factors are the nonliving things in an ecosystem.
Example:
-sunlight
-air
-water
-rocks
What is the definition of a secondary consumer? Give one example.
A secondary consumer is an animal that eats other animals.
Examples:
-any carnivores (animals that only eat meat)
-any omnivores (animals that eat both meat and plants)
Do vertebrates have an EXOSKELETON or an ENDOSKELETON?
Endoskeleton: skeleton inside the body
Exoskeleton: skeleton outside the body
1. egg
2. larva
3. pupa
4. adult
Are the following examples of LEARNED BEHAVIORS or INHERITED BEHAVIORS?
1. a dog know to sit when his owner commands him to "sit"
2. A bear knows she can get food out of a garbage can
3. A whale at Sea World knows to jump when its trainer gives a signal
Learned behaviors
(Learned behaviors are behaviors animals learn by interacting with their environment.)
What is the definition of an animal population? Give an example of an animal population that could live in a pond.
An animal population is all the members of a species that live in an ecosystem.
Examples:
-frogs
-turtles
-flies
-deer
What is the definition of competition within a food web?
Competition is when animals compete for the same food.
What is the biggest invertebrate class?
1. arthropods
2. mollusks
3. cnidarians
4. sponges
5. worms
6. echinoderms
Arthropods
(Arthropods include insects!)
Describe how a frog goes through a metamorphosis.
A frog begins its life as a tadpole, living in the water.
Next, it begins to grow legs and its tale shrinks.
When complete, a frog loses its tale completely and has strong legs. An adult frog lives mostly out of the water.
Are the following examples of LEARNED BEHAVIORS or INHERITED BEHAVIORS?
1. A opossum knows to play dead when threatened by a preadator.
2. A squirrel begins to store up nuts as the weather gets colder.
3. Baby sea turtles know to move toward the ocean once they hatch.
Inherited behaviors
(Inherited behaviors, or insitics, are behaviors animals are born knowing how to do.)
Which biome would you most likely find a pond ecosystem?
1. desert
2. tundra
3. deciduous forest
4. taiga
Deciduous Forest
(The desert is a dry biome. The tundra is a frozen biome. The taiga is cold all year long. Deciduous means the leaves fall of tress, but a forest is the perfect place for a pond!)
How would the disappearance of a primary consumer impact a food web?
-The secondary consumers would struggle to find food.
-The food chain would be broken.
