Classification of Living Things

​Review of the past lesson...

Multiple Choice

What is the basis for the earliest classification system of organisms?

• physical characteristics

• differences in habitat

• evolutionary relationships

• reproductive patterns

Multiple Choice

Organisms are classified by their characteristics.

Two of the kingdoms in Eukarya are Plantae and Animalia.

The examples of organisms in the kingdom Animalia are missing.

Find examples of organisms in the kingdom Animalia.

• birds, fish, mammals

• mushrooms, yeast, mold

• fruits, trees, grasses

Multiple Choice

What is the difference between a kingdom and a phylum in the classification of living things?

• A kingdom is broader than a phylum

• A phylum is broader than a kingdom

• Both are the same

• Neither is a classification

Multiple Choice

Which kingdom contains members who are prokaryotic?

• Archaebacteria and Eubacteria
• Archaebacteria and Protista
• Eubacteria and Animalia
• Eubacteria  and Fungi

Multiple Choice

What kind of vertebrate is this?

Multiple Choice

Humans, lizards, and frogs all have a backbone as do all the organisms in the pictures shown. They all belong to this phylum.

• cnidarians

• echinoderms

• annelid worms

• chordata

Multiple Choice

What is the primary function of the vertebral column in vertebrates?

• Support for the body

• Protection of organs

• Production of blood cells

• Storage of minerals

Multiple Select

What are the three classifications of mammals mentioned in the text?

• Eutherian or placental mammals

• Marsupials

• Monotremes

• Reptiles

Multiple Choice

What are the characteristics of monotremes?

• They lay eggs instead of giving live birth

• They have fur and give live birth

• They are warm-blooded

• They have feathers

Multiple Choice

What are marsupials?

• Mammals that lay eggs

• Mammals that give birth to underdeveloped young

• Mammals that live in water

• Mammals that can fly

Multiple Choice

What are the characteristics of Eutherian or Placental Mammals?

• Live birth

• Lay eggs

• Cold-blooded

• Short gestation period

Multiple Choice

What are the two types of fishes mentioned in the text?

• Bony fishes and cartilaginous fishes

• Freshwater and saltwater fishes

• Predatory and non-predatory fishes

• Tropical and temperate fishes

Assessment

Multiple Choice

An animal cannot control its body temperature internally and must bask in the sun. What is it called?

• Homeothermic

• Endothermic

• Poikilothermic

• Ectothermic

Multiple Choice

• Marsupial
• Bird
• Mammal
• Reptile

Multiple Choice

Which organism would MOST LIKELY be classified as an amphibian?

• Salamander
• Frog
• Lizard
• Turtle

Multiple Choice

Why do endothermic animals need to eat often?

• Endothermic animals eat less frequently to conserve energy.
• Endothermic animals rely on external heat sources for energy.
• Endothermic animals need to eat often to maintain their energy levels and body temperature.
• Endothermic animals can survive long periods without food.

Multiple Choice

A turtle has dry, scaly skin and lays eggs on land. What class does it belong to?

• Amphibia

• Mammalia

• Reptilia

• Aves

Multiple Choice

Which organism plays an important role in controlling insect populations?

• Plants that attract pollinators
• Predators like birds and ladybugs
• Parasites like mosquitoes and ticks
• Fungi that decompose organic matter

Multiple Choice

Which animal helps maintain ecosystem balance as an apex predator?

• cow

• snake

• sheep

• hawk

Multiple Choice

A scientist is studying animals without a backbone like earthworms and insects. What are these animals called?

• Invertebrates
• Amphibians
• Mollusks
• Vertebrates

Multiple Choice

A bear gives birth to live young and feeds them milk. Which class does it belong to?

• Mammal
• Bird
• Amphibian
• Reptile

Multiple Choice

Which animal shows both aquatic and land adaptations?

• Salamander
• Turtle
• Penguin
• Frog

Multiple Choice

Why are mammals and birds grouped together as endothermic animals?

• Mammals and birds are endothermic as they have feathers and fur.
• Mammals and birds are endothermic because they live in warm climates.
• Mammals and birds are endothermic due to their large size.
• Mammals and birds are endothermic because they can internally regulate their body temperature.
