Intro to Invertebrate 11/128

Introduction to the
Animal Kingdom

Which of these is an “animal”?

Multiple Choice

Which of the Organisms on the last slide are animals?

• Spider

• Dog

• Worms

• All of them

Multiple Choice

What percentage of Animals are Invertebrates?

• 95%

• 5%

• 25%

• 75%

Biology = study of life

Physiology = Study of
the functions of organs
Anatomy = the
structure of the
organism/organs
Zoology = study of
animals

Animal Functions

1.Feeding:

Herbivore = eats plants

Carnivore = eats animals

Omnivore = eats plants and animals

Detritivore = eats decaying organic material

Filter Feeders = aquatic animals that
strain food from water

Examples: whale
shark, sponges

Parasite = lives in or on another organism
(symbiotic relationship)

Examples:
roundworms,
tapeworms, ticks, lice

2. Respiration:

Take in O2 and
give off CO2

Lungs or gills

or through skin
(diffusion)

3. Circulation:

Very small animals rely on diffusion
Larger animals have circulatory system

4. Excretion:

Primary waste product is ammonia

The kidney is the main organ of excretion

5. Response:
Nervous System

Stimulus → Response

6. Movement:

How they move can vary
(swim, crawl, fly, run, slither)
*Some animals don’t move at all!

What is the difference between:

Quadrupedal & Bipedal

Terrestrial & Aquatic

Sessile & Motile

7. Reproduction: Most
reproduce sexually =
genetic diversity

Many invertebrates can
also reproduce asexually

Multiple Choice

an animal with a backbone

• vertebate

• invertebrate

Multiple Choice

an animal without a backbone

• vertebrate

• invertebrate

Open Ended

What is the difference between bipedal and quadrupedal?

Multiple Select

Which of the following organism above are considered "Heterotrophic"?

• Deer

• Fern Plant

• Apple Tree

• Owl

• Skunk

Multiple Choice

Does a Eukaryotic Cell have DNA?

• Yes

• No

Multiple Choice

All animals are

• multicellular and heterotrophic

• multicellular and autotrophic

• unicellular and heterotrophic

• unicellular and autotrophic

Multiple Choice

Animals are heterotrophic. This means

• They must produce their own energy and nutrients.

• They must consume other organisms to obtain energy and nutrients.

• They must ingest their food and then digest it.

• They are able to store excess food as fat or glycogen.

Multiple Choice

Some animals have the ability to reproduce asexually. This means

• Only one parent is needed for reproduction.

• The offspring will look identical to the parent.

• This will limit the genetic variation of the species.

• All of the answer choices are true about asexual reproduction.

Multiple Choice

Animals that can move from place to place are considered

• sessile

• motile

• low energy

• mobile

Multiple Choice

Animal that are permanently attached to a surface are called

• motile

• mobile

• sessile

• sedentary

Multiple Choice

An example of an advantage for sessile animals would be

• They can't move about to find food, shelter, and mates.

• They have a low energy requirement.

• They can't avoid predators.

• There are no advantages to being a sessile animal.

Multiple Choice

Animals are heterotrophic. This means

• They must produce their own energy and nutrients.

• They must consume other organisms to obtain energy and nutrients.

• They must ingest their food and then digest it.

• They are able to store excess food as fat or glycogen.

Multiple Choice

Animals can respire with lungs, gills, or ______

• Become Autotrophs

• Through lungs anyway

• through gills anyway

• Diffuse through skin

Multiple Choice

Which comes first, the response or the stimulus?

• The response

• The stimulus

• They both come first

• They both come last
