IB ESS Topic 2.1 Species and Populations

Applications and skills

Interpret graphical representations or models of factors that affect an organism's niche
Explain population growth curves in terms of numbers and rates

Multiple Choice

If an area has all the wolves that it can support, the wolf population has reached its _____________.

carrying capacity

population density

immigration

death rate

Multiple Choice

Which of the following is the amount of organisms in a given amount of space?

Carrying capacity

Limiting factor

Emigration

Population density

Multiple Choice

When a population grows past the ecosystem's carrying capacity, what happens to the population?

Continues to grow

The population starts to die off to return to carrying capcity

The population will go extinct due to lack of resources

The population grows then finds a new carrying capacity

Multiple Choice

What limits Population Growth?

birth rates increasing

resources being used up

natural selection taking place

none of the above

Multiple Choice

Exponential population growth can be described as

growth when resources are limited

a j-shaped curve

a s-shaped curve

growth that reaches carrying capacity

Multiple Choice

Look at this image- What is the carrying capacity of this population?

5000

2000

1000

Multiple Choice

Look at this image- What is the carrying capacity of this population?

5000

2000

1000

Multiple Choice

Carrying capacity of a habitat is determined by

population growth rate

limiting factors

j versus s type population growth

r and k survival strategies

Multiple Choice

A species' realized niche is different from its fundamental niche because of

abiotic factors of the environment like sunlight

interspecies interaction like competition and predation

population fluctuating around an equilibrium level

carrying capacity of the environment changing over time

Multiple Choice

A fundamental niche is

all conditions in which a species could survive

the actual conditions in which a species survives

trophic level, i.e. primary producer, secondary consumer, etc.

the number of individuals an environment can support sustainably

Multiple Choice

Which organism do the owl and the weasel compete for in the food web?

Hawk

Spider

Grasshopper

Shrew

Multiple Choice

Why are decomposers necessary?

Because we compose too much...

To take basic materials and make them more complex...

To take complex materials and break them down to basic stuff...

So demusic can be really good...

Multiple Choice

At which trophic level can you find an herbivore?

1st Level

2nd Level

3rd Level

4th Level

Multiple Choice

In a forest ecosystem, a food chain might look like this:
green plants → rabbit → fox → panther

If the green plants are destroyed in a forest fire, which short-term effect will this have on the organisms in this food chain?

There would be fewer rabbits for the foxes to eat.

The panthers would have to begin to eat green plants.

There would be an increase in the fox population

There would be more green plants for the rabbits to eat

Multiple Choice

According to the food web shown, what would occur if there were a drastic decrease in the squirrel population?

There would be fewer vultures

There would be more nuts and seeds.

There would be fewer vultures & there would be more nuts and seeds.

There would be more grass.

Multiple Choice

Why are food chains, such as the one shown, limited to 4-5 organisms?

There are not more organisms in the ecosystem

Organisms must share resources

Energy transfers are inefficient

They are only limited when organisms are living on land.

Multiple Choice

Autotrophs are organisms that

rely on other organisms for their energy & food supply.

consume plant & animal remains and other dead matter.

use energy they take in from the environment to convert inorganic molecules to organic molecules.

obtain energy by eating only plants.

Multiple Choice

All life on Earth exists in a region known as

an ecosystem

a biome

the biosphere

ecology

Multiple Choice

An important abiotic factor in ALL ecosystems is the

ecology

climate

plants

animals

Multiple Choice

The living factors of an ecosystem, such as plants, animals, & fungi are called

biotic factors

abiotic factors

ecosystem

population

Multiple Choice

The non-living parts of an ecosystem, such as water, sun, & oxygen are called

habitat

abiotic factors

biotic factors

ecology
