There are many different species.

There are few herbivores.

There is a large population of only one species.

5

5

Which of the following is a biotic part of the forest?

The graph below shows the number of organisms in an ecosystem over time. Which biological concept is BEST illustrated by the graph?

natural selection.

carrying capacity.

geographic isolation.

predator-prey relationships

5

Consider the graph below. Which statement below BEST explains what is occurring during section II in the population graph?

The population is at its carrying capacity.

The population is affected by density-dependent factors.

The population is smaller than the carrying capacity.

The birth rate is exceeding the death rate.

5

Ecosystems are made up of both living organisms and non-living things. The picture below shows some of the living organisms and the nonliving things in a desert ecosystem. A.) Identify one living organism in the ecosystem. B.) Identify one non-living thing in this ecosystem with which the living organism you named in PART A interacts. C.) Explain why it is important for the living organism to interact with the nonliving thing you identified in Part B.

5

Suppose an oil tanker ran aground and broke apart near the mouth of the Mississippi River and millions of gallons of crude oil and spilled out of the ship. DESCRIBE TWO effects this would likely have on the ecosystem in the surrounding environments.

5

________ is the source of energy for almost all living things.

Water

Sunlight

Food

Oxygen

5

Abiotic are all of the _____________ components in an ecosystem.

Living

Community

Non-living

Organism

5

Moose are grazing animals. They eat grass. If there were too many moose in an area, there would probably be

fewer predators of bison

many other large grazing animals

less grass and more bare soil

tall shrubs

5

What is the definition of carrying capacity?

The maximum population size of a species that the environment can sustain.

The living parts of an ecosystem.

A group of interdependent organisms together with the environment they inhabit

All the plants and animals that live in the same area and interact with one another.

5

The plant a ladybug lives on, the aphids that the ladybug eats, and the birds that eat the ladybugs are all

physical factors of the environment

biotic parts of the environment

abiotic parts of the environment

involved in predator-prey relationships

5

When a population grows larger than its carrying capacity, limiting factors in the environment cause the population to

increase

decrease

stay the same

co-evolve

5

A population that has reached the largest number of individuals that the environment can support over a long period of time

has no limiting factors

has changed from a food chain to a food web

has reached its carrying capacity

contains only top consumers

5

Limiting factors such as landslides, forest fires, floods and extreme weather are all

ways organisms compete for resources

natural disasters

predator-prey cycles

caused by ecological succession

5

What is an ecosystem?

A system to stop pollution

All of the biotic and abiotic factors in an area that interact with each other.

environmental factors that limit the success of a population

Largest number of individuals an ecosystem can support

5

Which type of succession begins with rock, which causes growth to take longer?

Primary

Secondary

Tertiary

Quatranary

5

Which scenario would be considered an example of Secondary Succession?

A volcano erupts causing lava to harden and leaving nothing but rock.

A forest fire breaks out burning down everything in its path but leaving soil for growth to begin again.

All of these are correct

Glaciers retreat leaving rock in order for growth to start again.

5
