I’m a group of species that have similar characteristics.

I’m the arrangement of kingdoms into larger groups.

I’m the kingdom that includes organisms—either unicellular or with a simple multicellular structure—that don’t fit easily into animals, plants, or fungi.

I’m the system for naming species developed by Linnaeus.

I’m the kingdom that contains unicellular organisms with no nucleus.

I’m the kingdom that includes plants such as trees, grass, and moss.

I’m the science of naming and classifying organisms.

I ask a series of questions that can be answered in only two ways.

I’m the kingdom that includes mushrooms, molds, and yeasts.

I’m the process of arranging organisms into groups based on similarities.

I’m the kingdom that includes animals, from lions and tigers to bugs.

A process in which members of a species that are best suited to their environment survive and reproduce at a higher rate than other members of the species

What is the preserved traces or remains of living things?

The evolution of new species from an existing species

Any inherited trait that gives an organism an advantage in its particular environment

Organisms made up of a single cell

An example is a slight change in the shape of a fin that may increase a fish’s chance of survival by helping it swim faster.

In some cases of this, one species develops into completely new species.

This has cells that are organized into tissues, organs, and systems.

Having one of these in common is part of the theory of natural selection.

By examining these, scientists can identify periods of mass extinctions.

During Earth’s history, there have been several of these periods.

Living things in the ocean 3.8 billion years ago were this type. What is the correct vocabulary term?

Charles Darwin proposed the idea of this process.

An example of this is the small leg bones found in the bodies of whales. What is the correct vocabulary term?

This may occur when the environment changes dramatically.

An early relative

Living things made up of many cells

True or False:

Opportunists are species that have adaptations to reproduce rapidly if their population falls below carrying capacity.

True or False:

Carrying capacity is the maximum number of individuals the Earth can support.

The movement of individuals into a population is called emigration.

A limiting factor affects a population’s growth.

Pollution is the addition of harmful substances to the environment.

Population density is a measure of the number of individuals in a percentage of a given area.

Population dynamics is the study of why populations change and when they change.

The movement of individuals out of a population is called immigration.

Species that have adaptations that allow their populations to grow at rapid rates for long periods of time are competitors.

These include algae, dandelions, bacteria, and insects.

If a population’s size increases but all of the individuals remain in the same area, this increases too.

Emigration is _________________

Two examples of this are elephants and saguaro cacti.

Pollution is ______________

This can increase a population or help stabilize a declining population.

Carrying capacity is ______________

This involves the study of why the number of individuals in a population changes.
