Energy is permanently lost in the form of _______ during energy transfers among organisms.

heat

In ecosystems, organisms that eat other organisms are called consumers, or

heterotrophs

Select all the statements that are true about ground asexual reproduction.

In the image, antibiotic-resistant bacteria have increased reproductive success due to ----, which is a mechanism of -----.

natural selection; evolution

A leaf is composed of several tissues organized to work together and is a(n)------ of a plant.

organ

A living thing or individual is also called a(n)

organism

Match each category of organisms with their method of obtaining energy.

-primary producer: autotroph that obtains energy and nutrients from nonliving sources. - consumer: heterotroph that obtains energy and nutrients by eating other organisms -decomposer: heterotroph that obtains energy and nutrients from wastes and dead organisms

Select ways that the human body can maintain a body temperature of about 37*C while outside on a cold day.

-shivering - diverting blood from the body surface

Select all of the characteristics of natural selection.

-it favors adaptations to the current environment - genetic variability in organisms is required.

Match each example to its correct level of biological organization.

-organism: bacterial cell -community: the plants,animals,and microorganisms that inhabit a particular field - molecule: DNA -ecosystem: organisms, water, air, and nutrients in a desert area - organ system: heart and blood vessels -atom: carbon

-organization -energy use -maintenance of internal constancy -reproduction, growth, and development -evolution

Select all of the following that make up a community.

-populations of animal species -populations of plant species - populations of prokaryotes and protists

What is the basic unit of life and consists of a membrane enclosing water, DNA, and other chemicals?

Cell

What is the term for all the populations of different species that occupy the same location at the same time?

Community

What biological level includes the living and nonliving components of a particular area?

Ecosystem

New complex functions and characteristics that arise when the smaller components of an organism interact are called ____ properties.

Emergent properties

What statement describes a cell?

The smallest unit that can be called life

T OR F: The ultimate energy source in most ecosystems is the sun.

True

A level of biological organization called the ---- includes all parts of Earth and its atmosphere where life can survive.

biosphere

A living thing, or organism, exhibits certain properties of life and is composed of one or more ------, the basic units of life.

cells

Life consists of

cells that are organized, use energy, and are able to reproduce.

ecosystem

Different components of biological organization can interact to produce more complex functions called --- properties

emergent properties

All living things are composed of one or more cells, use ----- to grow and reproduce, and maintain a state of internal constancy.

energy

The change in genes of a population over multiple generations can also be referred to as

evolution

Shivering or restricting blood flow to maintain body temperature is an example of what characteristic of life?

homeostasis

Using a process called -----, living organisms maintain a state of internal constancy or equilibrium, such as a constant range of temperatures, nutrients, or water.

homeostasis

What describes the state of internal constancy maintained by an organisms?

homeostasis

What is a group of joined atoms, such as deoxyribonucleic acid (DNA)?

molecule

Atoms can bond together to form

molecules

Compartments within cells that carry out specific functions are called

organelles

What are membrane-bounded compartments within eukaryotic cells that carry out specialized functions?

organelles
