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

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)?
