Flashcards in Chapter 1: Energy Matter Deck (19):
1

-share set of characteristics that collectively set apart from nonliving matter
-have biological molecules that contain instructions for building other molecules
-gather energy and materials form their surroundings to build new biological molecules

living organisms

2

characteristics that depend on the level of organization, but do not exist at lower levels

emergent properties

3

many single cells, such as bacteria and protozoans

unicellular organisms

4

plants and animals are made up of groups of interdependent cells

multicellular organisms

5

groups of organisms of the same kind that live together in the same place

populations

6

group of all the populations of different organisms that live in the same place

community

7

includes the community and the nonliving environmental factors with which it interacts

ecosystems

8

includes all the ecosystems of Earth's waters, crust, and atmosphere

biosphere

9

the ability of a cell or organism to extract energy from its surroundings and use that energy to maintain itself , grow and reproduce

metabolism

10

electromagnetic energy in sunlight is absorbed and converted into chemical energy in biological molecules

photosynthesis

11

organisms break down biological molecules (with oxygen) releasing chemical energy for cellular activities

cellular respiration

12

-photosynthetic organisms
-assemble complex molecules (sugars) from water and CO2

primary producers

13

-animals
-feed directly or indirectly on the complex of molecules manufactures by plants

consumers

14

-bacteria and fungi
-feed on dead organisms and break down biological molecules into raw materials, which may then be recycled by producers

decomposers

15

-regulation of internal body temperature within a narrow range
-steady internal condition

homeostasis

16

process in which parents pass on their DNA and produce offspring that resemble them

reproduction

17

transmission of DNA from one generation to another

inheritance

18

series of changes in which a fertilized egg is transformed into an adult

development

19

sequential stages through which individuals develop

life cycle
