Evolution

Question 11

organism that captures energy from the sun

Answer 11

producers/autotrophs

Question 12

can not make its own energy so it consumes other organisms

Answer 12

consumers/heterotrophs

Question 13

Animal that freeds on plants

Answer 13

primary consumer

Question 14

eat primary consumers. They are carnivores (meat-eaters) and omnivores (animals that eat both animals and plants).

Answer 14

Secondary consumers

Question 15

Answer 18

Omnivores

Question 19

are organisms that break down dead or decaying organisms

Answer 19

Decomposers

Question 20

The directional flow of materials and energy from one organism to another is graphically represented by arrows.

Answer 20

Food Chain

Question 21

a series of organisms related by predator-prey and consumer-resource interactions

Answer 21

Food web

Question 22

s a graphical model of energy flow in a community. The different levels represent different groups of organisms that might compose a food chain.

Answer 22

Energy pyramid

Question 23

the series of processes by which carbon compounds are interconverted in the environment, chiefly involving the incorporation of carbon dioxide into living tissue by photosynthesis and its return to the atmosphere through respiration, the decay of dead organisms, and the burning of fossil fuels.

Answer 23

Carbon Cycle

Question 24

is the biogeochemical cycle that describes the movement of phosphorus through the lithosphere, hydrosphere, and biosphere.

Answer 25

phousphorus cycle

Question 26

s the observed process of change in the species structure of an ecological community over time.

Answer 26

ecological succesion

Question 27

which are the first to colonize previously disrupted or damaged ecosystems, beginning a chain of ecological succession that ultimately leads to a more biodiverse steady-state ecosystem.

Answer 27

wfinal stage of succession, in which the species composition remains relatively stable until a disturbance

Answer 28

climax community

Question 29

that eats plants

Answer 29

herbivores
