nonliving sources

Question 19

consumers are also called what

heterotrophs

Question 20

produces are also called what

Answer 20

autotrophs

Question 21

living things

Question 22

where does photosynthesis get its energy

Answer 22

the sun

Question 23

during chemosynthesis where does it get its energy from

Answer 23

chemicals

Question 24

how do consumers get their energy?

Answer 24

1. they eat other organisms to get energy
2. then they breakdown macromolecules inside of them to release ATP in a process called cellular respiration

Question 25

food chains:

Answer 25

trace a single flow of energy and show trophic levels= the levels of nourishment in a food chain

Question 26

food webs

Answer 26

show multiple food chains at once, and how they interconnect

Question 27

trophic pyramids

Answer 27

models that show how energy flows through an ecosystem

Question 28

energy pyramid

Answer 28

represents the energy available at each trophic level; levels ALWAYS get smaller as you go up the pyramid

Question 29

numbers pyramid

Answer 29

represents the number of organisms at each trophic level; since energy decreases as you go up the pyramid, fewer organisms can be supported
