Q

cladogram

A

diagram that shows relatedness of organisms

17
Q

all energy comes from what?

A

the sun

18
Q

autotrophs get energy from what

A

nonliving sources

19
Q

consumers are also called what

A

heterotrophs

20
Q

produces are also called what

A

autotrophs

21
Q

where do heterotrophs get their energy from

A

living things

22
Q

where does photosynthesis get its energy

A

the sun

23
Q

during chemosynthesis where does it get its energy from

A

chemicals

24
Q

how do consumers get their energy?

A
  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
25
Q

food chains:

A

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

26
Q

food webs

A

show multiple food chains at once, and how they interconnect

27
Q

trophic pyramids

A

models that show how energy flows through an ecosystem

28
Q

energy pyramid

A

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

29
Q

numbers pyramid

A

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