provide to larger organisms?
food

What is the role of a decomposer
when plants die?
to eat the bacteria in the soil
to store carbon for the plants
to break down plant proteins
to turn nitrates into nitrogen gas
Which of the following best
describes the role of roots
and stems in a plant?
Roots and stems transport water
and minerals to the leaves so that
photosynthesis can occur.
Roots and stems help the plant
move and keep cool in hot weather.
