Decomposers (fungi, bacteria, etc) like the name suggests decompose rests of food and organisms and send the nutrients back into the earth.
Questions 2&3:
An autotroph is an organism that produces its own food (like plants do through photosynthesis) and a heterotroph is an organism that cannot produce its own food and has to seek out other sources of food.
Question 4:
Grass, Dragonfly, Trout, human
Question 5:
Bean plant, rabbit, fox, bacteria
