photosynthesis materials aka H20 CO2 ( water and carbon dioxide)
Answer:The placement of fossils throughout the sruface layers of earth
Explanation:
If organisms that lived there before had exceeded the carrying capacity then the ecosystem would no longer be able to sustain life
Hello! Autotrophs make their own food (plants) and heterotrophs consume other organisms for energy (consumers.) Autotrophs use the process of photosynthesis to produce the oxygen as one of its products. Heterotrophs use the oxygen produced by the autotrophs to perform cellular respiration, which releases carbon dioxide that plants use; it's a balanced cycle. Hope this helps!
