Question

Contributions to the ecosystem by the environment are in the form of: _________

a. N2, CO2 and H2O
b. CO2, H2O and O2
c. Ar, H2O and O2
d. H2O and O2

Answer 1

The contributions to the ecosystem by the environment are in the form of CO2, H2O, and O2.

Step-by-step explanation:

The contributions to the ecosystem by the environment are in the form of CO2, H2O, and O2. Carbon dioxide (CO2) is used by autotrophs (plants, algae, and some bacteria) during photosynthesis to produce glucose and release oxygen (O2) as a byproduct. Water (H2O) is essential for all living organisms and plays a critical role in many biological processes.
