37- The sun, root of all energy in an ecosystem

38- it absorbs light to be processed

39- Oxygen

40- The plant would be unable to preform

Explanation:

37 - The sun

38 - it absorbs the sunlight and turns it into energy

39 - Oxygen

40 - Without much light it will take much longer for the plant to photosynthesize

41 - the plant brings water through its roots, the plant then takes carbon dioxide from the air, the leaves absorb sunlight then the plant uses the sunlight to turn water and carbon dioxide into oxygen and glucose
