Why do plants produce more carbon dioxide than oxygen during the night?
o
a. respiration can happen without sunlight, but photosynthesis
cannot.
b. respiration can only occur when there is no available sunlight.
o
o
c. photosynthesis only produces carbon dioxide during the night.
o
d. respiration produces oxygen during the day and carbon dioxide at
night.

During daylight hours, plants take in carbon dioxide and release oxygen through photosynthesis, and at night only about half that carbon is then released through respiration. However, plants still remain a net carbon sink, meaning they absorb more than they emit.

The answer is A. Respiration can happen without sunlight, but photosynthesis cannot.

Hope it helps!

i think that you are smart and you should fit for it out

1: most common garden plants prefer loam — soils with a balance of different-sized mineral particles (approximately 40% sand, 40% silt, and 20% clay) with ample organic matter and pore space. however, some plants grow better in sandy soils, while others are well-adapted to clay soils.

2: available water capacity is the maximum amount of plant available water a soil can provide. it is an indicator of a soil's ability to retain water and make it sufficiently available for plant use. available water capacity is the water held in soil between its field capacity and permanent wilting point.

3: it is the same for all living things (plants and animals). it also includes very tiny organisms that our eyes cannot see. they are known as microorganisms, and include viruses, bacteria and fungi.
