The growing problem In the video is when water is not getting in the tree roots.
<span>When a plant undergoes photosynthesis, one of the by-products is oxygen or CO2.

<span>The correct answer is c. producer: elodea, consumer: squirrel, decomposer: crayfish, abiotic: phosphates.</span>
Elodea-the aquatic autotrophic plant (makes its own food) which does photosynthesis,
Squirrel-animal, heterotrophic organism (consume food which plant produce), <span>Crayfish- feed on animals and plants, either living or decomposing, and detritus,</span> <span>Phosphates-non-living, organic or inorganic molecule.</span>
