Answer:
d. 6 molecules, 18 carbons total
Explanation:
In a Calvin cycle 3CO₂ is combines with 3 RUBP to form 6 molecules of glyceraldehyde-3-phosphate (G3P). One molecule of G3P has three fixed carbon atoms, Thus to make one molecule of six carbon glucose molecules will take two molecules of G3P. Therefore six turns of the Calvin cycle required to make one glucose.
So, as per question, 6 molecules of G3P will required 18 carbons.
Since the hemlock and spruce trees are old, they are K-strategists. K-selected species, or K-strategists, are species that produce only a few offspring that live for a long time. r-selected species, or r-strategists, on the other hand are able to produce more offspring which survive for a shorter period of time.

Answer;
Without the keystone species, the rocky inter-tidal ecosystem would be dramatically different or cease to exist altogether
Explanation;
Keystone species have low functional redundancy. This means that if the species were to disappear from the ecosystem, no other species would be able to fill its ecological niche.
For instance; the starfish Pisaster ochraceus is a keystone species in the rocky marine inter-tidal communities off the northwest coast of North America. It feeds on the mussel Mytilus californianus and is responsible for maintaining much of the local diversity of species within certain communities.
