Which of the following has bacteriochlorophylls and uses alcohols for carbon?
a. chemoautotroph
b. photoheterotroph
c. chemoheterotroph
d. photoautotroph

Photoheterotrophs

Explanation:

The photoheterotrophs are the organism that depends on the organic matter which is already produced by the other organism for its nourishment.

They obtain their energy from sunlight and the source of carbon for them is  some organic material but they cannot use carbon dioxide as a soul source of energy.

These organism use sunlight hence the term photo is used for them and obtain carbon from organic matter hence called as heterotrophs.

Hence, the correct answer is option B.

the two answers are a, the population of birds with large beaks will increase on the island, and c, the trait for large beaks will be passed on to future generations through natural selection. the reason for that is because if the birds that have beaks developed for eating small seeds lose all of their food, they will go hungry and eventually starve because they physically cannot eat the large seeds, therefore making the population of large beaked birds higher. also, if the trait of large beaks are dominant on the island over small beaks, then over time the large beaked birds will reproduce more and more, while the smaller beaked birds will reproduce less and less because they can't survive with the food provided. that leads to the trait of small beaks disappearing and the trait of large beaks taking over the island.

to this answer it would be edge enhancement
