Answer

Answer:

Question 1: B. 7 Question 2: D. Autotrophs

Explanation:

Step1: Recall pH - scale knowledge

The pH scale ranges from 0 - 14. A pH of 7 is neutral. Values below 7 are acidic and above 7 are basic.

Step2: Recall photosynthesis - organism knowledge

Autotrophs, such as plants and some algae, use photosynthesis to convert light energy into chemical energy (food). Heterotrophs obtain food by consuming other organisms. Sharks and frogs are heterotrophs.
