Because of human-driven increased levels of carbon dioxide in the atmosphere, there is more CO2 dissolving into the ocean. The ocean's average pH is now around 8.1 , which is basic (or alkaline), but as the ocean continues to absorb more CO2, the pH decreases and the ocean becomes more acidic.

There are different trophic levels at each stage. Trophic levels determine the amount of energy at each stage of the food chain. For example, the energy is 100% at the producer (plant), so it's the 1st trophic level, and so on. Energy amounts decrease as you go up a food chain, and you rarely find more than 5 animals in one because there is not enough energy left for the 6th consumer
