Answer:

Acids have a pH value of less than 7, the closer it is to one, the more acidic they are

e.g. HCL (hydrochloric acid) found in the stomach which has a pH of between 1.5 and 3.5

Alkaline solutions have pH values of over 7 (neither acids nor alkalis have a pH of 7 as it's neutral) and the closer it is to 14, the more alkaline they are

e.g. sodium hydroxide which has a pH of 14

Describe how the ecosystem changed from figure 1 to figure 4.<br> no links, please. <br> thank you
AysviL [449]

Answer:

In the ecosystem, the tides of the water rise in each figure. In figure 4, there is an increase in land animals present, and a lower amount of aquatic animals present. In the first figure, there are no birds, however there are multiple in the rest of the figures, this is possibly due to migration in the winter or that the ecosystem has drawn birds near. The types of plants change throughout each figure which is most likely to new adaptations such as more water available. The tides most likely rose because of more precipitation.

I hope this helped.
