The ph of the water in several lakes in norway and sweden had decreased to below 5.0 due to an increase in acid rain. what is most likely to happen in these lakes?

What will most likely happen in these lakes is that there will be a decline of several fish populations. The correct answer is A.

Explanation:

The options attached to the question are given below:

A. The decline of several fish populations

B. An increase in the number of fish.

C. An increase in the number of primary producers.

D. Increased predator- prey relationship.

The fishes, just like any other living organisms has ideal body temperature and pH at which they act best. The ideal pH for fish living in lake water is between 6 and 8. If the pH is reduced below this value then the water will become acidic and this will be toxic for the fish population living in the lakes. Therefore, those fish that can not cope will die and there will be a decrease in the fish populations.

spiders belong to a group of arachnids.

arachnids have the following traits :

they have two body parts.

they have eight legs unlike insects which have 6 legs.

they have no wings.

these traits distinguish them from insects.

the information that antonio is doubting us the statement that spiders differences are as a result of being first to evolve.

this is because the evolution of one species is independent of the other species.

i believe it would cause an increase of percipitation, though i could be wrong. so i would say b is the answer.
