Abiotic Factors

Temperature: If the temperature in the Maritime Forest were to go up or down, it would obviously affect the animals by making them too hot or too cold.  Think about it- if you were wearing short sleeves and shorts, and that was the only clothing you had, then the temperature suddenly dropped, surely you'd be cold.  The same goes for animals.  They naturally have fur that keeps them comfortable in the temperatures that they are used to being in.  When the temperature suddenly changes, they could get hypothermia or overheat.  Aside from that, the ground could freeze and the plants couldn't grow, or they could get dried out from too much heat. Without the plants, the primary consumers would have nothing to eat and die out, causing the same to happen to the secondary consumers, and then the tertiary consumers.

Water: Without water, none of the animals would have anything to drink or bathe in, and the plants would be unable to grow.  Being unable to drink would lead to dehydration, and, if they were unable to bathe, that may increase the amount of bacteria and viruses on them.  If there was too much water, though, plants also couldn't grow because the ground would be too wet, and the animals could drown if there was enough excess water.

Light: Too much or too little light in the forest could cause sleeping and hunting problems for the animals.  If there was too much light, the animals would be unable to sleep when night came, because it would still be light out.  This would cause them to be sleep deprived and they would be more easily caught by predators, and would find it more difficult to do things.  With too little light, they wouldn't be able to hunt for food, as they wouldn't know where they were going.
