How The Biotic and Abiotic Factors work together in the Forest

• How do the biotic and Abiotic factors work together?

• If there is no soil, the grass won’t survive.• If there’s no trees, there will not be fresh oxygen.• If there’s no water, the animals won’t be able to

survive.• If there’s no oxygen, there won’t be any animals

in the forest.

Dangers to the ecosystem

• Danger to the ecosystem are hunters because if there are too many hunters in the forest, too many animals will be killed.

• It is not good to to put garbage in the ecosystem because if one animal eats the garbage, the animal will get sick and might not be able to survive.

What if there’s an interruption in the food chain

• If there’s to many hunters in the forest then lots of animals will die in the food chain. For example, if the hunter catch lots of deer, the bears won’t have any thing to eat and the bears will have to leave to another forest and it isn’t good for the forest and the animals.

Interesting fact about the forest ecosystem

Trees and plants are very important to the world and they keep are ecosystem healthy.

Scientist believe that there may be millions of animals in the forest and there are insects also and other animals.

There are wild animals in the forest and some animals are very dangerous.
