LIVING ORGANISMS FOUND NEAR THE TREE I found many living organisms near the tree, even if the

tree is not in a forest, I imagine that if the tree was in a forest the amount of living organisms will increase.

Living organisms:

Squirrels Ants. Chicharras

Pecho amarillo Pigeon worm

SOIL PROFILE

The soil is most of it very soft, we can find some rocks at the bottom but the majority is soft soil, on the top we can find some dust but is not a big quantity.

From what analysis we can see that there can grow a good vegetation, because the soil ph was of 7, and 7 is a good ph for vegetation.

PH

Ph is very important for the organisms which live in the soil, some ph don’t allow the grown of any tree and also the habitation of animals in it, because it has wastes that are toxic or something that makes the ph unfertile.

Bacteria can not live in a soil ph below 4.7 The ideal ph for my tree would be 6.5, because is a

neutral ph which allow the grown of nutrients and there many animals and bacteria's could also live in.

Some trees need low ph such as lemon trees, other trees need high ph to live in, but the most normal ph is from 6.5 to 7.0

From what I observed before, I can see that the ph for my tree is good, I found worms on the soil and the soil was soft enough to dig a hole.

BIOTIC AND ABIOTIC FACTORS

A= without Bios: life Abiotic: Abiotic factor means something that don’t live. Biotic: the living organisms in a plant environment. Plants can adapt to the biotic and abiotic factors around

them. Biotic and abiotic factors found near my tree that affect

it: Abiotic: Wind Sunlight Soil Temperature Biotic: Leaves Birds Grass Worms Insects

FOREST OBSERVATION

I listened for 1 minute all the biotic and abiotic factors that I cold hear in a forest, also I spend another minute observing to see what could I find, these are the results:

Listen: Crickets Birds, (6 more less) Guacharaca Pellar Observed: Spyders Worms Dragon fly's Pellar Bicho jue Torcasa morada Gavilan Ants Foxes Almost all the birds where on top of the trees, but some

of them where down in the ground.
