The non living physical features of the environment are called ABIOTIC FACTORS

The features of the environment that are alive or were once live are called BIOTIC FACTORS the term Biotic means “living”

The non living physical features of the environment are called ABIOTIC FACTORSABIOTIC FACTORS OFTEN DETERMINE WHICH KINDS OF ORGANISMS CAN LIVE THERE

ABIOTIC BIOTIC

AIR PLANTS

WATER ANIMALS

SOIL MICROORGANISMS

SUNLIGHT FUNGY

TEMPERATURE BACTERIA

CLIMATE DEAD PLANTS AND ANIMALS

Air

The air that surrounds earth is called Atmosphere

Air contains 78% of Nitrogen, 21% of Oxygen, 0.94% Argon 0.03% CO2 and the rest are trace gases

Water

It is essential for lifeOrganisms are from 50%to 95% water

Soil biotic and abiotic factorIs a mixture of mineral and rock particles, the remains of dead organisms,water and air.It´s de topmost layer of earth´s crust and supports plan growth

Is there life in soil?

SunlightIs the energy source for most almost all life on earth via photosynthesis

Elevation

It´s directly correlated with ambient temperature and the existence of life

At higher elevations less temperature because there are less air molecules to be warmed by sun

TemperatureHeat energy provided by sun is very importan Because most organisms can survive only if their body temperature stay within the range of 0°C to 50°C Temperature depends on the amount of sun light that it receives from the sun at it depends on latitude

HomeworkExplain why soil is considered an abiotic and a biotic factor.

Imagine you are hiking on hollydays, the first day you hike in shade under tall trees. On day 2, the trees are shorter and farther apart. On day 3, you see small plants but no trees. On day 4 you see snow.What abiotc factors might contribute to these changes?
