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?
