Biotic and Abiotic Factors Flashcards
Biotic Factors
Produces
Consumers
Decomposers
Abiotic Factors
Soil
Water
Light etc.
Producers
Plants use sun energy to produce food
Use light, eater and CO2 to make starch
Consumers
Organisms not able to make own food -> eat other organisms
Classification of consumers:

3 Types of soils
sandy soil
loamy soil
clay soil
Silt
very fine particles of rock
Humus
sticky substance formed from decomposers breaking down dead organic material
Water holding cpacity
different soils hold different amounts of water
important for plant growth
Water holding capacity: Clay
Holds lots of water
Water holding capacity: Sand
holds very little water
Water holding capacity: Loam
Holds moderate amount of water
