Ecology
Ecology is a branch of biology that studies the interactions of living things with each other and with the environment
Ecology from the Greek oikos, "home," and logos, "to study"

Sciences related to Ecology
The science that studies the distribution of plants and animals is called biogeography
The science that studies abiotic and biotic factors of fresh water is limnology
The branch that studies the biotic and physical conditions of marine ecosystems is called oceanography
The ecology of radiation is called radiology
The ecology of space is called space ecology

The environment includes abiotic components (nonliving chemical and physical factors) such as temperature, light, water, and nutrients
The environment includes abiotic components (nonliving chemical and physical factors) such as temperature, light, water, and nutrients
Biotic components (living) such as plants, animals, fungi-all the other organisms

The variety of living things on earth is affected and determined by sunlight, temperature, pressure, moisture, and air movements, which are all together called climatic factors

The energy source for all organisms in nature is light
The energy source for all organisms in nature is light
The reproduction, migration, and pigmentation of various organisms are all affected by light
Light is essential for photosynthesis, thus it affects plants

Temperature
All life on earth needs heat to survive
The source of this heat is sunlight
Animals are placed into two groups according to the relationship between their body temperature and the air temperature:
- poikilothermal animals (without constant body temperature)
- homoiothermal animals (with constant body temperature)

Temperature
Invertebrates, fish, frogs and reptiles are poikilothermal animals – their body temperature depends on environment
Homoiothermal animals are birds and mammals

Water
Plants are placed in three groups according to their water needs:
Hydrophytes - grow where water is always available, ex: water lily and elodea
Mesophytes – grow where water availability is intermittent, ex: clover,  lilac
Xerophytes - grow where water is scarce most of the time, ex: cactus

Soil Factors
Soil is very suitable to life for bacteria, fungi, viruses, algae, and protozoans
Microorganisms are especially abundant in soil rich in organic wastes
The dominance of a microorganism in a certain area is determined by environmental conditions

Soil factors
Soil, water, air, organic and inorganic molecules are very important for plant growth
The ratios of these 4 groups in the soil are as follows:
- Minerals (Ca, Mg, P, N): 45%
- Organic molecules (plant and animal residues): 5%
- Air: 25%
- Water (soil water with dissolved salts): 25%

Organisms contain very important and vital minerals 
Organisms contain very important and vital minerals 
The most important ones are N, P, K, Ca, S, Fe and Mg
Deficiency of these causes serious problems in living things 
For example, Ca is an element used by all organisms
Calcium is a component of animal endo- and exoskeletons, and is necessary for muscle contraction and blood clotting

Biotic components usually include:
Biotic components usually include:
Producers - plants
Consumers - animals, they depend upon producers for food.
Decomposers - fungi and bacteria, they break down chemicals from producers and consumers (usually dead) into simpler form which can be reused
