Ecological factors are made up of two factors they are the biotic and abiotic factors.

Abiotic Factors
This is made up of the climatic and physiographic factors.
Climatic factors are made up of the physical and chemical factors.
Physical Factors
They include temperature, rainfall, humidity, light intensity, wind and pressure.
Chemical Factors
They include oxygen, nitrogen, water, carbon (iv) onside and mineral salts.
Physiographic Factors
This factor is made up of edaphic and topographical factors.
Edaphic Factors
Edaphic factor include the water content of the soil, the degree of acidity or alkalinity of the soil like the PH, organic content of the soil, availability of nutrient in the soil, the nature of the soil profile and the texture of the soil.
Topographic Factors
This is just about the nature of the soil, including the shape of the land, the attitude, erosion and the drainage of the soil.
Biotic Factors
When we talk about biotic factors, we are talking about the activities of the organisms are concerned primarily on plants and animal relationship, while you also know that habitat is a place where an organism lives.
Ecological Factors Affecting Only Aquatic Habitats
They include salinity, Density and viscosity, Turbidity, Depth of water, water current, Tides and waves, and Dissolved oxygen.
When we talk about salinity we are talking about the salt content, every sea water on earth has a great quantity of salt embedded in it while in fresh water, they have little or no salt content in them. Hence different organisms exist in each of them.
Density And Viscosity
Organisms here, have the ability to float in water because their density is low
Turbidity thus reduces the visibility of the organisms in water because the water is turbid, hence they prefer living at a greater depth of clear water.
Depth of Water
Ponds and streams are usually shallow and not too deep, hence sunlight is able to penetrate deep down, but this cannot happen in deep sea waters. The ponds and the streams are regarded as fresh-waters and because they are freshwaters, green plants can grow throughout their depth as well as animals that feed on them. In this regard a food chain is formed and in every food chained formed there is a flow of energy.
Water Current
The greater the current in a sea the greater the rate at which it will improve the transparency, the air circulation, the circulation of nutrients, and temperature.
Because of the high tides and waved in the sea current transparency, air circulation, nutrients and temperature and been circulated.
Organisms are able to tolerate small PH hence mollusks tend to be absent in waters that the PH is less than 6.
Dissolved Oxygen
In every aquatic habitats, there is a certain degree at which dissolved oxygen gets into the water. You have more oxygen concentration at the top of the waters, but as you go deep inside the waters, the oxygen content is been reduced, hence you find out that oxygen is very important for respiration in the life of aquatic organisms.
Ecological Factors Affecting Only Terrestrial Habitats
They are topographic and Edaphic factors.
Topographic Factors
This is about the distribution of vegetation and animals in that bahitat.
Edaphic talks about the nature and importance of soil distribution in an area. If the soil is lateritic in nature, it will only support a grass land vegetation, while the loamy soil, will only support tropical forest. In a situation like this, the vegetation determines the kind of Animal distribution that will live in that type of habitat.
Ecological Factors Common To All The Habitats
They are temperature, rainfall light, hydrogen concentration, wind and pressure.
Temperature has played a greet role in the life of organisms because it is with temperature it can maintain life.
Rainfall affects the type of vegetation and distribution. An annual rainfall of 1600mm which brings about equatorial forest that supports plenty of animal life.
Light influences the distribution of plants and animals in each zonation. As for plants they need light for photosynthesis.
This varies with depth and altitude some organisms are at a particular depth in water and pressure also influences their distribution.
