Environmental resistance in ecology

The form that the environmental resistance takes depends on the species in question.

Here are the main factors that limit population growth

• lack of food or water
• lack of light
• lack of oxygen
• predator and parasites
• Disease
• lack of shelter
• Accumulation of toxic waste e.g. CO₂ and nitrogenous waste
• stress in some case overcrowding may excess stress leading to abnormal behaviors. E.g., Female rats kept in capacity at a high population density show a breakdown in normal maternal behavior, failing to build adequate next and abandoning their young ones.
