Population Interaction: Population interaction refers to the way in which different species in a given environment interact with each other, including mutualism (beneficial interactions), commensalism (interactions in which one species benefits and the other is neither helped nor harmed), parasitism (interactions in which one species benefits at the expense of another), and competition. These interactions can have significant impacts on population dynamics and can ultimately determine the survival and distribution of species in an ecosystem.

Types of Population Interaction

There are four main types of population interactions:

• Competition: occurs when two or more organisms compete for limited resources such as food, water, and space.
• Predation: occurs when one organism (the predator) kills and eats another organism (the prey).
• Mutualism: a symbiotic relationship in which both species benefit from each other. For example, bees and flowers have a mutualistic relationship where bees get food from the flowers and the flowers get pollinated.
• Parasitism: a symbiotic relationship in which one species benefits at the expense of the other. For example, tapeworms live in the digestive tract of mammals and consume their host’s food.
