पारिस्थितिकी तंत्र || Lecture-2 #RANKERS EDUCARE #12thupboard #boardexam #12thgradebiology Organisms Populations Communities Biomes Let us discuss the first two levels of organizations, organisms and population Population Growth Models The population growth models include: Exponential Growth: With the limited supply of food, the population follows exponential growth. Logistic Growth: When the resources are finite and become limited sooner or later, population growth is said to be logistic. Population Interactions This refers to the interaction between different populations. There are various modes of population interaction. These include: Predation This is a type of interaction in which an organism kills and feeds on another organism. The one who kills is known as the predator and the one who is killed is the prey. Competition This is the type of biological interaction between different animals or species in which both are harmed. Parasitism Parasitism is a type of interaction between species in which the parasite lives inside the body of another organism and cause harm to it. Commensalism In this type of interaction, one organism benefits while the other is neither benefitted nor harmed. Mutualism In this type of interaction, both the species or organisms are benefitted from each other. Learn more about organisms and populations by registering at BYJU’S website.
