Carrying capacity of ecosystem

This presentation is on carrying capacity of the ecosystem. Here in the presentation we explained about the ecosystem and it's example. It also explained about the the how population and growth pattern takes place in particular a ecosystem and it's effect on carrying capacity.This presentation is taken by Dr. Sachin mandavgane faculty of chemical engineering VNIT Nagpur as a part of our course in sustainable engineering.

3. What is Ecosystem An  ecosystem is a large community of living  organisms  (plants, animals and  microbes) in a particular area . Ecosystems are of any size, but usually they are in particular places. A lake could be considered an ecosystem.

4. Habitat and Niches Every organism has a habitat and a niche. A habitat is all aspects of the area in which an organism lives . An ecological niche includes all of the factors that a species needs to survive , stay healthy, and reproduce.

5. Population & Growth Pattern Populations grow in predictable patterns. The size of a population is always changing. Four factors affect the size of a population. immigration births emigration deaths

6. Population growth is based on available resources. Exponential growth is a rapid population increase due to an abundance of resources.

7. Logistic growth is due to a population facing limited resources.

8. Carrying Capacity Carrying capacity is the maximum number of individuals of a species that an ecosystem can support . (Or) Carrying capacity = maximum number of organisms that can live somewhere, based on the Food , water and free Space.

9. Carrying capacity graph We can read a carrying capacity graph to predict changes in population size Below carrying capacity = increase Above carrying capacity = decrease Over time, population stabilizes at carrying capacity Time Population size Graph line = Population size at a specific time Dotted line = Carrying Capacity

11. Limiting Factors A limiting factor is an environmental factor that causes a population to stop growing. A limiting factor is an abiotic or biotic factor that restricts the number of individuals in a population. Abiotic Factor The physical components of an ecosystem. Any nonliving part of the environment . Biotic Factor The biological influences on organisms. Any living part of the environment with which an organism may interact.

12. Abiotic Factors that influence carrying capacity Temperature Precipitation Soil composition pH Humidity Salinity Amount of sunlight Availability of nitrogen

13. Biotic Factors that influence carrying capacity All biological aspects of an ecosystem fall into this category. Vegetation composition often determines what species will be attracted to a given area due to food availability . Scientists note that competition, predator-prey relations, mutualism, and host-pathogen interactions are critical to consider when accessing carrying capacity .
