Objectives:
* To define Ecology * To differentiate abiotic and biotic components of the ecosystem. * To identify the different types of ecosystem. * To know the different elemental cycles * To understand the importance of the natural habitat and the effects of migration. * To know have an overview of what is food chain and food web * To differentiate renewable from non-renewable resources * To know what is population, migration and their components * To have knowledge on the endemic species and endemism
Ecology (from Greek: οἶκος, "house"; -λογία, "study of"[A]) is the scientific study of the relationships that living organisms have with each other and with their natural environment. Topics of interest to ecologists include the composition, distribution, amount (biomass), number, and changing states of organisms within and among ecosystems. Ecosystems are composed of dynamically interacting parts including organisms, the communities they make up, and the non-living components of their environment. These processes are sustained by the biodiversity within them. Biodiversity refers to the varieties of species in ecosystems, the genetic variations they contain, and the processes that are functionally enriched by the diversity of ecological interactions.
Components
* Biotic - meaning of or related to life, are living factors. Plants, animals, fungi, protist and bacteria are all biotic or living factors. * Abiotic - meaning not alive, are nonliving factors that affect living organisms. Environmental factors such habitat (pond, lake, ocean, desert, mountain) or weather such as temperature, cloud cover, rain, snow, hurricanes, etc. are abiotic factors.
Different Types of Ecosystems * Natural Ecosystem - may be terrestrial (means Desert, Forest, Meadow etc.) and Aquatic like pond, river, lake etc. A natural ecosystem is a biological environment that is found in nature (e.g. a
