WRITE 50 WORDS FOR THE COMPONENTS OF THE ECOSYSTEM.
Answers
An ecosystem is not entirely a biological entity. The biological or biotic components of an ecosystem include both living organisms and products of these organisms. Thus microbes, all categories of plants and animals as well as their waste products are included in the ecosystems.
The non-biological or abiotic components include climatic and edaphic features, in particular climatic components like sunlight, temperature, air and water supply along with soil component such as soil nutrients which are very important contributing factors of ecosystem operation.
The biotic components are broadly categorized as producers, and consumers of different classes viz. herbivores (animals that eat plants), carnivores (animals that eat flesh of other animals), omnivores (animals that consume both plants and animals as available) and lastly scavengers (animals that eat dead plant and animal matters).
In addition there are decomposer classes, which include mostly saprophytic organisms that help in nutrients and element recycling process.
Decomposers:
They are heterotrophic organisms that feed solely on dead organic matter, i.e., saprophytes. The bulk of the saprophytic decomposition is carried out by bacteria, fungi and protozoans. Imagine that a piece of organic Utter falls to the floor of a forest.
In a typical sequence, microscopic bacteria or fungi will excrete chemicals, called enzymes, that break down the complex chemical compounds in the object Some of the breakdown products are absorbed as food, whereas others are left behind.
These serve as a food supply for other organisms that carry the decomposition one step further. Eventually the waste products of the final line of decomposers are energy-poor mineral nutrients that are reabsorbed, and thus recycled, by plants.
