Forest ecosystem is the best example of terrestrial ecosystems. It consists of both biotic and abiotic components: (a) Abiotic components: The abiotic or nonliving components are soil, moisture, air and sunlight. (b) Biotic Components: The biotic components are the producers, consumers and decomposers. (i)Producers: The green plants found in the forest are the producers which utilize sunlight for making food. Trees, grass, shrubs , herbs lichens and mosses also act as producers in a forest ecosystem. ii) Consumers: These are available in plenty in forests-which consume the producers as their food. These are grass hoppers, rabbit, deer, monkey, birds, and other wild herbivores animals consuming plants as food. All these are called primary consumers. The secondary consumers live on the primary consumers and are carnivores in nature They are wolves, pthores, jackals etc. The lions, tigers, hawks and eagles are the tertiary consumers who live on by consuming secondary consumers as food. (iii) Decomposers: The bacteria and fungi which live on the dead bodies of produces and consumers in forest in ecosystem and convert complex organic compounds into simple inorganic compounds and elements. The micro-organisms act as decomposers. 8 Reply Share Share Share on Facebook Share on Twitter Share on LinkedIn Share on WhatsApp Ananthu007 Thanjavur, India 22 Questions 201 Answers 1 Best Answer 181k Points View Profile Ananthu007 Administrator Advanced Badge 3 2020-07-18T14:05:01+05:30Added an answer on July 18, 2020 at 2:05 pm I have attached a link where you can find complete information 👇 https://www.google.com/url?sa=t&source=web&rct=j&url=https://en.m.wikipedia.org/wiki/Forest_ecology%23:~:text%3DA%2520forest%2520ecosystem%2520is%2520a,forest%2520ecosystem%2520is%2520very%2520important.&ved=2ahUKEwjOhfGUstbqAhW1zDgGHaCSBcwQFjANegQIDRAx&usg=AOvVaw0JijRtTTiF_GP7ZwnGzYII 5 Reply Share Share Share on Facebook Share on Twitter Share on LinkedIn Share on WhatsApp modelo 1 Question 28 Answers 2 Best Answers 965 Points View Profile modelo Expert 2020-07-12T19:51:57+05:30Added an answer on July 12, 2020 at 7:51 pm Forest Ecosystem : A forest ecosystem is a functional unit or a system which comprises of soil, trees, insects, animals, birds, and man as its interacting units. A forest is a large and complex ecosystem and hence has greater species diversity. Structural Features of the Forest Ecosystem The two main structural features of a forest ecosystem are: 1. Species composition: It refers to the identification and enumeration of the plant and animal species of a forest ecosystem. 2. Stratification: It refers to the vertical distribution of different species which occupy different levels in the forest ecosystem. Every organism occupies a place in an ecosystem on the basis of source of nutrition. For example, in a forest ecosystem, trees occupy the top level, shrubs occupy the second and the herbs and grasses occupy the bottom level. Components of a Forest Ecosystem The components of a forest ecosystem are as follows: 1.Productivity The basic requirement for any ecosystem to function and sustain is the constant input of solar energy. Plants are also the producers in a forest ecosystem. There are two types of productivity in a forest ecosystem, primary and secondary. Primary productivity means the rate of capture of solar energy or biomass production per unit area over a period of time by the plants during photosynthesis. It is further divided into Gross Primary Productivity (GPP) and Net Primary Productivity (NPP). GPP of an ecosystem is the rate of capture of solar energy or the total production of biomass. However, plants also use a significant amount of GPP in respiration. Thus, NPP is the amount of biomass left after the utilization by plants or the producers. We can hence say that NPP is the amount which is available for the consumption to herbivores and decomposers. Secondary productivity means the rate of absorption of food energy by the consumers. 2. Decomposition Decomposition is an extremely oxygen-requiring process. In the process of decomposition, decomposers convert the complex organic compounds of detritus into inorganic substances such as carbon dioxide, water and nutrients. Detritus is the remains of the dead plant such as leaves, bark, flowers and also the dead remains of the animals including their faecal matter. The steps involved in the process of decomposition are fragmentation, leaching, catabolism, humification and mineralization. In the process of fragmentation, detritivores break down the detritus into smaller particles. In the process of leaching, water-soluble inorganic nutrients descend down into the soil and settle as unavailable salts. Under the process of catabolism, bacterial and fungal enzymes reduce detritus into simpler inorganic substances. Humification and mineralization processes take place during the decomposition of soil and not detritus. The process of humification leads to the accumulation of humus which undergoes decomposition at a very slow rate. In the process of mineralization, the humus gets further degraded by microbes and inorganic nutrients are released. 3. Energy flow Energy flows in a single direction. Firstly, plants capture solar energy and then, transfer the food to decomposers. Organisms of different trophic levels are connected to each other for food or energy relationship and thus form a food chain. Energy Pyramid is always upright because energy flows from one trophic level to the next trophic level and in this process, some energy is always lost as heat at each step. 4. Nutrient Cycling Nutrient cycling refers to the storage and movement of nutrient elements through the various components of the ecosystem. There are two types of Nutrient cycling, gaseous and sedimentary. For Gaseous cycle (i.e. nitrogen, carbon), atmosphere or hydrosphere is the reservoir whereas for the sedimentary cycle (i.e. phosphorus) Earth’s crust is the reservoir. I hope you understand. 0 Reply Share Share Share on Facebook Share on Twitter Share on LinkedIn Share on WhatsApp Sathish(sk) Thanjavur, India 9 Questions 18 Answers 0 Best Answers 1k Points View Profile Sathish(sk) Expert 2020-07-12T19:47:49+05:30Added an answer on July 12, 2020 at 7:47 pm A forest ecosystem is the one in which a tall and dense tree grow that support many animals and birds. The forests are found in undisturbed areas receiving moderate to high rainfall. The forest occupies only 19% of its total land area. 0 Reply Share Share Share on Facebook Share on Twitter Share on LinkedIn Share on WhatsApp Leave an answerLeave an answerCancel reply Attachment Select file Browse Featured image Select file Browse Add a Video to describe the problem better.
