Ecological Pyramid - Types, Limitations And Importance-Fab study

WHAT IS ECOLOGICAL PYRAMIDS?

An ecological pyramid may be a graphical representation of the connection between the various living organisms at different trophic levels. It was given by G.Evylen Hutchinson and Raymond Lindeman.

It are often observed that these pyramids are within the shape of actual pyramids with the bottom being the broadest, which is roofed by rock bottom trophic level, i.e., producers. The next level is occupied by the next trophic level, i.e., the primary consumers and so on.

All the calculations for construction of those sorts of ecological pyramids must take under consideration all the organisms during a particular trophic level because a sample space of a couple of numbers or a couple of species will find yourself giving an enormous level of errors.



Types of Ecological Pyramid

Three sorts of ecological pyramid exist. they're as follows:

Pyramid of Numbers
pyramid of biomass
Pyramid of energy



Pyramids of numbers


In this sort of ecological pyramid, the amount of organisms in each trophic level is taken into account as A level within the pyramid. The pyramid of numbers is typically upright apart from some situations like that of the detritus organic phenomenon , where many organisms prey on one dead plant or animal.

Pyramid of Biomass

In this particular sort of ecological pyramid, each level takes under consideration the quantity of biomass produced by each trophic level. The pyramid of biomass is additionally upright apart from that observed in oceans where large numbers of zooplanktons depend upon a comparatively smaller number of phytoplanktons.

Pyramid of Energy

Pyramid of energy is that the only sort of ecological pyramid, which is usually upright because the energy flow during a organic phenomenon is usually unidirectional. Also, with every increasing trophic level, some energy is lost into the environment.

Importance of Ecological Pyramid




The importance of ecological pyramid are often explained within the following points:

They show the feeding of various organisms in several ecosystems.
It shows the efficiency of energy transfer.
The condition of the ecosystem are often monitored, and any longer damage are often prevented.



Limitations of the Ecological Pyramid




More than one species may occupy multiple trophic levels as just in case of the food cycle . Thus, this technique doesn't take under consideration food webs.
The saprophytes aren't considered in any of the pyramids albeit they form a crucial a part of the varied ecosystem.
These pyramids are applicable only to simple food chains, which usually don't occur naturally.
These pyramids don't deliver any concept in reference to variations in season and climate.
They do not consider the likelihood of the existence of an equivalent species at different levels.

THALLUS ORGANIZATION IN FUNGI ~ Fab Study

  Thallus organization in fungi  Basically, thallus are divided in to two types.  1. Unicellular  2. Multicellular   1. Unicellular thallus:-     Unicellular organization occur in  some fungal groups. The most widely known are the yeast. Unicellular organization can be found in several fungi with motile zoospores in their life cycles. In Kingdom Fungi only the chytrids have both sexual and asexual motile flagellar cell which are generally posterior whiplash opisthokonts.    Source Wikipedia    2. Multicellular thallus:-   Multicellular  fungi reproduce by making spores. Mold is a multicellular fungus. It consists of filaments called hyphae that can bunch together in to structure called mycelia.    Source Wikipedia      Hypha-   Fungus body made of tiny filaments called hyphae. The group of hyphae is called mycelium. Hyphae are three types.  1. Uninucleate  2. Binucleate  3. Multinucleate     Septa-   Septa are two types.    1. Simplepore-  Ex- Ascomycotina     Source Wikipedia      2.D

HUTCHINSON SYSTEM OF CLASSIFICATION ~ Fab Study

 Hutchinson was a british botanist in royal botanical garden kiwi. He proposed a phylogenetic classification in his book "Family of flowering plants". The last edition of this book was printed in 1972.    (Source wikipedia)   Hutchinsion gave some rules to determine the primitive of plants. These rules are also known as principle of phylogeny. These are 24 principle. The classification is based on principle of phylogeny was suggested by john Hutchinson in his volume 2 in 1969. He published evolution and phylogeny of flowering plants.  PRINCIPLE OF PHYLOGENY    Evolution is both upward & downward.   Evolution is does not necessary involved all organ of the plant at a time.   Evolution has been generally consistent.   Tree & shrub are more primitive than herb.   In one family and genera the tree and shrub are older than climbwords.   Perrenial are primitive than binnial.   Aquatic flowering plants are drive from terrestrial.   Collateral vascular bundle arising in a pri

Food chain and food web





















  FOOD CHAIN   The transfer of food energy from the producers through a series of organisms with repeated eating and being eaten, is known as food chain.   The solar energy is traped in the ecosystem by the green plants and produce energy rich carbohydrates. These green plants are known as primary producers. The green plants are eaten by plant eaters also called primary consumers.   Herbivores  are in turn eater by meat eaters also called secondary consumers. Secondary consumers in turn may be still eaten by other carnivores which are known as tertiary consumers. After decay of both plants and animals simpler compounds are being released into the atmosphere due to the activity of deco posers which are re utilized by green plants.     In nature we generally distinguish two types of food chain  ----- Gazing food chain and detritus food chain.     Example-  A food chain in grassland ecosystem starts with grass and goes through grasshopper , the frogs , the snake and finally the Hawks.
