Food chain: examples and description

click fraud protection

food - it is something without which there can live and develop a single living organism.Plants - these are living organisms that can independently create for themselves a meal from nothing.Others feed on what has been created without their participation.

What trophic chain?

biosphere is huge and multifaceted.It includes a variety of creatures.And the wonderful and terrible.But these creatures are related to each other.Sometimes these connections are imperceptible, and sometimes from one species depends on the existence of another.The most obvious link between living beings is the food.Food chains are also called trophic.

plants - are creatures that are capable of photosynthesis.This means that if carbon dioxide, water and sunlight, they can survive.Animals on is not.Because the vast majority of the trophic chain begins with plants.

food chain are different.They are divided into two groups.Those food chain, starting with the producer, called grazing.But there are those that start with waste.For example, animal carcasses.These chains are called detrital.

among living organisms secrete producers, consumers and decomposers.

Producers

Many food chain starting with the producers.That's called all the organisms that produce their own nutrients for themselves.The best-known producers are the green plants, which are capable of photosynthesis.But also it can be attributed to bacteria chemotroph that can do even without sunlight.

consuments

But not all participants in food chains may do the minimum.Most of the need for life that was made by others.These consumers are called by consumers.But among them there is a different type food group.

Some animals eat plants.They also enter the food chain.The trophic level of nenamnogim higher plants.In turn, they too will become someone's dinner.

Those who need meat for life, called predators.This new level.They are forced to go on the hunt to find their own food.In order to get food, they must use all their tricks to track down and catch prey.Each predator has a long list of preferences.This helps different types survive even in the most difficult times.This is especially important now because many species are on the verge of extinction.

Decomposers

food chain and include such unusual organisms are decomposers.These are living beings, which are called "grave diggers of nature."They help waste and corpses decompose into simpler components.Decomposers feed on the fact that no one else is interesting.

corpse or wastes decompose assisted reducers, and called detritus.Because the food chain, which starts so unusual is detrital.

There are many different decomposers.Among them are fungi, bacteria, saprophagous, necrophages and Coprophagia.

saprophages - these are the decomposers that feed on dead bodies of other living beings.Necrophagia also feed on corpses and carrion.Coprophagia feed on organic waste beings.All these organisms are helping to preserve the purity of nature, to make room for a new life and growth of living organisms.While some consider these abominable beings without them it is impossible to imagine a healthy biosphere.

Examples of trophic chains

not easy to study the trophic chain.Examples will help to understand who and who eats.The most familiar is the grazing trophic chain.It begins with plants.So you can start with the cereal.They are included in the list of preferences hares.Rabbits - a consuments first order.Hares feed the wolves.Wolves - a consuments second order.

Mice also like cereals.Mice in the food chain by consumers are the first order.Sometimes the mouse victims urchins.Jerzy - consuments second order.They also can not be sure about their lives, because they hunt foxes.The last will be the third order by consumers.

food chain can be found in the water.You can start with the phytoplankton, which is able to support themselves independently.But they feed on zooplankton.Zooplankton - small food fishes.And they, in turn, become the favorite treat pike.But she, too, could become someone's meal.

longest food chain can be found in the ocean.In these circuits are even consuments fifth and sixth order.Everyone can do a little research.It is very interesting and allows you to better understand the world around us.

detrital food chain do not include so many participants.Usually in their structure - only waste or corpse creature that feeds on them.The most famous decomposers are bacteria and fungi.

food web

food chain are not able to fully reflect the whole life of the biosphere.After all, if we assume that all extinct hares, wolves and foxes do not die.They will just eat other animals, although the number of these predators will be reduced.This natural balance is maintained by the trophic networks.

The same rabbit could eat different plants.He can eat cereals, oats, lichen, clover and more.Wolf can also have a variety of animals, which differ from each other even in size.Trophic chains and networks help to establish the nature of such a balance to creatures able to survive the event that any kind of disappear from the face of the Earth.

food webs sometimes very, very confused.It is not easy to figure out how many animals wish to eat some plants and animals from any hiding any small animal.You can create a wide variety of food webs.They are especially rich where side by side adjacent to a large number of living beings.

world surrounding man, keeps a lot of mysteries and interesting moments.One of them is trophic chains and networks.Carefully thought-out nature of the food chain to help a variety of plants and animals live together in relative peace with each other, to find food for themselves and their young, as well as to clean their environment from what had outlived its time.
