Definition of Food Nets

Many misconceptions about food webs and food chains. Because the two are almost the same, but actually they are indeed interconnected. Then, what makes the food chain and food webs different?

The food chain is a process of transferring an energy that is owned from one organism to another. The food chain has a sequence called trophic. Whereas food nets are a combination of several food chain processes whose cycles or processes have a relationship with each other.

Therefore, it can be concluded that the food chain is part of the food web process or a process of eating is eaten on a more scale. small. And food webs are processes or collections of various food chains with a wider and larger scale and scope.

Nets – food webs are also called resource systems. Naturally, living things will eat more than one variety or type of food.

For example, a squirrel eats seeds, nuts, and fruits. Then, the squirrel is eaten by a raccoon or fox. Foxes can also eat grasshoppers and mice, and so on. Most living things are part of several food chain processes.

Functions of Food Nets

 Functions of food webs

Based on the above understanding and explanation, food webs have several functions. The following are some of the functions of food webs, namely:

  1. Nets – food webs have a function for simplification when understanding the relationships between species
  2. Nets – Food webs in ecosystems have functions and uses to describe direct interactions between species so that the relationships between species are easily distinguished, which are included in transitional species, basal species, and also species of peak predators.
  3. Food webs also have a function to study top-down controls or bottom-up controls in a structure or form of community.

One example of simple food webs based on ecosystems of rice fields is inside grass, water spinach, genjer, ulay, grasshopper, butterfly, rice, snail, frog, rat, worm, snake, bird pipit, etc.

Food Nets

Nets – food webs are like lan from several food chain processes that are put together into one and are interrelated or related. Food webs appear and occur because of living things that consume more than one type or variation of food or living things consumed by other living things.

Nets not only occur in one ecosystem , but it occurs in various kinds of ecosystems. Here are some food nets from various ecosystems such as rice fields, sea, forests, gardens, lakes, rivers and land.

1. Food Nets in the Rice Field

Nets – many food webs occur in various ecosystems, one of which is in the rice fields, where rice fields are one of the habitats inhabited by living things in them.

Various kinds of living things that live there, definitely make food nets so they can maintain their lives. Here is an example of a food net in a rice field:

Rice and trees as producers eaten by rats, grasshoppers and caterpillars. Then, rats are eaten by snakes and eagles. Grasshoppers are eaten by frogs and chickens. Caterpillars are eaten by frogs and chickens.

Then chicken is eaten by snakes and eagles. Frogs are eaten by snakes and eagles. Eagles can also eat snakes. When snakes and eagles die, they will be broken down by decomposing bacteria.

2. Food Nets in the Sea

Nets not only occur in the ecosystem of rice fields, but also occur in the sea. Food nets in the sea are different from food nets in the rice fields, because living things that live inside are also different.

Every living thing will certainly make food webs to extend and maintain its survival. Here is an example of food nets at sea:

 sea food webs

Explanation: seaweed as an autotrophic organism or its own food producer or also called a producer eaten by crabs that are consumers. Furthermore, crabs are eaten by squid which are also consumers. Then, squid are eaten by elephant seals and penguins which are also referred to as consumers.

Then, sea elephant dogs are eaten by whales. Penguin is eaten by whales and also sea leopards are also located as consumers.

Then, phytoplankon which is also an organism that is capable of producing its own food can be eaten by small shrimp and zooplankton. Zooplankton is a bacteria and waste-eating animals or carcasses, usually found in dark areas.

Then, zooplankton is eaten by fish. Small shrimp are eaten by blue whales and fish. Then, the fish are eaten by seagulls and sea leopards. And seagulls are eaten by sea leopards.

3. Food Nets in the Forest

In addition to the rice and marine ecosystems, food nets also occur in forest ecosystems. Just like food nets in other ecosystems, there are also food webs in the forest. Only living things that inhabit them are different.

In the forest there are also many predatory living things such as lions, wolves, or tigers. So that living things like rabbits, goats will be easily threatened. The following is an example of a food web in the forest:

 forest food webs

Explanation: Plants or trees that act as producers are eaten by tikur, rabbits and goats. Usually consumers who are in the first level are herbivorous, but it is possible that it is also an omnivorous species. Then, rats are eaten by owls and jungle cats.

Rabbits are eaten by jungle cats and wolves. Goats are eaten by wolves. Then, the owl is eaten by jungle cats and snakes. Jungle cats are eaten by lions and wolves. A wolf is eaten by a lion. Then, snakes are eaten by eagles and jungle cats. And the eagle is eaten by the lion. And if the lion dies, it will be eaten by decomposing bacteria.

4. Food Nets in the Garden

In addition to the above ecosystems, food nets also occur in the garden ecosystem. Basically all the concepts of nets – food nets are the same, only living beings distinguish them. Food webs in the garden are also almost the same as food webs in the fields. The following are examples of food webs in the garden:

[1945foodnetnets” width=”505″ height=”372″/>

Explanation: Plants as producers or producers of food themselves are eaten by first-level concentrations of grasshoppers, rats, rabbits and birds seed eater. Then, grasshoppers are eaten by spiders. Seed-eating birds are eaten by snakes, eagles and foxes. Then, rats and rabbits are eaten by foxes and eagles.

Then spiders are eaten by snakes and insectivorous birds. Insectivorous birds are eaten by eagles and foxes. Snakes are eaten by eagles. And if eagles and foxes die, they will be eaten by decomposing bacteria.

5. Food Nets on the Lake

Furthermore, food webs also occur in the lake ecosystem. It's almost the same as food nets in the sea, but only living things aren't as much as those in the sea. All must begin with autotroph plants that are able to produce their own food, then eaten by other consumers who live and live on the lake.

6. Food Nets on the River

In addition, food nets are also found in rivers. Just like food webs that occur in lakes and at sea, but food webs that occur in rivers are smaller than lakes and seas, because the ecosystems are only few, not as much as in the sea and on lakes.

7. Food webs on the ground

And food nets also occur on land. Food webs that occur on land, of course, most of the perpetrators are living things on land, such as humans, land plants, and also animals that are on land.

Our discussion this time about the understanding of nets along with its functions and also examples of food nets from various ecosystems. Hopefully this article can be useful. Thank you 🙂
