وانا بساعده

لاااااااااااااااااااا مااا بدي أحكيلك

انا بدي
بليز

هلا والله

انا اريد براجرف عن food chain
نزلي بالورد

The food chain comprises all living things and is a true reflection of their interdependence and the






complex balance of life. If one animal's source of food disappears, such as from over-fishing or hunting, many other animals in the food chain are impacted and may die.
Breaking one link on the chain means all of the organisms above that link are in threat of extinction (like the domino effect). Since the food chain provides energy that all living things must have in order to survive, it is imperative that we protect it.
Why should I be aware of this?

A significant portion of the Pacific Ocean, twice the size of Texas, is full of plastic. Some of these minuscule pieces of plastic are so small that they are barely visible to the eye. As they swirl in the seas and oceans, they resemble fish food and are eaten by the small fish. The plastic thus enters the food chain.
Evidences of plastic's entry into the food chain were seen when dead bodies of a large number of seabirds that had been washed ashore were found to contain plastic: things like bottle caps, cigarette lighters, tampon applicators, and colored scraps. Apparently these resemble baitfish to the seabird. Scientists say these toxins cause obesity, infertility and other problems amongst humans.
How does this affect me?

In recent times, directly or indirectly man has caused the maximum damage to the food chain. He has hunted animals, razed forest for farming and development, and wreaked havoc everywhere. This adverse impact on the food chain might affect our health, the environment and our planet.
When we spray pesticides, we not only put the food chain in danger, but also affect out health by introducing chemicals in our food.
All about food chain

The food chain consists of four main parts:
Sun -- The sun is the source of energy for all activities on the earth.
Producers -- This includes all plants, which harness the energy of the sun and make their own food.
Consumers - These include all organisms that cannot manufacture their own food and eat food manufactured by something else. While herbivores are primary consumers and the second largest biomass in an ecosystem, carnivores or animals that eat the herbivores make up the third largest biomass, and are also known as secondary consumers. Consumers include
herbivores --animals that eat plants.
carnivores -- animals that eat other animals.
parasites --animals that live off of other organisms by harming it.
scavengers -- animals that eat dead animal carcasses.
Decomposers: These mainly comprise bacteria and fungi that convert dead matter into gases such as carbon and nitrogen to be released back into the air, soil, or water. Without decomposers, the earth would be covered in trash. Decomposers also recycle the nutrients so that it can be used again by producers.
XXXX the sea and the land have a complex food chain.
On Sea

All sea creatures rely on other sea creatures for food. At the bottom of the food chain here are the sea plants, krill and plankton. These are eaten by many types of fish and animals such as the snail, shrimp, jellyfish, and sea star. These small animals and fish in turn become food for larger fish, such as the tuna and mackerel, which are then eaten by larger fish and animals, such as the shark and dolphin. Sharks are much needed to maintain the balance of the marine ecosystem. However, they are killed for food and other things.
On Land

On the land plants or bugs are eaten by smaller animals who in turn are eaten by larger animals. At the top of the food chain on land are humans who eat many of the plants and animals on earth. A break in the food chain can impact everyone, humans also. To understand the food chain in the wild, take the example of the zebra and the grass. The zebra eats the grass. Larger predators like the lion eat the zebra.
Food chain and the environment

Air Pollution

Human activity cause air pollution and lead to global warming. Apart from increasing the sea levels, rise in earth’s temperatures can cause other alterations in the ecology, including modifying the quantity and pattern of rainfall -- which can have its own ramification on the food chain.
Lower agricultural outputs, glacier melting, lesser summer stream flows, genus extinctions and rise in the ranges of disease vectors are likely to be the other consequences. Global warming has already made species like golden toad, harlequin frog of Costa Rica extinct and a number of species are threatened with extinction.
The rise of carbon dioxideemissions and the resultant climate warming from the burning of fossil fuels are making oceans warmer and more acidic which in tuen are damaging coral reefs, the world's most diverse marine ecosystem.
Plastic pollution

The plasticpollution is not just a cause of alarm because it is not biodegradable but it is also making its way into the food chain. Its obvious victims include dead seabirds that have been found on shores, their stomachs full of small plastic items such as bottled water caps, cigarette lighters, tampon applicators, and colored scraps that, to a foraging bird, resemble baitfish. These small plastic waste items are not just affecting sea birds but the entire marine foodchain from whales down to zooplankton. There is a growing and disturbing proof that we are ingesting plastic toxins constantly, and that even slight doses of these substances can severely disrupt gene activity.
