يلآآ بسم اللهFood ChainsEvery organismneeds to obtain energy in order to liveFoe example,plants get energy from the sun, some animals eat plants, and some animals eatother animals Food chains are the sequence of feeding relationships through whichplants and animals depend on each other for food. Food provides the nutrientsplants and animals need to build and repair their body parts, and the energythey need to grow and function. There are countless food chains involvingdifferent plant and animal species in a variety of habitats all around theworld. Every plant and animal belongs to at least one food chain, and thesechains can be simple or very complex. A Food chain contains two kind of animals , producers and consumersAt the base of the food chain lie the producers. Producers are mainly greenplants and certain bacteria, which convert sunlight into food energy. Above theproducers are the consumers who ingest live plants or other animals.Decomposers, such as, bacteria, molds, and fungi make use of energy stored inalready dead plant and animal tissues. Energy from the Sun[ندعوك للتسجيل في المنتدى أو التعريف بنفسك لمعاينة هذه الصورة]The sun is the primary source of energy for all life. Even living organismsthat seem to flourish in darkness feed on plants, insects, animals, ormicroorganisms that depend on sunlight for their survival. The sun providesenergy that plants can use to make their own food. This is the first step inevery food chain. Natural Food FactoriesAll green plants can do something truly amazing and unique that no otherliving organism on earth can do. They can make their own food energy usingsunlight, air, and water. This process by which plants produce food energy iscalled photosynthesis. The word photosynthesis comesfrom two Greek words. Photo means light and synthesis means putting thingstogether to make something new. Photosynthesis in ActionGreen plants have a special chemical in their leaves called chlorophyllchloroplasts, andallows the leaves to act like miniature solar panels capturing and storing thesun’s energy far more efficiently than anything ever devised by humans. Greenplants use the energy from sunlight shining on their leaves to produce theirown food. Carbon dioxide gas from the air enters through pores in the leaves,and water is absorbed through its roots. Carbon dioxide and water are combinedwith the energy from the sun to create food energy.
which is the substance that makes leaves green. The chlorophyll is found inlittle compartments of green leaves, called the Natural Food EnergyThe foods that plants make using the process of photosynthesis are sugars.These include glucose and fructose, which are converted by the plant intosucrose for storage. Sucrose, glucose, and fructose are found naturally in allplants, and are the basis for all food energy. The sugars that plants produce are stored in the root, leaf, seed, or fruitof the plant. Plants that produce sucrose in the largest quantities are sugarcane and sugar beets and thus are harvested to produce the sugar for commercialand industrial use.
Food Chains & Food WebsDo you like to play games? Ifyou do, you will need energy. Every time you run or jump, you are using upenergy in your body. How do you get the energy to play? You get energy from thefood you eat. Similarly, all living things get energy from their food so thatthey can move and grow. As food passes through the body, some of it isdigested. This process of digestion releases energy.
A food chain shows how each living thing gets its food. Some animals eatplants and some animals eat other animals. For example, a simple food chainlinks the trees & shrubs, the giraffes (that eat trees & shrubs), andthe lions (that eat the giraffes). Each link in this chain is food for the nextlink. A food chain always starts with plant life and ends with an animal.
- Plants are called producers because they are able to use light energy from the Sun to produce food (sugar) from carbon dioxide and water.
- Animals cannot make their own food so they must eat plants and/or other animals. They are called consumers. There are three groups of consumers.
- Animals that eat ONLY PLANTS are called herbivores (or primary consumers).
- Animals that eat OTHER ANIMALS are called carnivores.
