Name: Sohaib Abufarha Grade: 9 th boys Date: 5/1/12 My topic question is:
What are food chains and their components? O What is a food chain? This is food and this is a chain. Think of a food chain as a chain and at each rings’ end, there is food that is a meal for the next ring. Like this:
O The food chain is a pathway of energy flow. It all starts out with when light energy is transformed by plants into organic nutrients.
Without sunlight, we wouldn’t exist as well as the ecosystems. The plants that perform the role above, are called producers b’cuz they produce the meals for other animals. Plants take in light energy and turn it into nutrients that can be eaten by other animals. PRODUCER
SUN PLANTS/PRODUCER The cow eats the plants and now contains the energy from the plant The baby later eats the cow and now intakes the energy.
After the plants produce the food, an organism eats the producers. These organisms are called consumers or heterotrophs. In the food chain in the previous slide the consumers are 1) THE COW AND 2)DA BABY
HERBIVORES: they are organisms that eat and survive on plants CARNIVORES: they are organisms that eat and survive on herbivores and other carnivores. I AM A CAAARRRR NNNNIIIVVV VOOOORRR EEEE MMMMM MMOOOO OOOOOO O
These living things consume wastes and dead bodies of all the other organisms DECOMPOSERS RELEASE THE ENERGY BACK INTO THE ENVIRONMENT
These are also other organism that feast on dead bodies and other dead organisms in the environment. HEY, I’M A SCAVENGER. WE R NATURE’S CLEAN—UP--- CREW…..OR SANITATION EVEN AFTER SCAVENGERS FEAST ON DEAD ANIMALS AND BODIES, DECOMPOSERS STILL HAVE 2 DO THEIR JOB. SCAVENGERS R NOT DECOMPOSERS
NOW AFTER ALLL THAT INFORMATION, THE NEW FOOD CHAIN WOULD LOOK LIKE THIS : SUN PLANTSHERBIVORES CARNIVORESSCAVENGERS DECOMPOSERS
FOOD WEBS ARE VERY SIMILAR TO FOOD CHAINS. THEY ARE DIAGRAMS THAT COMPLEX FEEDING RELATIONSHIPS BETWEEN PRODUCERS, CONSUMERS, AND DECOMPOSERS. IT’S A PIECE OF CAKE !
SORRY, BUT NO. AS WE LEARNED EARLIER, PLANTS TURN SUNLIGHT INTO ORGANIC NUTRIENTS. THIS IS DONE WITH THE HELP OF THE CELL ORGANELLE, THE CHLOROPLAST. PLANTS ARE THE ONLY LIVING THINGS THAT HAVE CHLOROPLAST AND SO WITHOUT THEM, NO FOOD CHAINS
