PyRamID FOoD ChaIN

The producer is th most down part. it is elodea. And elodea gives energy to water beetles and snails. It is the first order consumer. Those beetles and snails gives energy to small fish. The small fishes is giving energy or being eaten by large fishes. And those large fishes is giving energy to platypuses. It is the last order of consumer.

It shaped like pyramid because it the producers is the biggest organism in the pyramid. When the producers is decreasing population, the other organisms is also decreasing. so if the first order consumer eat the producers, the population is also decreasing.

here is another kinds of pyramid food chain

Dear Atsuka,

Your explanation about what is happening with the food pyramid from the Heineman CD is good. I am responding below in CAPITALS to your answers.

DO YOU MEAN THAT THE THE BOTTOM LAYER SHOWS THAT PRODUCERS ARE THE GREATEST (LARGEST) NUMBER OF ORGANISMS? THEY AREN'T THE BIGGEST ORGANISMS, BUT THERE ARE MORE OF THEM THAN THEIR ARE CONSUMERS.

When the producers is decreasing population, the other organisms is also decreasing. so if the first order consumer eat the producers, the population is also decreasing.

GOOD.

I LIKE YOUR PYRAMID. WHY IS THE PYRAMID GETTING SMALLER TOWARDS THE TOP? WHAT IS HAPPENING TO THE ENERGY ORIGINALLY FOUND IN THE PRODUCERS AS YOU GO TOWARDS THE TOP OF THE PYRAMID?

Good luck!
