This week in science: Energy Transfer

This week in science we learned about Food chains. a food chain shows the transfer of energy from one organism to another. a food chain also shows animals from dominent to small and defenseless. the top would most likely be the dominent and the bottom will be the defenseless. We also Drew a energy chain or chart. A energy pyramid shows the amount of energy in each trophic level of an organism. Which basicly means it shows the energy giving off by one organism and going into another organism using arrows.
This week in science i learned about my fantasy animal and were its at in the food chain in its biome.
My animal is a herbivore. Which means it only eats producers. A producer is an organism that makes its own food. I also learned what a energy pyramid is. Also i learned how a food chain works like i knew what it was but i really didn't know how it worked. As far as the arrows and the animals go. Like how the animals are lined up in which they get eaten or eat. Also how the arrows point and what they symbolize. I learned that any animal that eats another living organism is called a carnivore.
i Learned what a primary consumer is and a secondary consumer. At that point i guessed what a tertiary consumer was and i was right. a primary consumer is any organism that gets its energy fron producers.
A secondary consumer is an organism that gets its energy from consumers. And a tertiary consumer is an organism that gets its energy from secondary consumers.
This was my energy pyramid when it was almost finished. I put this up because i wanted to show how it looked before and after i finished.
This is the finished energy pyramid. Not my best but i finished.I put this up because i wanted to show the finished copy.
