Producers
The plants and animals that live in and around the pond rely on each other for their survival. Plants need carbon dioxide; animals, like this Bullfrog, produce carbon dioxide. Plants produce oxygen, which the animals need to breathe. Plants and animals need energy to survive, as well. The sample food web showed how energy moves from one organism to another. This energy flow happens in all ecosystems, but we need to know where the energy comes from that starts the process. Your first question dealt with plants and deep water. Did you find that plants can't grow in deep water because there isn't enough sunlight reaching the bottom? If you did, then you are right. Plants need sunlight in order to carry out photosynthesis.
Plants are called producers because they undergo photosynthesis and therefore they can produce their own food. Are there any other organisms that can be called producers? Check out Geography4Kids.com and watch the video at Videopedia for the answer and then write it on the Student Activity Sheet in the Question 2 space.
We are starting to piece some information together, but there still isn't enough for us to build the Pond Food Web. Perhaps the Consumers page will give us what we need.
