This week in science class we were learning about the ecosystem. So we went for a walk to see what was an ecosystem. We took pictures, and when we got back to class we had to make a list about what we saw. We had to put them in groups of abiotic and biotic. In the Ecosystem there needs to be abiotic and biotic objects like a rock and a tree. While we were on our walk we saw a little plant growing on the side of the road, and that showed an ecological succession because it is a predictable change because we now its going to grow bigger. We saw a lot of rocks, and they had micro-organism’s because they have germs all over them some harmful, and some that are not harmful.We saw biospheres because a biosphere is  living beings living together in their environment. We saw plants, and they play a big part in photosynthesis because they are a part of the process that converts carbon dioxide in to organic compounds especially sugars,using the energy from the sunlight. We saw animals and flies which can be a scavenger because scavengers play an important role in the ecosystem by giving to the decomposers of dead animal remains.  Decomposers complete this process, by eating or taking in the remains left by scavengers.We saw animals and that reminded me of bioaccumulation because when an animal eats another animal and the animal it ate was contaminated then that animal is contaminated then its babies will be contaminated. 🙂  😀
