This is a picture of a nest up in a tree for a bird or also known as a Habitat. Habitats are for organisms to live in and have food near them.
These four pictures represent the Biosphere. The Biosphere is all of the Earth that supports life like the crust, the atmosphere, and the waters that cover the Earth. The dirt on the Earth shows the thin layer of crust on the Earth, the horses grazing shows the life that is being supported, the sky represents the atmosphere around the Earth, and the pond represents the waters that cover the Earth.
The Ecosystem is all of the organisms living in an area, as well as nonliving parts in that environment. This is a picture of all of the cattle population in a pen and you may not see ,but there are sparrows on the far fence waiting to swoop down to eat the grasshoppers. Some of the non-living things in the picture is the dirt or crust.
A Population is all of the organisms of the same species that live in the same area at the same time. This is a picture of a group of ant hills. The ant hills are a Population because there is a group of the same species that live in this area.
A Community is all of the population of all of the species living in an ecosystem. This is a picture of a Community because there is all of the species living in this ecosystem. The different species in this picture is a dog, five cattle and you may see there is a cat in the alley way to your left.
Biotic refers to all living things in the ecosystem. These three pictures are all Biotic. The grass is Biotic because it is living, the fox is Biotic because it is alive and is moving, the green plant is Biotic because it is living and producing oxygen and sugars.

Abiotic is associated with nonliving organisms. The three pictures represent all Abiotic. The oxygen and carbon dioxide are not living, so therefore is Abiotic, the water running through the drain is Abiotic because there are no living organisms in water, and the crust or dirt has no living organisms in it, so it is Abiotic.
A Producer is a plant that goes through the process called photosynthesis. These two pictures are producers. The tomato plant in the picture are producers because not only they are growing plants but they are taking in carbon dioxide and go through the process called photosynthesis and make their own food and release fresh oxygen. The whole garden is a produce ,not only are they growing vegetables ,but they are taking in carbon dioxide and going through the process of photosynthesis just like the big Cotton Wood tree behind is doing the same process and then they are letting out fresh oxygen.
