Did you know that there are communities right in your backyard? Do you know that some(1) _______________________ don't have houses, but trees, plants, and shrubs? Well, these communities are part ofecosystems . They are also part of biomes .Biomes are large areas that have similar plants, animals, and other organisms . Organisms are living things that can work independently. Some of these organisms we cannot see with our eyes. However, they are there. Ecosystems are smaller than biomes. They are a (2) _______________________ of plants and animals that live in an environment.
There are many (3) _______________________ on Earth. However, we will only talk about four. They are forests,(4) _______________________ , deserts, and tundras. The animals and plants in these biomes need to (5) _______________________ to the environment. Each biome has different types of water, soil, and climate.
Forests are trees and other plants that cover a large area. These trees and plants grow in groups that are very(6) _______________________ . Depending on the climate, different types of trees and plants grow in the forest. There are tropical rainforests, tropical dry forests, cold climate forests, and temperate forests. Temperate forests are found in the eastern United States. These forests have cold winters and warm summers. You can tell you are in a (7) _______________________ forest if the leaves change colors in the fall. Cold climate forests have trees that have cones. You would find pine, fir, and spruce trees in these areas. These forests are found in the mountains.
Tropical forests are found in different areas of the world. Tropical dry forests are found in parts of Australia and Central America. They have high temperatures. They also have very little (8) _______________________ . Tropical rainforests are the opposite. They have a lot of rain. Some of these forests are found in Africa, South America, and Asia.
Grasslands are areas that are covered with grass and very few trees. You know them as prairies in the United States. There are very hot summers and very cold winters in (9) _______________________ areas. Grasslands have some rain. However, the rain is not enough for trees to grow there.
Deserts are the driest places on Earth. They have very little rain (10) _______________________ the year. The plants that are in the desert have to survive the low amount of rain. You may see cacti in deserts. The U.S. has a desert in California. It is called the Mojave Desert (Mo-ha-vee). The Sahara Desert in Africa is the largest desert on Earth.
The last (11) _______________________ is tundra. A tundra is a frozen prairie.

FOOD WEB

1 Every living thing needs food. People enjoy eating food. But that's not the reason we eat. People eat to stay alive. We need food so we can grow. We need food for the energy to do things. Our bodies change our food into energy. We use energy when our hearts beat. We use energy when our lungs breathe. We need energy to stay alive. We use the energy to walk, talk, read, sleep, think, and dream.
Assignment= Please copy into your journal and complete this graphic organizer from the reading above
2 Just like us, animals of all kinds need food, too. Food and its energy move from one living thing to another. In the ocean, big fish eat little fish. Little fish eat smaller animals or plants that live in the ocean. Food and energy move in a path we call the food chain. It's usually not a straight path. There can be links between many different things. If we draw a picture of the path that food's energy moves in, it begins to look more like a spider web. So the food chain is often called the food web, too. A food web is a diagram or drawing that shows how living things get energy.
Assignment= Please copy into your journal and complete this graphic organizer from the reading above
3 The food of almost every living thing begins with sunlight. Green plants can use sunlight to make their own food. Even plants that live in the ocean do this. Some of the smallest living things in the ocean are algae. They are so simple they are not even called plants. Algae don't have roots or stems. They don't even have true leaves. Many of them can't be seen without a microscope. Just because they're so small we can't see them doesn't mean they aren't important. These tiny, floating living things are very important! They use sunlight to make their own food. As they do this, they make oxygen for us and all animals on Earth to breathe.
Assignment= Please copy into your journal and complete this graphic organizer from the reading above
4 Algae are food for tiny little floating animals. Together the floating algae and animals are called plankton. Plankton is food for all kinds of animals that live in the ocean. Krill are small shrimp-like animals that live in the ocean. Krill eat plankton. Many animals eat krill. Let's say a seal eats the krill. Then a killer whale might come along and eat the seal. If we were drawing this food chain, we would start with sunlight. Plankton would be the next link in the chain. Then krill comes next because krill eat plankton. The seal would be the next link. Then the killer whale is next. We say the killer whale is at the top of the food chain.
5 Sooner or later the killer whale will die. At least some of its body will sink to the ocean floor. Tiny living organisms will feed on the remains. The food and energy stored in the killer whale's body will now go to feed the tiny organisms, and the cycle of the food chain will start over.

6 But krill eat other things besides plankton. And killer whales don't just eat seals. Most animals don't just eat one type of food. Most animals aren't just eaten by one type of predator, either. Predators hunt, kill, and eat other animals. The animals they hunt are calledprey. Carnivores are animals that eat the meat of other animals. Herbivores are animals that eat only plants. Animals that eat both plants and animals are called omnivores. The chain becomes a web, with many different animals feeding on others. Krill is food for seabirds, whales, and penguins, too. Krill is a part of many food webs.

7 Each living thing has its special place in the food web. This place is called their niche. Green plants and algae that make their own food using energy from the sun are called producers. Living things that feed on producers are called consumers. Consumers cannot make their own food. Decomposers, like fungi and bacteria, break down the remains of dead organisms and their wastes. For example, a dead tree rots. Bacteria and fungi break down the remains of the dead tree. Nutrients are returned to the soil. Then trees living nearby absorb the nutrients and use them to stay alive and grow. Matter that is no longer living is recycled by decomposers. Each animal has a special place in its community of plants and animals. A community is a place where plants and animals interact with the environment. Almost every living thing becomes food for another living thing. We are all linked in a web of energy that passes from one living thing to another.

| What Is Energy? By Patti Hutchison | |
1 Energy is defined as the ability to do work. Every living thing needs energy. Most of it comes from the sun. Plants are producers. They capture the sun's energy. They use it to grow and reproduce. Any energy that is not used by the plant is stored. Animals are consumers. They eat the plants to get energy for their own life processes. We need energy in order to be able to do anything.
Assignment= Please copy into your journal and complete this graphic organizer from the reading above
3 Solar energy flows through the food chain. The food chain is a diagram that shows how energy from the sun is used by producers. It also shows how this energy is transferred to consumers in an ecosystem.
Assignment= Please copy into your journal and complete this graphic organizer from the reading above
5 Energy sources are like natural resources. They can be renewable or nonrenewable. Solar energy is, of course, a renewable resource. The sun isn't likely to burn out for billions of years. It will keep sending solar energy our way.
6 Energy from plants is also a renewable energy source. Trees are cut for firewood to heat our homes. They can be replanted. If our forests are managed in this way, we will have wood to use as energy for years to come.
Assignment= Please copy into your journal and complete this graphic organizer from the 3 paragraphs of reading above
8 There is a scientific law that says that energy cannot be created or destroyed. However, it can change from one form to another. There are two basic types of energy. Energy is either potential or kinetic.
9 Potential energy is stored energy. Think of Niagara Falls. The water at the top of the falls has potential energy. Kinetic energy is the energy of motion. As the water falls over the cliff, the energy changes from potential to kinetic.
10 Gasoline, made from oil, is stored in a tank below the ground. At this point, it has potential energy. When it is burned in a car engine, it makes the car move. It now has kinetic energy.
11 Energy also comes in different "kinds." Some of these include chemical, electrical, mechanical, and nuclear energy. They light our homes. They power our machines and cars. All these different types of energy have one thing in common- they have the ability to do work.
