Write a couple paragraphs about how producers (plants) get their energy from the sun and animals that eat them take their energy and other animals eat them.

    First, plants receive and trap the sunlight using chlorophyll, the green substance that make up the color of the plants. Water (H2O) and carbon dioxide (CO2) from humans are also needed. The plants make their food (sugars) in this process called photosynthesis.

    Second, animals consume the plants and obtain the energy from the plants. Animals cannot survive without plants, for plants produce oxygen and energy. Animals are heterotrophs, while plants are autotrophs. After the animals obtains the energy, they breathe carbon dioxide out.

    Lastly, this process repeats over and over again. Plants are very important in animals' lives. This is why everyone wants to stop pollution and plant elimination. All in all, plants and animals rely on each other, and they cannot survive without each other.

Hope this helps!

the core of the sun is so hot and there is so much pressure, nuclear fusion takes place, hydrogen is changed to helium. nuclear fusion creates heat and photons. when the heat reaches the earth it warms the molecules of the atmosphere, and they warm other molecules and so on.
