Answer:
The sun
Explanation:
The is because the sun is the souce of energy
Photosynthesis
Photosynthesis is the production of ATP through the conversion of energy from sunlight using chlorophyll.
Chlorophyl is found in plants, and plants use sunlight to make energy.
That energy is in the form of ATP.
1.)Coral reefs are busy underwater ecosystems. Some people call them the “rainforests of the sea.” The corals look like rocks but actually are animals. They have hard calcium carbonate skeletons like clams. They form a base for lots of other organisms to live. You’ll find crabs, sea stars, worms, clams, sponges, jellies, sea turtles, and lots of fish. Coral reefs are complicated and very fragile. They are easily affected by pollution.
2.) Tropical rainforests are near the equator where it’s almost always warm and wet. These are the key ingredients for making lots of lush plants and trees. Half of the world’s plants and animals live in tropical rainforests. It’s a very busy ecosystem with many kinds of plants, animals, fungi, and microscopic organisms. Many of them live here and nowhere else.
3.) In the world’s many deserts, there is very little rain. The land is very, very dry. Here, living things have creative ways of finding and saving water. Cactuses are very good at storing water. They can live without rain for months. The kangaroo mouse lives in the Nevada desert. It rarely drinks water. It can get its water from the food it eats.
Solid:
•Has a definite shape and volume.
•It has the lowest energy.
•These are hard to compress.
Liquid:
•Has a definite volume, but take the shape of the container.
•It has medium energy.
•You can compress them a little difficulty.
Gas:
•Has no definite shape or volume.
•They have the highest energy.
•These are easily compressible.
