For example, you might ask a Friend about photosynthesis; How does it work? Or, how does the food we eat go from your body to mine? That is something you could find on a Worksheet.
An organism can exist only in an environment that is rich in oxygen and food, like our atmosphere, and it can not exist without this rich oxygen and food, and other life forms in the ecosystem. To get those organisms, the oxygen is supplied by the Sun, and it is also by natural processes like rain. Also, for the food we eat we have to get it from plants. Plants produce the food, and animals feed on that food.
The way photosynthesis works is that photosynthesis makes use of carbon dioxide. Without the carbon dioxide, photosynthesis cannot work, as without that, it cannot make the molecules it needs to live. So, photosynthesis is used to supply the carbon dioxide to other creatures that can use it.
The organisms in the ecosystem take up carbon dioxide and convert it into a form that they can use, and some of it will escape back into the atmosphere. The plants are the ones that absorb this carbon dioxide and get it back to the atmosphere and to us. The animals that eat those plants take it out of the food that is consumed and put it into their own bodies, usually to be excreted out.
To find out how many organisms there are in an ecosystem, count all the different plants in it. If there are more animals than there are plants, then the ecosystem has more plants than animals. Then you should count the number of animals, because you would not want to live in an ecosystem where there are more animals than plants.
If you are aware of the role of photosynthesis in carbon cycling then you can expect to find on a Worksheet. You might find in theWorksheet some basic figures, but you should be able to work out how it works.
The people who live in the ecosystem know a lot about the role of photosynthesis in carbon cycling. They know how photosynthesis in the ecosystem works, what the ecology is, where the plants are, where the animals are, where the food is, and the role of these things in the ecosystem.
The people who live in the ecosystem are scientists, so they have much knowledge of how the carbon cycle in the ecosystem works. So, if you would like to learn more about the carbon cycle in the environment, then you might find the carbon cycling on a Worksheet will give you a good idea of how things work in this part of the world.
