Answer:
Energy in an ecosystem is mainly made by the producers of an ecosystem. The net primary productivity in an ecosystem depends on many factors. Some of them are:
- Amount of sunlight: The amount of sunlight that the plants and trees might be has basic influence on the primary productivity. Plants and trees receiving enough sun light will be able to make more food for organisms living in that area as compared to the producers which do not receive enough sun light.
- Soil texture: The soil texture and the availability of nutrients heavily influence the primary productivity of an ecosystem. An area having a soil texture with not enough nutrients will not be able to grow more plants. As a result, the productivity would decrease.
A scientific model is a claim or a theory that helps explain how a phenomenon works or how it undergoes process. This models provides scientists an understanding of the object or a situation undergoes change and generate certain outcomes or effects.
During photosynthesis, plants take in light energy from the Sun, carbon dioxide from the air, and water through their roots. Oxygen is a product of photosynthesis.
The tree would contain carbon.
