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.
The most prominent organelle that contains genetic material and is visible in most eukaryotic cells is the Nucleus.
<h3>What is Nucleus?</h3>
- The nucleus is a double membraned organelle found in all eukaryotic cells.
- It is the largest organelle, which functions as the control center of cellular activities and is the storehouse of the cell's DNA.
- The nucleus is dark, round, and surrounded by a nuclear membrane.
- Within the nucleus, there are tiny spherical bodies called the nucleolus. It also carries an essential structure called chromosomes.
- So the nucleus is the organelle that is visible and present in all eukaryotic cells.
