All elements of a ecosystem work together, the sun provides sun light which plants use photosynthesis for food. Small animals eat the producers aka the plants. Then other animals eat those. And so on if a plant wasn't alive then the whole ecosystem will fail.
Cells maintain homeostasis by consistently developing energy. Without energy, cells would fall into disorganized, unorderly processes and eventually cell death would occur. Cells also maintain homeostasis through diffusion and the plasma membrane, but regulating substances that enter and leave the cell.
The human body maintains homeostasis through body temperature, hydration, and food intake
It is not easily recognizable
Topsoil (horizon A):Very rich in humus(dead organic matter like plants) and minerals.
Subsoil (horizon B):less rich in humus and minerals
Weathered Rock (horizon C):Little or no plant life due to it being all rock
Hope this helps :)
Macromolecules in the mammals are of three different types, namely the carbohydrates, proteins, and the nucleic acids. Among these macromolecules, the nucleic acids are capable of self-replication. These encode the genetic information of the organism, and plays a vital role in carrying out an array of different functions of the body. One example of such nucleic acid is the RNA, or the Ribonucleic Acid.
