Final answer:
Organisms need nutrients, energy, and excretion mechanisms to grow, reproduce, and maintain internal balance, essential for survival and propagation of the species.
Step-by-step explanation:
Organisms need nutrients for growth, reproduction, and maintaining organization. Nutrients are essential for providing energy and materials for the organism's metabolic processes. For example, carbon, hydrogen, and oxygen are important nutrients required for energy production, while other nutrients like nitrogen and phosphorus are essential for building proteins, DNA, and other cellular components.
Reading is not primarily a requirement for organisms, as it is a skill specifically developed by humans for communication and acquiring knowledge.
Reproductive processes are essential for the survival and continuation of species. Organisms have evolved different reproductive strategies, such as sexual reproduction or asexual reproduction, to produce offspring. These offspring inherit traits from their parents, which contributes to genetic variation within populations.
Excretion is necessary for removing waste products from the organism's body. Waste products, such as carbon dioxide, urea, and excess salts, are by-products of metabolic processes and can be harmful if accumulated. Organisms have specialized organs, like kidneys and lungs, to excrete and eliminate these waste products.
