Five characteristics of living things, which are comprised of one or more cells, include the ability to grow, adapt and reproduce, along with responsiveness to stimuli and metabolic processes necessary for survival. The term "living things" encompasses animals, plants and simple organisms, such as amoeba, fungi, viruses and bacteria. Scientifically, living things are categorized into animal and plant kingdoms, depending on their similarities.Know More
The cell is the basic unit of living things, and its chemical processes and components have fundamental similarities in all living organisms. Cells contain genes, which determine the unique characteristics of living things. In addition, living things require energy to survive. Plants use the sun to make their food, but animals depend on food from the environment. Living things develop or grow through organized changes in shape and body functions.
Growth also involves the process of repairing damaged cells and tissues. Responsiveness to the environment allows living things to adapt to change and survive. The ability to move is limited in some living things, such as plants. Most living things also work and depend on other life forms for survival. For example most animals depend on other animals and plants for nutrients. They also compete for resources, such as food, moisture, sunlight and space. When living things die, bacteria and fungi act upon their cells and tissues, causing decay and release of nutrients to the soil for plants to absorb and utilize.Learn more about Biology
A nonliving thing is a body or object that is inanimate or dead. It is anything that lacks or stops displaying the characteristics of life. One of the most significant characteristics and differences of a nonliving to a living thing is its lack of protoplasm, which is the living substance of cells. Without protoplasm, nonliving things are not capable of reproduction, growth, movement, respiration and metabolism.Full Answer >
All living things require a source of energy, nutrients, water, space to grow and reproduce, and a relatively stable environment that allows homeostasis. Many organisms also require oxygen, but this is not a universal requirement, and oxygen is actually deadly to certain organisms. Indeed, beyond these basic categories of needs, the requirements of organisms vary vastly from species to species.Full Answer >
Water covers about 75 percent of the planet and since plants are absent from major water sources like oceans; the survival of virtually all marine life solely relies on algae. Algae form food from water and carbon dioxide via photosynthesis, using the sun´s light and converting it into energy.Full Answer >
According to the Merriam-Webster dictionary, "metabolism" is defined as the chemical process a plant or an animal uses to create energy needed for survival. Metabolism is responsible for everything from digestion to breathing and muscle movement.Full Answer >
