Living things reproduce, grow, adapt to the environment, respond to stimuli and metabolize. They also undergo homeostasis, collect and convert nutrients, and use energy. Living things are organized into one or more cells. The five groups of living things are the animal, plant, monera, protista and fungi kingdoms.Continue Reading
Living things reproduce either sexually or asexually, resulting in new organisms. Homeostasis allows living things to maintain a steady state of their internal environments, such as temperature and electrolyte concentration. The cell is the fundamental unit of life, and cells are organized into tissues, organs and organ systems. The cells of living things differ in function and structure, but they all have genetic material, which determines their characteristics. Algae and plants utilize energy from the sun to make their own food during photosynthesis. Other living things obtain energy from food substances during metabolism.
Living things store surplus energy in form of chemical compounds, such as fats and carbohydrates for later use. Life processes, such as digestion, absorption, excretion and assimilation, are common to most living things. The growth of living things occurs in an organized pattern and involves changes in size and shape and maturity of body parts to perform adult functions. The development of simple living things, such as amoeba and bacteria, is relatively limited. Complex organisms, such as animals, have a complicated process of development. Living things are able to move, but some, such as plants, have a limited power of movement.Learn more about Biology
Living things like animals and plants can interact with the non-living environment, including the soil, climate and water, to cause effects on each other that can be positive, negative or neutral. For example, animals benefit from a non-living environment with plenty of water and air because these are essential for survival. If a living organism cannot adapt to its non-living surroundings (such as a lack of sunlight or too hot or cold temperature) or cannot get what it needs from these surroundings (such as water), then the living organism will have problems surviving and will thus be negatively affected.Full Answer >
Biotic factors are living things, such as plants and animals, that affect or influence their ecosystems and the lives of other living things in the environment. The biotic factors in an organism's environment include both the prey that the organism consumes and the predators that consume the organism.Full Answer >
Some of the characteristics of living things are the ability to reproduce, active response and adaptation to the surrounding environment, cell composition and growth and development. Life forms have to exhibit all the characteristics to be considered a life form; spontaneous generation from chemical reactions is not an example of a life form.Full Answer >
Living things are biological structures that respond to changes in the environment or within their own entities. This includes animals, plants, fungi and the single-celled organisms known as bacteria. Living things have complex biochemical organizations that allow them to process substances and utilize energy in order to respond to changes around them.Full Answer >
