• What are the 7 processes that characterise all living organisms?

  There are seven processes that characterise all living organisms, including humans. Sensitivity: detecting and responding to changes within the body and its surroundings. Nutrition: obtaining food (nutrients) needed to supply energy to drive other the processes and provide building materials for the structures in the body.

• Do all living organisms have the ability to produce offspring?

  All living organisms have the ability to produce offspring. All living things are able to sense and respond to stimuli around them such as light, temperature, water, gravity and chemical substances. Learn these seven characteristics of living organisms.They form the basis of the study of Biology.

• Is reproduction essential for the survival of an individual organism?

  Reproduction is not essential for the survival of an individual organism. However, it is essential for the continuation of an organism’s species. A species is a group of similar-looking organisms that can interbreed and produce fertile offspring. If individuals in a species never reproduced, it would mean an end to that species’ existence on Earth.

• How do enzymes control the chemical reactions that sustain life?

  Enzymes control the chemical reactions that sustain life. Conditions inside the body must enable enzymes to catalyse the multitude of chemical reactions needed for life processes. Maintaining these conditions even when external conditions vary, sometimes quite considerably, is essential. This maintenance is called homeostasis.
