Bio

• There are seven characteristics of living things.
• What is an organisms?•Carries out living processes.
• •There are about two million different types of organisms.
• M for Movement

  R for Respiration

  S for Sensitivity

  G for growth

  R for Reproduction

  E for Excretion

  N for Nutrition
• Movement •Change of position needed to respond to the surrounding
• •Animals move their whole body from place to place
• •Plants can only move parts of their body
• Respiration •Release of energy from food OR•Stored chemicals in cell for immediate use by the organisms
• Sensitivity •Respond to different stimuli
• •Plant will grow in the direction light is coming from
• •Animals may move in response to seeing something coming towards them
• Growth Individuals start off small and grow until adulthood
• •Animals often have a maximum size
• Plants continue to get bigger over all of their life
• Reproduction Creates new individuals
• •Replace those that have died.•Ensure the survival of the species.
• excretion •Removal of waste product by chemical reactions in cell of the individual.•Includes gases (carbondioxide),special compounds (urea) and water.
• •Plants excrete toxins into their leaves .•Then drop the leaves in autumn.
• Nutrition (feeding)•The organisms must take in energy to keep it alive.
• •Plants take in simple compounds and light to make their own chemicals.
• •Animals eat plants or other animals to get complex compounds from them.
• Types of ecosystem

  Terrestrial ecosystem 

  Aquatic Ecosystem
• Terrestrial ecosystem

  •Rain forest•Taiga•Tundra•Deserts•Savanna•GrasslandsForests
• Aquatic ecosystem

  •Fresh water•Brackish water•Marine
• •The surface of the Earth where living things can survive is called the Biosphere
• The place where each organism can live is called its habitat
• •The combination of the community of organisms  and the non living  (physical) environment  is called the ecosystem.
• Ecosystems are often grouped  together on a global scale to give biomes
• •Different  species  (types of organisms) will each be adapted to that particular habitat and form an interacting group- a community of organisms.
• •The organisms interact with the non –living environment.
• To us the earth is a very special place.
• •Life may have started about 3500 million years ago and organisms are now able to live in most areas of the sea ,land or air.
• •Very few areas are entirely free of life.
• •Organisms live in specific places in the biosphere.
• •This is a local environment which usually describes the main type of plant or the structure of the environment
• ecosystem

    The basic unit from which living things are made.
