Living and non living things
Everything on earth can be classified as either living or non living things. Living things include plant and animals which have life while non living things are things that do not have life exaole of living things include man, rabbit, elephant, monkey, sheep, dog, grass, mango tree while non living things include air, water, stone, table, house, book, pen, chair etc Characteristics of non living things Movement Nutrition Respiration Excretion Irritability or sensitivity Growth Reproduction Asexual reproduction Sexual reproduction Adaptation Life span/death Competition Difference between plant and animals ; Plant and animals are living things but they till exist differences between them the difference between plant and animal are shown below PLANT: Most green plant carry out photosynthesis but non green plant cannot while ANIMALS : animals cannot carry out photosynthesis they depend on olabt for food PLANT: Growth is mainly restricted to growing regions or apical meristem while. ANIMALS: growth takes place in all party of the body or intercalary PLANT: plant are not active and have no organ of movement while ANIMALS: animals are active and have organ of movement PLANT: Plant have slow response to external stimuli while ANIMALS: Animals have fast response to external stimuli PLANTS: They possess no special excretory system while ANIMALS: They possess well-developed excretory system.

Movement: movement is defined as the ability of an organism to move its own whole body or part of its body from one place to another. Living things move in order to look for food for reproduction and to run away from danger or respond to the environment. Generally, most animals can move themselves from one place to another, while plants can only move part of their bodies in response to eternal stimuli
Nutrition : nutrition is defined as the ability of living organism to feed the reason for feeding is to enable living things live and carry out life processes like growth, respiration and reproduction. While all green plants can manufacture their own food through the process of photosynthesis.
Respiration: respiration is defined as the exchanged of gases between organisms and their environment. Living organisms take in oxygen and breath out carbon dioxide. The purpose of respiration is to burn down or oxidise food substance in order to release energy which is used for all life processes.
Excretion : Excretion is defined as the removal of metabolic waste products from the body the purpose of excretion is to remove waste products of metabolism e. g water and carbon dioxide, which are poisonous or toxic to the body. The process of getting rid of these poisonous metabolic waste products from the body is called excretion.
Reproduction : reproduction is defined as the ability of living organism to give birth to young ones or offspring. The purpose of reproduction is to ensure continuity of life that is its enables life to be passed on from one generation to the next.
Competition: This is the ability of living things to stuggle for all the necessities of life in order to survive intgeir various environment. Living things compete for food, light space, water, mates etc in order to survive and be in continuous existence
Adaptation :adaptation is a way of living organism gets used to their various environment in such a manner that they would be comfortable. This is done in order to survive.
