Characteristics of living organisms
What are the seven characteristics of living organisms?
Movement - Respiration - Sensitivity - Growth - Respiration - Excretion - Nutrition
A group of invertebrates characterized by having hard outer skeleton and jointed legs
Arthropods
They live in water, scales are covering their bodies and breath through gills.
Fish
Plants that have no true roots, stems or leaves.
Liverworts and mosses
Animals with backbones
Vertebrates
What is the characteristic of living organisms when they respond to their surroundings?
Sensitivity
These animals have spiny skins
Echinoderms

Amphibians

Worms
They all have feathers and beaks, they have two legs and two wings even if they can't fly.
Birds
They produce flowers and seeds which are contained in their fruits.

Scientists use similarities and differences to put things into groups. What is this called?
Classification
Living organisms use this process to make energy from food.
Respiration
They have muscular bodies and no legs but they may have tentacles. Some live on land such as snails others live in water such as octopuses
Molluscs
