Chapter 9 Living Things:
-
A species is a group of living things that are able to breed
-
An individual living thing is known as an organism. All organisms are made of units called cells
-
Ecology is the part of biology which studies how living things interact and depend on one another
-
The 7 life processes or charecteristics of a living things are
-
Growth
-
Movement
-
Nutrition
-
Respiration
-
Excretion
-
Response
-
Reproduction
-
A good way of remembering these 7 processes is through the acronym MEN GRRR or Mrs Gren
Explanation for the 7 life processes:
-
Growth: All living things can grow if they have enough nutrients to allow for that growth
-
Movement: All living things have the ability to move even plants move into the direction of the sun
-
Nutrition: All living things need nutrients to grow. Animals get nutrition from plants or other animals. Plants get nutrients from the air-Carbon Dioxide and soil-water
-
Respiration: During respiration animals extract energy from their food by taking in oxygen
-
Excretion: All living things must remove all waste that builds up through excretion
-
Response: All living things must be able to detect what is around them using their senses
-
Reproduction: All living things will eventually die. If they do not reproduce they will become extinct
-
Living things are sub-divided into plants and animals
-
Plants have the follwoing features: Leaves, branches, stem, roots, flowers, fruits etc
-
Animals are sub-divided into verebrates and inverebrates
-
Vertebrates have a backbone e.g. Snakes, dogs, humans etc
-
Invertebrates do not have a backbone e.g snails, jellyfish, starfish etc
-
A key can often be used to identify palnts and animals
