New words from animal kingdom reading



New words from animal kingdom reading

Monday’s reading
Organism - a living thing Vertebrate - has a spine Invertebrate - has no spine Taxonomy - a way to group things
Diverse - a big range Amphibians - organisms that live in water and on land Heterotrophic - means they must find and eat food Autotrophic - an organism that can make its own food Primates (apes, monkeys)
Rodents (rats, squirrels) Cetaceans (dolphins, whales) Marsupials (kangaroos, koalas) Monotremes (egg laying mammals like the platypus) Autotrophic - make their own food by photosynthesis Photosynthesis - how plants make their own food Vascular - uses roots to absorb water Nonvascular - uses the whole plant to absorb water Decompose, decomposition - to break down
Non-flowering - no flowers Thermophiles - (root word is thermo which is about temperature) Big ideas from the reading All living things are called organisms. They are organised into 6 groups called kingdoms. Each group has certain characteristics that each organism must have.
Animals Can move on their own Are heterotrophic (can’t make their own food) Must eat to survive
Vertebrates and invertebrates Plants They are Autotrophic (they make their own food) Some are vascular and nonvascular. If a plant has seeds or fruit, it is a flowering plant. Eubacteria Are made up of just one cell. They are everywhere. Some bacteria are good and some are bad. Bacteria called decomposers break down dead plants and bacteria. Archaebacteria Can survive where no other organism can live.Thermophiles, methanogens and halophiles Fungi Say it fun guy Mushrooms are a fungi They are heterotrophic (can’a make their own food) Use enzymes to break down food Protista
Are related to either plants, animals or fungi (one of them, not related to all of them at the same time)

Fossils

Fossils are dead animals or plants. They are usually skeletons found embedded in rock. Sometimes fossils are footprints or poo. Small animals or insects get stuck in tree sap which hardens and traps them forever. Large animals can get trapped in ice, or their carcass gets trapped in larger of rock. Over thousands of years, pressure builds up and the skeleton is dissolved by water under the ground. Next the mould left is filled with minerals that form rock. This rock shape is fossil an exact replica of the dinosaur. This process takes 10,000 years. Palaeontologists find fossils when the top layer of dirt or rock washes away.

Palaeontologists - People who study dinosaurs.

Inheritance - something you get from your ancestors.

Adaptation - Change.

Evolution - Change over time.

Trait - Something that belongs to a person

Fossilised
