The kingdom name is Eubacteria which is also its scientific name. They are also called true bacteria or monera.
There are different sorts of bacteria and they each get their food in a different way. Some of them are producers. Producers change the energy they get from sunlight into energy which the cells can use. Other bacteria are decomposers. Decomposers get their energy by breaking down materials in dead or rotting organisms. They can also be parasites; these bacteria live on or in other organisms and get their food from them.
Eubacteria cells are prokaryotic because they don’t have a nucleus or organelles.
Eubacteria cells are unicellular organisms because they only consist of one cell.
1) An example of eubacteria is the blue green algae with the scientific name cyanobacteria.
1) Blue green algae already exist for more than 3 billion years. They are the biggest group of photosynthetic bacteria. They live in shallow waters all over the world.
2) They produce energy (oxygen) through photosynthesis, and they contain chlorophyll. Blue green algae are important for the environment because they give the animals the oxygen they need to stay alive.
2) Another example of eubacteria is Salmonella with its scientific name Salmonella typhi.
1) Salmonella bacteria give health problems like typhoid and food poisoning. Food poisoning will make you very ill and can even kill you. These bacteria can be found in raw meat and eggs. That’s why it is important to cook your food.
2) These Salmonella bacteria are rod shaped and. Rod shaped bacteria are called bacilli.
The Salmonella bacteria belong to the Eubacteria kingdom because they are unicellular, prokaryotic cells which are very small. They are rod-shaped, have a cell wall and contain DNA but have no nucleus and other organelles. They are classified in the Eubacteria kingdom because they are unicellular, prokaryotic organisms. They are consumers (decomposers).

Species of Fungi
One organism in the fungi kingdom is yeast. Its scientific name is Ascomycota. Yeast is a single celled fungi that grows in wet places. They’re in the fungi kingdom because they reproduce with spores and use hyphae to get food.
1. Yeast can grow on human skin, plant sap, animal tissue, and even shower curtains!
2. Yeast helps bread rise by breaking down sugar.
3. Yeast can cause disease if it grows too fast.
1. Molds can be used for treating disease. Penicillin is a medicine from the Penicillium fungus. It is used to fight pneumonia.
2. The hat thrower mold grows in animal droppings. It has a cap that holds spores in. When it gets enough water, the cap shoots off and sends spores in to the air. The spore cap can be shot up to two meters!
3. Trichoderma mold’s digestive chemicals are used to blue wash jeans.

The kingdom name is Animal. Its scientific name is Animalia also called Metazoa.
Animals are consumers. Consumers are living things which get their energy from other living things. Without eating food (other organisms), animals will not survive. This is called heterotroph. Animals get their food in different ways: Herbivores- eat plants, Carnivores- eat other animals and Omnivores- eat both.
Animal cells are eukaryotic cells because they have a Nucleus and they have organelles. They are animal cells because they have no cell wall and no chloroplast. Animals are multicellular organisms.
1) An example of an animal is a Human with the scientific name of Homo sapiens.
1) Humans are the most complex and developed organisms in the Animal Kingdom, they can read, use tools, talk, write etc.
2) Humans are animals which stand on 2 legs, don’t have much body hair. Males are generally larger than females.
Humans are part of the Animalia Kingdom because they are multicellular organisms. They are consumers ( heterotroph). They have eukaryotic cells.
2) Another example of an animal is a sea bass
The scientific name of the European Sea Bass is Dicentrarchus Labrax.
1) To get oxygen the sea bass uses gills. When water flows over the gills it picks up dissolved oxygen.
2) The European Sea Bass is a fish which is about 1 meter long. It can weigh up to 10 kilograms.
It belongs to the kingdom Animalia because there are multicellular organisms which are consumers (heterotroph). They have eukaryotic cells.

1) Tulipa gesneriana or Tulip is a very common flower. In this picture it is spring because the flowers have not blossomed yet. They grow up because they need sunlight to create sugar, which is what they produce. They are in the Plantae kingdom because they produce these sugars and are stationary.
2) Acer Ginnala or Amur Maple is a common tree, especially in the US. The tree grows up to reach towards the sunlight, to get more of it. The sugars it will get from sunlight is its’ meal. Also its’ roots go deep underground to get water. It is in this kingdom because it is stationary and it produces sugars.
