My Zoo Research PDF(By: YeeTengChew) :

Decomposer, Scavengers, Omnivores, Herbivores, Carnivores, Producer, Primary Consumer -------- Tertiary/ Quandary Consumers.

1) The animals and organism in your animal's habitat.

2) Make your animal's food web poster.

3) Take a photo and post it into science wiki.

Food chain:

From the tiniest shrimp to the fish and a bigger fish. The bigger fish will be eaten be a bear. If the bear is hungry it will be dead and if the bear is dead it will be eaten be the scavengers.

African Lion:

What does the lion hunt for- Gazelle, Cheetah, Antelopes, Buffalo, Young elephant and Giraffe.

What does the lion need- Grass, Tree, Water, Sun, Foods.

What eats the lion- Scavengers include vultures, hyenas and flies.






List of the animals:

Zebra, Wildbeest, Warthog, Giraffes, Leopard, Rhinoceros, Hippopotamus, Cheeta, Buffalo and Elephant


In the Wild: grassy plains, savannas and semi deserts found in much of Africa south

of the Sahara Desert.

Grassy Plains

What do they belong to:

Vultures - Carnivore - Decomposer - Tertiary Consumer

Hyenas - Carnivore - Secondary Consumer

Elephants - Herbivore - Primary Consumer

Buffaloes - Herbivore - Primary Consumer

Rhinos - Herbivore - Primary Consumer

Antelopes - Herbivore - Primary Consumer

Zebras - Herbivore - Primary Consumer

Warthogs - Herbivore - Primary Consumer

Fungus- Decomposer

Bacteria- Decomposer

Dung flies- Decomposer

Grass - Producer

Trees - Producer


Role of Decomposer:

Decomposer is a type of organisms that break down dead. Like worms, molds, fungus, bacteria, millipedes, dung flies, jungle crow, vultures, hyenas and coyote. Their role is to eat animals or humans that is dead. Decomposer is everywhere around us in our body. The decomposer will be waiting for us to get old so that they can feed on us waiting for us to die. The decomposer is a very importance thing to the life cycle. If there is no decomposer there will be many dead bodies of animals.

Ecosystem - (Notes)

  • Habitat is a place where an organism lives and that provides the things the organism needs

  • Species is a group of similar organisms that can mate with one another to produce a baby elephant or tiger.

  • Population is the members of one species in a particular area

  • Community is the different populations that live together in an area

  • Ecosystem is a living and a non-living things that interact to form a particular area.

Definitions of Ecosystem:

An ecosystem is a relationship among the living resources, habitat, and residents of an area. It also have plants, trees, animals, fish, birds, microorganism, water, soil, and people.

What is habitat difference between habitat and ecosystem?

The difference between habitat and ecosystem is that, habitat is more related to the places where people or animals lives in.(Example: Grassy Plains and Ocean) And ecosystem is when two living thing and non-living thing combine together to form a environment of where animals lives in and same a people.

Descriptions of Ecosystem:

Ecosystems is a Ecological Systems, that are being made up of living and non-living things. It is where different populations in a habitat interacts with one another and with the physical environment around them. Every different environment has a different ecosystem. For example if I put penguins in a very hot place like dessert the penguins will end up dying in the dessert. If we put the penguins into the right place like Antarctic it will just be the thing for he penguin. It is because it is not too cold for them and not too hot.

African Lion's Habitat :

African lions is currently range in east, south and central of Africa, in grassy plains, savannas, open woodlands and scrub country. In the wild, lions eat wildebeests, zebras, buffalo, gazelles, wart hogs and other animals that may be in its area. The lions likes to come out at night so that he can hunt many animals without the others animals knowing it. The other reason it that hunting at the day is too hot for them to hunt the animals down. The size of the normal males lions and females lions is about three and half to four feet tall. The African lions are about two to eight feet long, with an additional two to three feet of tail. Adult male lions mostly to be weigh between 300 and 500 pounds, and female weigh is between 250 and 300 pounds.

My Food Web:

I think my poster turned out quite well, although I made four arrow the wrong way around where it says that the antelope eats the lion, and with the all animals that is on the poster, which is totally wrong. The reason I didn't wanted to make a new poster and that is because the date line is at the end of Tuesday and the day that I hand my poster in is at Tuesday, so I don't have time for making a new poster. I think that next time I should really think about what am I doing than do the real thing.

Non-Living Conditions (For Lions) :

Non Living Conditions


Grassy Plains

Search for water

Rains Fall

Hiding place

Hot Days

Place to block the heat ( The hottest day in Africa is 57.8°C (136°F) )

Cold Days

Thick fur and lots of fats ( The coldest day in Africa is - 24)

Objective 8:

Describe the feeding and symbiotic (parasitism, mutualism, etc) relationship that your animal has with organisms in it's habitat.

E.g. Leeches have parasitism relationship with....

Watch 'symbiosis' from brainpop.


Parasitism- Take for an example, when a plant grow on the tree and take the nutrients, it doesn't hurt the tree at all but the flowers will get the good things.

Mutualism- Is when both of them benefit.

Commensalism- Is between two organisms in which one benefits and the other derives neither benefit nor harm.

Lion's Symbiosis Relationship:

My male lion's symbiotic relationship with scavengers is mutualism and that is because they both benefit. Example: When the lions kill another animals the lions get to get and when the scavengers saw it they will also eat it so it is a mutualism.


Objective 9:

Describe the features of your animal that identify it as a species. If possible, describe variations between members of your species, for example polar and brown bear.

My lion features:
A lion's body temperature is from 38.05 to 39.16 degrees. There is magnificent roar to the lion and there is only four cats can roar: The lion, tiger, leopard, and jaguar. These four cats have been assigned to the genus Panthera because they can roar. Of these cats, the lion roars the most. It is beleived the roar serves to alert other lions of an individual's presence. It is said that a lion's roar can be heard 5 miles (8 km) away. A lion's eyes do not glow in the dark, but they have a special coating that will help them reflect even moonlight. The coating can increase the lion's visual acuity in very low light by ensuring. Their eyes are effective even by starlight. A white circle just below the eyes helps reflect light into the eyes to further improve night vision.

Objective 10:

Describe how variations are inherited or caused by environment.

What is variations:

Variation in a characteristic that is a result of genetic inheritance from the parents is called inherited variation.

Children usually look a little like their father, and a little like their mother, but they will not be identical to either of their parents. This is because they get half of their inherited features from each parent.

Here are some examples of inherited variation in humans:

  • eye color
  • hair color
  • skin color
  • lobed or lobeless ears.

Describe how variations are inherited or caused by environment:

I think that it is because of our genes. Our genes decide what do we do and what we behave. So that inherited us by our genes.
For an example-
  • A person might grow very pretty but his has a bad diet and she is short.
  • Plants may have the potential for strong growth, but if they do not receive sufficient mineral resources from the soil, they may hardly grow at all
