Observe an Organism:

The organism that I took a picture of from Blakeburn Lagoon park was a toad. I thought toad was the most interesting organism to research out of all creature that I took a picture of.

A toad interacts with biosphere as it eats insects such as flies, mosquitoes, moths, and dragonflies. On the other hand, a toad can be eaten by snakes and racoons. Toads normally resides near ponds along with frogs and catfish.

A toad interacts with biosphere by living in ponds. It hunts and make babies near the ponds where water is around.

As a toad eats many flying insects like flies and mosquitoes, it is interacting with atmosphere through its hunting.

Although, toad normally wander around near ponds, they are also able to exist near geosphere area like soil with grass or rocks.


From our study:

The temperature at Blakeburn Lagoon Park was moderate. It was about 7 Celsius degree at the coldest and about 20 Celsius degree at the peak.

It was cloudy, but not raining on the first trip. It was slightly raining during the second trip. During the last trip, it was sunny.

During the first trip at Blakeburn Lagoon Park, the satus of soil was normal and dry. The soil became very wet and muddy when it was raining during the second trip. I felt that shoes got sticky with some mud. During the last trip, the soil had become little dried, but still wet compared to the first trip.

When I started walking on the path, the starting spot had enough trees so that it was shady. It became sunny after 10 minutes of walking because there was less tree along the path. After awhile, it was shady again as bushes and plants along with trees were covering the path on the way back.

The sky was very clear and sunny at the time.

We started walking to Blakeburn Lagoon ark at around Park at around 11 AM, and arrived at 11:20 AM. We walked around the park for 20 minutes, then we returned back to Terry Fox Secondary at 12 PM.


Biological community:

There were distinct organisms that I have observed from Blakeburn Lagoon Park, which were a Red huckleberry, a goose, and a black worm.

A Red Huckleberry is a producer because it uses energy from the sun and nutrients from the soil to produce huckleberries. A goose is a consumer, which gets its energy by eating the huckleberries. A goose also depends on other producers like grass and berries. A black warm is a decomposer that recycles both producers and consumers after they die by breaking them down into nutrients that return to the soil.

The Red Huckleberry stores energy through photosynthesis. The goose and the black worm release energy through cellular respiration.

Food Chain

A Red Huckleberry (producer) >>> A goose (Consumer) >>> A black worm (Decomposer)


Food Chain:


Food Web:


If the population of consumer goose continues to decline, producers such as grass and trees will not have enough consumers to consume what they produce. Also, decomposers like mushrooms and worms will not have enough corpses to recycle. Then, the soil will not be able to receive enough nutrients because decomposers will not have enough consumers to decompose.


Symbiotic Relationships:

Parasitism is defined as a relationship between species, where one organism, the parasite, lives on or in another organism, the host, causing it some harm at the Blakecurn Lagoon Park, I have observed two different organisms in a relationship based on parasitism. I saw some fungi on trees at the park. The fungi were killing their host tree by sucking out nutrient because fungi benifits from tree while the tree is dying from it.



  • I can recycle and prevent using single-use items such as plastic and paper bags. This will keep the Earth sustained and keep the earth’s spheres to cycle. Our oceans won’t get dirty and we will be able to keep hydrosphere clean.
  • I won’t cut the trees in the forest. Cutting out trees produce carbon dioxide and it is unhealthy for Earth. If we keep producing carbon dioxide, temperature of the planet will rise and the climate change will become worse and worse. It will destroy the biosphere and atmosphere. Any flying organisms will get effected by rising temperature. Also, we are not going to get a lot of air to breathe because of carbon dioxide.
  • I can use less energy, something like unplugging appliances when I’m not using, or using cold water to wash clothes. This will be a good way to save money as well. If we use less energy, it’s good for Earth and saving.




First People’s Link: 

Douglas Fir was named by Scottish botanist, David Douglas in 1791. The size of the tree is usually 70-330 feet tall varies on the environment. The leaves are about 2-4 centimeters and it resemble the firs of the tree.

  • Douglas Fir helped Indigenous people for building houses. People still use Douglas Fir to build houses today. It is a strong material to use and it’s suitable for houses. It is hard to get destroyed since the material is durable. It can hold and protect inside of the house.
  • It is useful for building bridges. Whenever Indigenous people travel, they need bridges to go through the cliff. Douglas Fir will be perfect for bridges. I will be able to hold heavy weight, so it will be safe for people to go across it.




Once upon a time there was a small toad lying down on the bed. One day, the toad decided to move to the place named Blakeburn Lagoon city. Toad didn’t like the environment where he was living. It’s always dirty, neighbors were all predators, so it was really dangerous, and the toad was always afraid that he might get eaten by other predators. When it arrived at the Blakeburn Lagoon city, everything felt so comfortable and splendid. It felt like toad’s hometown. But, a disaster came to the city 15 days after toad moved in. A terrible group of species named ‘humans’ came to the city, and destroyed majority of the environment of the city. It happened all of a sudden. Lot of animals and plants died, and there were only few species left in the city, and toad was one of the survivors. Humans changed the name of the city to Blakeburn Lagoon Park, and made Lagoon their property. Survivors of the Lagoon destruction decided to stand up and take a revenge on humans. They started  war. The war continued for 20 years, and organisms from Lagoon have claimed the victory. Humans surrendered and they promised that they will rebuild Blakeburn Lagoon park. Now, which is 137 years later from the end of the war between humans and organisms from the Lagoon, all of the creatures who fought in war including toad are living in the park happily. Toad became the most  important organism to keep the Lagoon alive because it provides a very efficient trandfer of solar energy, and that helps the environment to sustain the nature. The solar energy keep humans to live. The solar energy that toad produce helps growing food and nutirents for humans. Toad’s body changed after the war. It changes the color of the skin depending on the environment.  If toad doesn’t exist at the park, Blakeburn Lagoon park wouldn’t exist today.

– The End.
