370 million years ago, trees left the ocean and took root on land, where they have flourished on the surface ever since. They photosynthesis, produce nutrients, store energy, affect countless creatures on the earth, it can be said that without trees, there is no life.
"Food Processing Plant"
The forest is like a laboratory, where energy from the sun is "processed" by the trees and converted into nutrients that can be used by other living organisms and stored in the trees.
Most plant photosynthetically synthesized sugars are first glucose, which is converted into starch, temporarily stored in chloroplasts, and then transported to various parts of the plant body; Plant photosynthesis can also synthesize proteins, lipids and other organic substances. It is these nutrients formed by plants through photosynthesis that provide the necessary energy for countless other living organisms, and the forest can be described as a veritable "food processing plant"!

Animals in the forest
In this forest north of Gaspé, Canada, there are many animals living there. North American red squirrel, yellow-bellied juice-sucking woodpecker, black-hat, American black bear, red-breasted, cedar peacebird, red-throated northern hummingbird, etc. They all have their own unique features, and many small animals have subtle connections between them.
Yellow-bellied sap-sucking woodpeckers peck out a circle of small holes in the trunk, and insects attracted by the sap of the trees become their "after-dinner snacks". At the same time, their habit also provides access to food for many animals around them, such as the red-throated northern hummingbird, but it can also cause harm to some trees.

There are also "engineers" beavers, who are highly skilled and able to transform the environment of their habitat. This cute little animal comes out day and night, toiling hard, building nests and dams in the river channel, creating a safe zone for itself that can "eat and drink without worry".

Pest crisis
The forest is always full of vigorous vitality, but in fact, the forest will also encounter crises. This forest north of Gaspé is infested with spruce-colored curl moths. This creature can harm the leaves of tree species such as spruce and fir, and they will spit silk around the leaves and branches, and when severely affected, spruce and fir will be entangled with millions of silk threads. This pest is cyclical and causes many trees to wither and die.

But on the other hand, the flood of spruce-colored curly moth caterpillars provide food for many birds. At the same time, this natural disturbance is also an inseparable part of the forest ecosystem, after the old generation of trees withered, for the new generation of trees to make room and resources for growth, the so-called "diseased trees in front of the head of the spring", it is this new and old alternation, the forest can maintain a long-term vigorous vitality.
