What is the canopy of a forest?
The forest canopy is a structurally complex and ecologically important subsystem of the forest. It is defined as “the aggregate of all crowns in a stand of vegetation, which is the combination of all foliage, twigs, fine branches, epiphytes as well as the interstices (air) in a forest” (Parker, 1995).
What is in forest floor?
The forest floor can consist of short vegetation (like grasses, mosses, bushes, and creeping vegetation), litter as described by Hoover and Lunt (1952) as the litter and fermentation (L and F) layer (i.e., leaves, twigs, and small branches), or bare soil.

Where is the canopy of a tree?
The canopy is the dense ceiling of closely spaced trees and their branches, while the understory is the term for more widely spaced, smaller tree species and juvenile individuals that form a broken layer below the canopy.
What is canopy and its types?
Canopy is the outermost layer of the leaves formed by an individual tree or by the group of trees. It restricts the sunlight and rains from getting into the layers which are below the canopy. The leaves here are broader and so on raining water drips from the canopy to the forest floor.
What is on the forest floor of a rainforest?
The forest floor is all of the leaf litter – everything that falls to the floor – all the leaves and bark and perhaps dead animals and anything that will decompose makes a really rich soil for lots of invertebrates to live in. Kind bacteria which live in the soil and funguses that help all the plants to grow.

What animals live in the Amazon forest floor?
The last layer of the rainforest is the forest floor layer. This layer is dark, humid, and hot. Only 5% of the sunlight makes it to the forest floor. Anteaters, jaguars, and scorpions are some of the animals that live in the forest floor layer.
What is the forest floor?
The forest floor is where recycling occurs, fungi, insects, bacteria, and earthworms are among the many organisms that break down waste materials and ready them for reuse and recycling throughout the forest system. Herb layer: The herb layer of the forest is dominated by herbaceous (or soft-stemmed) plants such as grasses, ferns, wildflowers, ...
What are the layers of a forest?
Mature forests often have several distinct vertical layers. These include: 1 Forest floor layer: The forest floor is often blanketed with decaying leaves, twigs, fallen trees, animal scat, moss, and other detritus. The forest floor is where recycling occurs, fungi, insects, bacteria, and earthworms are among the many organisms that break down waste materials and ready them for reuse and recycling throughout the forest system. 2 Herb layer: The herb layer of the forest is dominated by herbaceous (or soft-stemmed) plants such as grasses, ferns, wildflowers, and other ground covers. Vegetation in the herb layer often gets little light and in forests with thick canopies, shade tolerant species are predominant in the herb layer. 3 Shrub layer: The shrub layer is characterized by woody vegetation that grows relatively close to the ground. Bushes and brambles grow where enough light passes through the canopy to support shrub growth. 4 Understory layer: The understory of a forest consists of immature trees and small trees that are shorter than the main canopy level of the tree. Understory trees provide shelter for a wide range of animals. When gaps form in the canopy, often times understory trees take advantage of the opening and grow to fill in the canopy. 5 Canopy layer: The canopy is the layer where the crowns of most of the forest's trees meet and form a thick layer. 6 Emergent layer: Emergents are trees whose crowns emerge above the rest of the canopy.

Why do different species use different layers of the forest?
Different species use the various structural aspects of the forest in their own unique ways. Species might occupy overlapping layers within a forest but their use of those layers might occur at different times of the day so that they do not compete with one another.
What is the composition of a forest?
Species Composition. The species composition of a forest is often unique to that forest, with some forests consisting of many hundreds of species of trees while others consist of just a handful of species. Forests are constantly changing and progress through a series of successional stages during which species composition changes within the forest.
Where do forests occur?
Forests are habitats in which the trees are the dominant form of vegetation. They occur in many regions and climates around the globe— the tropical rainforests of the Amazon basin, the temperate forests of eastern North America, and the boreal forests of northern Europe are just a few examples.
What is the understory of a forest?
Understory layer: The understory of a forest consists of immature trees and small trees that are shorter than the main canopy level of the tree. Understory trees provide shelter for a wide range of animals. When gaps form in the canopy, often times understory trees take advantage of the opening and grow to fill in the canopy.
What is the difference between a forest and a wood?
The difference between woods and forests comes down to canopy cover and tree density. While forests are known for thicker canopy cover (the amount of land covered by the tops of trees), woods usually have a more open canopy and sparser tree density, keeping the soil drier and unshaded. Although both refer to distinct ecosystems covered in trees ...
