Parts of a Tree
The part of the tree that serves to protect the tree from invaders
What is bark?
The tallest layer of the forest
What is the emergent layer?
A forest that receives >200 cm of rainfall annually and has a high diversity of tree and animal species
What is a tropical forest?
The layer that is composed entirely of organic material, like decomposed plant and animal material
What is the O horizon?
The soil order that has permafrost in its subsoil and is nutrient poor
What is a gelisol?
The main function of leaves, the process of creating sugar from carbon dioxide, water, and sunlight
What is photosynthesis?
The layer of the forest that is best developed in a temperate forest as opposed to a tropical or boreal forest
What is the understory?
A forest that receives most of its precipitation in the form of snow and has low soil fertility
What is a boreal forest?
The layer that is composed of the parent material that has only slightly begun to be altered
What is the C horizon?
The soil order that is highly weathered and nutrient poor, often found in tropical and subtropical regions
What is an oxisol?
The part of the tree that affects understory development due to alteration in amount of light penetration
What is the canopy?
Where you would be most likely to find leaf litter or a dead animal
What is the forest floor?
A forest that receives moderate amounts of rainfall year round and has fertile soil
What is a temperate forest?
The three types of material found on the soil classification triangle
What are sand, silt, and clay?
The soil that is best for growing trees because of its strong horizon development
What is an alfisol?
The part of the tree that transports water and nutrients throughout the tree
What is xylem?
The 2 layers of the forest where you might find animals eating berries and seeds
What are the canopy and understory?
The type of forest where you'd be most likely to find a deciduous tree, like an oak or maple
What is a temperate forest?
The layer that is best for growing plants, as it has a high amount of organic material and is not leached
What is the A horizon (topsoil)?
Soils that are often found in grasslands and are high in organic material
What are mollisols?
The part of the tree that creates new cells to promote secondary growth, contributing to annual growth layers
What is the cambium?
The main reason why decomposition on the forest floor matters for forest health
What is nutrient cycling?
The type of forest where you'd be most likely to find a moose
What is a boreal forest?
The layer of soil that is almost entirely leached of minerals and organic material and is lightest in color
What is the E horizon?
The type of acidic soil common in the northern US that is sandy and low in nutrient content in the topsoil
What are spodosols?
