Science 6 Trees and Forests Flashcards

The non-living part of the environment that includes temperature, water (or lack thereof) day/night, etc.

The modification of alteration of an organism so that it adjusts to a new or altered environment.

The amount of trees which can be taken from the forest annually without significantly altering the balance of the ecosystem.

The visible outer covering of a tree which helps to protect the inside of the tree.

The many different species living in balance within a specific area or environment.

The living components of an environment.

The growing part of the tree where cells form actual wood.

The top branches and leaves of the trees in a forest.

CO2

A gas composed of carbon and oxygen that is produced when humans and living things exhale.

A meat eating organism.

The green substance found in leaves of plants that traps light energy used in photosynthesis.

The process of releasing energy from sugar and other organic molecules by combining it with O2 to produce CO2 and H2O as waste.

A method of harvesting trees where ALL standing trees are removed from a section of forest at one time regardless of whether they are usable or not.

Small, woody structures of coniferous trees which produce the seeds (a baby tree).

A tree which bears cones and has needles as leaves. Some examples are pine, spruce, fir or cedars. They are often referred to as evergreens.

An organism which feeds on other organisms in an ecosystem: herbivores, carnivores and omnivores are part of this group.

The top of a tree that forms the canopy.

Trees which lose their leaves every autumn or a broadleaf tree.

An organism which breaks down material and litter - the forest floor cleaners!

Putting seeds directly into the forest floor rather than planting seedlings.

An area of living and non-living components which form an environment.

A tree which does not lose its leaves and has needles instead of broadleaves.

A transfer of energy from the sun from one living thing to another.

The feeding relationships in an ecosystem. It shows how all organisms are connected in a specific ecosystem.

A group of trees. You had all better get this one CORRECT!!

The area around the base of trees, usually covered with leaves, moss and other plants.

The care and use of forests - it works to protect the forest.

Things that are made from trees.

The practice of managing, conserving and creating forests.

Rings that are present when you look at a tree cookie which are used to determine the age of the tree.

A preferred place where an animal or plant lives. or, in simpler terms, an animal's home.

The removal of trees for a variety of uses- logging.

The non-living wood, right in the middle of the trunk, making up most of a tree truck which gives the truck strength.

A plant eating organism.

The inner layer which serves to take food from the leaves to parts of the tree.

The state of being dependent upon each other for survival - being interconnected.

The trunk of a tree after its been felled (cut down).

The cutting and transporting of trees to the mill to make products. A very important industry in Alberta.

An organism which eats both plants and animals.

A specially designated area used for recreation.

The inner bark tissue that transports nutrients down to the roots and back up to the canopy.

The process by which a tree produces its own food (sugar) using sunlight.

Any organism which uses energy from the sun to produce its own food. These are generally ALL green.

The building of a new forest by replanting or reseeding - usually done after an area has been logged or damaged by fire.

The process of growing back what has been lost. Forests usually do this after a fire with the growth of new seedlings.

When trees "sweat" - trees release water back into the atmosphere.

The fluid part of a tree rich in sugar and starch which moves up and down the tree in the phloem tissue of the bark - maple syrup is one of these (yummmy!)

Code word for a young tree.

The softer outer layer of the wood in the truck between the cambium and heartwood - responsible for nutrient transportation. The live part of the trunk.

Code word for a baby tree.

A method of harvesting trees where certain trees are slelected for cutting and ONLY these trees are taken.

A low-growing perennial plant.

A standing tree which has begun to decay or a tree which has been felled but has caught itself on the way down. These are great for knocking over - but be careful of hornet nests inside the rotting truck.

A group of trees in a given area.

Little holes on the underside of leaves which allow the tree to "sweat".

A method of harvesting a forest in strip-like sections.

The loss of water through the stomata of the leaves.

A perennial plant that has a wood trunk and a self-supporting truck.

Microscopic tubes running throughout the trunk of a tree that transports water and minerals up from the roots.
