a fungus and algae working together. The fungus absorbs water and nutrients and the algae produces the food.
top of the forest formed by leaves and branches of the tallest trees. Birds (owl, orioles), and insects (aphids, tent catipillars) make homes here
level below the canopy. smaller trees and larger shrubs. provides sheltered space for birds and small mammals (squirrels, woodpeckers, insects).
plants convert sunlight, water, and carbon dioxide into oxygen and nutrients (sugars) for the plant to use
eats primary consumers.
so, snake - secondary consumer
mouse - primary consumer
eat secondary consumers.
so, hawk - teritary consumer
snake - secondary consumer
determining factors of cookies
1. differences in coloration and texture of new growth and old growth
2. if scars are present from fire or mechanical damage (very dark area)
3. if enough nutrients were present (ring growth)
4. if nutrients were not present (close together ring growth)
5. crowded conditions (close together)
the movement of food energy through the different levels of consumers
grass -> mouse(primary) -> snake(secondary) -> hawk(teritary)
all water in an ecosystem is recycled - 1. water goes into soil (percipitation),
2. taken up by trees, given off by trees (transipiration),
3. goes into the air as water vapour, condenses in the air and
4. falls as percipitation
evergreen trees -
DO NOT loose their leaves in the fall
cone bearing trees, needle leaves
In Alberta - lodgepole pine and jackpine
loose their leaves in the fall
often produce flowers and fruit
In Alberta - aspen and poplar
starts with the producer and ends with the decomposers.
how nutrients are cycled between the biotic and abiotic parts of the environment
level before the forest floor. ferns, wild flowers, stem plants, insects, butterflies, small mammals like mice, larger mammals like deer, skunks
fungus found attached to tree trunks. grow like steps or shelves and have growth rings like trees
the NON-living parts of the environment. soil, air, water, sunlight, temperature, wind, terrain
the inner part of the tree.
Function - carries food from the branches and leaves to the roots
organisms that lack roots, stems and leaves. cannot photosynthesize to make own food. examples - mildews, rusts, smuts, mushrooms, conks, molds
grow on the roots of trees. some help the tree by gathering nutrients and water. some harm trees
forests create a life by
supporting the environment (provide food, provides oxygen and exchanges carbon dioxide)
