Coastal Redwood trees (Sequoia sempervirens) are the tallest trees in the world - reaching up to 380 feet tall (that is as tall as a 38 story-building). They grow along the northern California coast up to the southern Oregon border, where they rely on ocean fog during the summer to supply their massive canopies with moisture. The canopy of a tree is the above-ground area that contains the branches and sometimes it's own unique biological community. Coast Redwood trees have the most biologically complex and diverse canopy communities of any organism in a temperate climate.
Redwood Tree Canopies
Food Webs occur wherever here is life - even 360 feet up in trees. Start at 6:45 and stop at 9:20
Food Web Activity #14 Life in a Redwood Tree Canopy
Start by drawing a coast redwood tree canopy, then add your producers. Remember, all ecosystems start with producers! Here is an example of what I came up with this morning on my iPad. Now I just need to add the consumers...
Mr. Abbott's Redwood Food Web
Student Teacher (8th Grade Physical Science) Mr. Abbott - drew his own Redwood Food Web on his iPad. This is a great example of where to start. Be sure to LABEL the various levels (organisms) on your drawing as either producer or consumer - and then label the consumers as either herbivore, omnivore, carnivore, or scavenger / decomposer.
Topics Covered Food Webs Flow of Energy in Ecosystems
Vocabulary (students are expected to know) Wow! This is a lot!!! I will make a study sheet. You already have most of this down though, so that is...well, awesome.
Students should be able to apply vocabulary terms from lesson plans 1-3 to real-life situations in the field.
Ecology: the scientific study of the interactions between organisms and their environment.
Biotic: all the living things in the environment.
Abiotic: all the physical factors in the environment that affect living organisms - Temperature, Light, Water, Nutrients.
Organism: the individual living unit - you, me, a bird, a tree, a single cell organism.
Population: a group of individuals of the same species that live together in the same area.
Community: ALL of the populations of different species that live and interact in one area.
Ecosystem: a community of organisms and its abiotic environment.
Biosphere: the part of our planet with living organisms.
Producer: organisms that use sunlight to directly make food.
Consumer: organisms that eat producers or other organisms for energy.
Herbivore: a consumer that eats plants for energy.
Carnivore: a consumer that eats animals and other consumers for energy.
Omnivore: a consumer that eats both producers and consumers for energy.
Scavenger: animals that feed on the bodies of dead animals for energy.
Decomposer: organisms that get energy by breaking down the remains of dead organisms.
Energy: the ability to do work.
Food Chain: shows how energy in food molecules flows from one organism to the next.
Food Web: shows the many energy pathways possible.
Energy Pyramid: shows the loss of energy at each level of the food chain.
