ECOSYSTEMS Again!

Explore ecosystems! Learn about biotic/abiotic factors, food chains, and energy transfer.

Ecosystems and biomes Click video tile to bring up Khan Academy video. You may need to pause and "rewind" video as needed. You may also use the next link that has notes about the video. Ecosystems Reinforced Fill-in the blank by typing in the best correct answer. Spelling will count. An ecosystem is made up of all the living (biotic) and non-living (abiotic) factors in an area. Click on the descriptors to classify each as biotic or abiotic factors. Biotic insects animals plants Abiotic sunlight water dirt Fill-in the blank by typing in the best correct answer. Spelling will count. There are two main categories of ecosystems are terrestrial ( land ) and aquatic (water). Click on the term and then the best given definition for the term to connect the matching items. population all of the same species in one area community all of the populations in an area biome large geographical area with similar rainfall and temperatures biosphere the area in which life can exist ecosystem all the living and non-living things in an area Matter is Recycled in Ecosystems Do you remember the links in a simple food chain? Copy and paste the following terms into the correct blank:Second Order Consumer Producer First Order Consumer Decomposer Second Order Consumer Decomposers Producer First Order Consumer Energy is NOT Recycled While matter is recycled over and over, the energy in ecosystems begins when autotrophs trap energy from the sun and as energy travels from one link to another only about 10% of the energy is transferred. Most energy is used by the organism and some is lost as heat. Energy is not recycled, it has to begin again from the sun.There is no word bank for this. Use the clues given in the diagram! Heat Heat Heat Heat Fill-in the blank by typing in the best correct answer. Spelling will count. Energy tends to enter an ecosystem from the sun as light and part of that energy is transferred from one organism to another with some being turned into heat. What is an ecosystem? Now that you have tried the worksheet, you can use these notes to check your answer before turning in the worksheet. Ecosystem notes
