Activities Producers and Consumers activity Google DCDSB. Click on the DCDSB website. Near the top of the screen, click on Students. Down the right side of the screen, click on the LaunchPad Learning Portal Login choice. Click on the sand-coloured Carousels tab. Click on the Grade 4 icon. Select the green S&T tab at the bottom, then select the Life Systems icon (picture of a nest). Use the left-right arrows that are on the screen to find the activity called Producers and Consumers Click on that icon. 1. How does the Sun-grass-cow food chain diagram explain how a food chain works? It shows how energy flows from the Sun, to the grass, to the cow as it is passed from one organism to the next 2. Why do we call plants producers? Plants don t consume other organisms, they have to produce (make) their own food 3. What is a primary consumer? Give an example. eats only plants is a primary consumer 4. What is a secondary consumer? Give an example. eats a primary consumer is a secondary consumer. 5. What is a tertiary consumer? Give an example. eats a secondary consumer is a Tertiary consumer. 6. Draw the food chain you created (with the Sun, leaves, caterpillar and robin). The Sun gives off energy in the form of sunlight. The Sun s energy is absorbed by the leaves. The leaves produce their own food from the sunlight in the form of sugars. The caterpillar consumes the leaves and absorbs the energy from them. The robin consumes the caterpillar and absorbs its energy
What is a Habitat? activity When you have finished the previous activity, go down to the bottom of the screen and click on what looks like a small screen with two yellow rectangles and one blue rectangle. Go back to the green S&T tab at the bottom, then select the Life Systems icon (picture of a nest). Use the leftright arrows that are on the screen to find the activity called What is a Habitat? Click on that icon. 1. fill in the chart below to describe the three habitat types you investigated Climate or conditions Plants there are like Animals there are like Animal examples Hot Tropical Coral Desert Rainforest Reefs Very hot in summer Warm the rest of the year Plants are small, with thick stems Trees are short and woody Animals are usually small and tend to be nocturnal Insects, reptiles and birds Hot and very rainy because it s close to the Equator Tall, broad-leaf evergreens Orchids, mosses and ferns, vines Birds, monkeys and snakes in treetops Insects, frogs, snakes on ground Colorful birds, spider monkeys, sloths, snakes, frogs, butterflies 2. Describe the conditions of freshwater lakes and mixed forests Climate or conditions freshwater lake Lakes freeze over in winter and warm up in summer Warm, clear, shallow ocean water in the Tropics where there is lots of sunshine Algae (microscopic plants) are the most common plant, followed by sea grasses Reefs home to small sea creatures Sponges provide shelter Small fish, crustaceans (eg. shrimp), sponges, anemones, sea horses, worms, sea cucumbers mixed forest 4-seasons: warm summers and cold winters Plants there are like Animals there are like Algae, reeds, water lilies and seaweed. Small or medium fish crustaceans, turtles and frogs, water insects Mix of deciduous and coniferous trees, eg. pine, hemlock, oak, maple Small flowering plants eg. trilliums, poison ivy, buttercups Small and large animals: some carnivores, some herbivores, and the rest omnivores Animal examples Snapping turtles, leopard frogs, Bears, deer, foxes, rabbits, blue bass, trout, crayfish, water beetles jays, eagles muskrats
3. How does a freshwater lake help deer and other animals? Freshwater lakes provide drinking water for deer and other animals 4. How does a freshwater lake help seagulls and other birds? Seagulls and other birds catch fish for food 5. How does a freshwater lake help mink and other animals? Mink and other animals catch crayfish and other lake animals for food 6. How does a freshwater lake help humans? Humans use lakes for recreation (swimming, fishing, boating, canoeing, waterskiing, etc. 7. How does a freshwater lake help local towns? Local towns process lake water to make it safe for washing and drinking 8. What are 4 sources of pollution that threaten our lakes? Industrial and human waste, atmospheric (air) pollution, invasive species, and agricultural waste 9. Give one example of how industrial and human waste threaten lakes? Industrial (chemical) waste can poison the water so it s absorbed by palnts and animals. Human waste can cause infections 10. Give one example of how atmospheric pollution threatens lakes? Chemicals in the air can come back down as acid rain that slowly changes lake water so some fish and plants can t survive anymore 11. Give one example of how invasive species threaten lakes? New species can disrupt the food chain and push older species out of the food chain 12. Give one example of how agricultural waste threatens lakes? Waste from farm animals can cause bacteria levels to rise. Chemicals from fertilizers can be absorbed by fish and plants in the lakes
Identifying Consumers activity When you have finished the previous activity, go down to the bottom of the screen and click on what looks like a small screen with two yellow rectangles and one blue rectangle. Go back to the green S&T tab at the bottom, then select the Life Systems icon (picture of a nest). Use the left-right arrows that are on the screen to find the activity called Identifying Consumers? Click on it. 1. Why are all animals called consumers? They all have to eat (consume) other things to survive 2. What are the three types of consumers? Carnivores, herbivores and omnivores 3. What is a carnivore? Give an example. Carnivores are animals that only eat other animals. ex. wolf, polar bear, tiger 4. What is an herbivore? Give an example. Herbivores are animals that only eat plants. ex. deer, cow, caterpillar, elephant 5. What is an omnivore? Give an example. Omnivores are animals that only plants AND animals. ex. parrots, raccoons, grizzly bear 6. Fill in the boxes with at least 5 kinds of animals for each consumer type. Carnivore Herbivore Omnivore Lion, shark, weasel, polar bear, seal, owl, eagle, fox, whale Rabbit, squirrel, cow, elephant, deer, sheep, moose, giraffe, zebra Grizzly bear, turtle, raccoon, pig, mouse ostrich
The Food Chain Game activity Find the activity called The Food Chain Game? Click on it. 1. a) What are producers? Producers are organisms capable of making their own food and energy. b) Why are plants considered producers? They produce their own energy from the Sun through photosynthesis. 2. a) What are consumers? Consumers are organisms that other things by eating and digesting them. b) How are consumers different from producers? Consumers cannot produce their own energy. They have to eat to get energy. c) What are the three types of consumers? Carnivores, herbivores and omnivores 3. a) What are herbivores? Herbivores are animals (consumers) that eat only plants b) List 4 examples of herbivores? Horses, elephants, cows, and rabbits 4. a) What are carnivores? Carnivores are animals (consumers) that mainly eat meat (other animals) b) List 3 examples of carnivores? Sharks, lions, frogs, owls, and hawks 5. a) What are omnivores? Omnivores are animals (consumers) that eat both plants AND animals. b) List 2 examples of omnivores? Humans and bears (not polar bears) are omnivores 6. a) What are decomposers? Decomposers are organisms that eat decaying (dead) organisms, breaking down matter into nutrients b) List 3 examples of decomposers? Bacteria, mushrooms, and other fungi break down dead plants and animals 7. Beside each type of living thing, state whether it s a producer, consumer, decomposer, carnivore, herbivore, or omnivore. Then give proof Organism Category I know it s one of these because. Mushrooms decomposer They grow on fallen trees and other dead plants Owl carnivore They catch and eat small animals Cat carnivore Catches and eats small animals in the wild Grass producer Doesn t eat other things, gets energy from the Sun Tree producer Doesn t eat other things, gets energy from the Sun Shark carnivore Catches and eats other fish in the ocean Girl omnivore Eats both plants (veggies or salad) and meat
