Subject Matter: Forest Ecosystem References: Into the Future: Science and Health 6 pp. 74-76 EPOW pp. 114-117 Family Encyclopedia p. 353 Materials: manila paper, marker, pictures of a forest ecosystemIII. Procedure1. Preparation1. Review: Relationships in an Ecosystem1. Review Drill1. Developmental Activities1. Motivation: Poem about a Tree by Joyce Kilmer TREESI think that I shall never seeA poem lovely as a tree.A tree whose hungry mouth is prestAgainst the Earths sweet flowing breast;A tree that looks at God all day,And lifts her leafy arms to pray.A tree that may in summer wearA nest of robins in her hair;Upon whose bosom snow has lain;Who intimately lives with rain.Poems are made by fools like me, But only God can make a tree.

1. Presentation The poem tells us about a tree. You learned that there are many trees and other plants in the forest. Are forest resources important to us? Lets find out.1. Activity/DiscussionProblem: Why is a forest important to us? a. Sharing ideas on the importance of the forest.1. List down the ideas that were shared.1. Report output in class.1. Generalization A forest is a large ecosystem. Plants in the forest use sunlight, nutrients in the soil and air to make food. Different kinds of animals feed on plants and other animals. A Forest ecosystem is important because: 1. They are homes to wildlife. 2. They serve as watersheds and protectors of soil. 3. To people, they are sources of lumber and other materials. 4. Forests clean the air of carbon dioxide, which could, otherwise, trap heat in the atmosphere. 5. The trees in the forest release a great amount of oxygen in the air needed by animals and man.

I. Objective: Explain how overpopulation disturb the interrelationship in an ecosystem.II. Subject Matter: How Overpopulation Disturb an Ecosystem Ref. Into the Future: Science and Health 6 pp. 84-92 EPOW 6 pp. 132-135 Internet Materials: flashcards, pictures of organismsIII. ProcedureA. Preparation1. Review: Importance of a Forest Ecosystem2. Review DrillB. Developmental Activities1. Motivation: Call some pupils to arrange the organisms on the chalkboard to form a food chain2. Presentation: Unlock the terms organism, population and overpopulation. Present to the pupils the problem, What might happen if there is an overpopulation of secondary consumers in the food chain?3. Activity/DiscussionProcedure1. Let each group, study the illustration of two aquariums on p. 91 of their science book.2. Let the pupils infer what might happen to the fishes in the two aquarium.a. In which set-up, A or B, will there be more abundant dissolved oxygen for the fishes?b. In which set-up is space limited for the fishes to move?c. In which set-up will there be more competition for food among the fishes?d. In which set-up is there an overpopulation of fishes?e. Will overpopulation affect an ecosystem?f. How did overpopulation disturb the aquarium ecosystem?3. Does overpopulation affect the interrelationship of organisms in an ecosystem?4. How will overpopulation of one kind of consumer affect the interrelationship in a food chain?5. There are more animals and man than plants in an ecosystem. How will this situation disturb the oxygen-carbon dioxide cycle?6. What are the harmful effects of overpopulation in an ecosystem?

4. Generalization Overpopulation is a condition where an organisms number exceed the carrying capacity of its habitat. It does not depend only on the size or density of the population but on the ratio of population to available sustainable resources. Clean water, clean air, food, shelter, warmth and other resources are necessary to sustain life. Overpopulation of a particular kind of animal species can cause imbalance in an ecosystem. It occurs when an ecosystem is unable to support the existing wildlife because there are too many of them. Due to lack of food and limited space, overpopulated species wander into other ecosystems causing disruption. It disturbs the natural cycles in an ecosystem. It can result to lack of food, space and other needs of overpopulated organism resulting to ecological imbalance and destruction of the environment.5. ApplicationStudy the food chain that was arranged in the chalkboard and answer the following questions

1. What will happen to the rice grains if there are too many rats in the rice field?2. What might happen to the rats if there is an overpopulation of snakes?3. What is the effect of too many snakes that will eat the rats to the number of rice grains?4. What can you say about the number of snakes if there are too many eagles in the ecosystem where they belong?5. If there are many eagles that will eat snakes, what is its effect to the number of rats?6. Evaluation Answer the following questions. Explain the effect of overpopulation in the following Situations.1. There are few grasses and many deer in the forest. a. Deer will go to another place to look for foodb. Deer will have more food to eat.2. There are more tigers than zebras .a. It will disrupt the food chain where tigers and zebras belong.b. It will cause a balance in the ecosystem.3. There are a lot of crocodiles than fishes in the pond.a. The crocodiles will compete for food.b. The crocodiles will have enough food to eat.4. Too many fish in a ponda. Limited spaceb. More oxygen5. More secondary consumers than primary consumersa. It will disturb the interrelationships of organisms in a food web.b. It will ensure the survival of organisms in a food web.
