The document outlines the objectives, activities, and content of a lesson on ecological relationships. The objectives are to enumerate five ecological relationships, define key terms like mutualism and parasitism, categorize relationship photos, and apply knowledge to examples. Students will be split into groups to define terms, create organizers, match words to meanings, categorize photos, give examples, and identify impacts of relationships. The content then defines ecology, environments, biotic and abiotic factors, levels of ecological organization, niches, producers, consumers, decomposers, energy transfer between trophic levels, ecological pyramids, food chains, food webs, biological magnification, and relationship types like predation, competition, and symbiosis.
Food chains and webs show the transfer of energy and nutrients between organisms in an ecosystem. A food chain traces the flow of energy from producers like plants through consumers at different trophic levels. Herbivores are primary consumers, carnivores are secondary or tertiary consumers. Decomposers break down dead organic matter and cycle nutrients. Food webs are more complex than chains, with many interconnected feeding relationships between species. Ecological pyramids graphically represent numbers, biomass, or productivity at each trophic level, with producers at the base and apex predators at the top. Disturbances like bioaccumulation of toxins can disrupt ecosystem balance.
The document summarizes programs and projects from various science and technology councils under the Department of Science and Technology (DOST) in the Philippines.

Scientists classify matter based on its composition into mixtures, elements, and compounds. Mixtures are two or more substances that are not chemically combined and can be separated physically. Elements are the simplest substances that cannot be broken down further, while compounds are pure substances made of two or more elements chemically bonded together. Mixtures can be further classified as homogeneous if the substances are uniformly mixed throughout, or heterogeneous if they are not. Solutions are homogeneous mixtures where one substance dissolves in another.
