  1. Ecology

  2. ECOLOGY - a term coined by a German biologist Ernst Haeckel, 1866 - From the greek: oikos = the place where one lives logos = study of Ecology then, is the study of how organisms interact with each other within their natural setting/ environment

  3. ABIOTIC and BIOTIC factors Abiotic = non-living factors e.g. sunlight, temperature, wind direction and strength Biotic = factors caused by the presence or role of other living things e.g. interaction of plants with insects in their environment

  4. Non-living parts of your community (Abiotic) • Buildings • Roads • Bodies of water • Land • Wind • Sunlight

  5. Abiotic factors affect distribution of species •                         Abiotic factors of interest include: • - Temperature (range from 0 to 45 C) • - Water • - Sunlight • - Wind (increases heat & water loss) • Rocks and soil • Amount of oxygen in the water

  6. Stewardship Acting in a way that involves taking personal responsibility for the management and care of something Issue A problem or concern facing the earth’s climate, environment, resources, etc

  7. Sustainability • living organisms like plants, animals, bacteria, insects and other living things that can interact and reproduce indefinitely • For ex: Long-lived and healthy wetlands and forests are examples of sustainable biological systems.

  8. SILENCE OF THE FROGS ACTIVITY http://www.pbs.org/wnet/nature/episodes/frogs-the-thin-green-line/video-agricultures-effect-on-frogs/4848/ What are Endangered Species? An endangered species is a POPULATION of organisms which are AT RISK of becoming EXTINCT because it is either few in numbers, or threatened by various factors. Some of the factors are: • Loss of species habitat due to accommodating for growing human population • Pesticide use • Hunting and trading • Pollution

  9. EXAMPLES OF ENDANGERED SPECIES: SEA OTTER DHOLE SIBERIAN TIGER
