    1. 1. Ecological Niches
    2. 2. Ecological NichesHabitat: The naturalhome of an organism. Itprovides refuge andfood.
    3. 3. Ecological Niches An ecological niche is the role (functions) of a species in an ecosystem and its habitat.
    4. 4. Ecological NichesThe ecological niche of a species includes:1) What it feeds on2) What feeds on it
    5. 5. Ecological Niches3) How the species behaves in its environment4) All the factors that the species needs to survive,remain healthy and reproduce
    6. 6. Ex. What is the ecological niche of black bears? – Live in forests. – Feed on nuts, berries, insects, and small animals. – Fed on by blood-feeding insects and parasites. – Help carry seeds of berries for long distances (in their digestive systems) and expel them allowing the seeds to grow.
    7. 7. Energy Flow in Ecosystems
    8. 8. Energy Flow in EcosystemsAlmost all energy onEarth comes fromradiant energy – theenergy from our sun.
    9. 9. Energy Flow in Ecosystems Radiant energy that is absorbed by land and water is called thermal energy. It keeps Earth at its present temperature range.
    10. 10. Energy Flow in EcosystemsThe portion of radiant energy we can see is called light energy.
    11. 11. Energy Flow in EcosystemsProducers can collect this energy and turn it intochemical energy.
    12. 12. Energy Flow in EcosystemsThis process is called photosynthesis:carbon dioxide + water + light energy  sugar + oxygenSugar is a source of high energy.
    13. 13. Energy Flow in EcosystemsWhen a consumer eats a producer, it releases the energyfrom the sugar in a process called cellular respiration:sugar + oxygen  carbon dioxide + water + light energy
