  1. Ecosystems Definitions

  2. Definitions • Abiotic: Non-living physical or chemical factors in the environment; for example: air, sun, water and soil (minerals) • Biotic: Living components in the environment such as humans, plants, birds, microorganisms, and insects

  3. Definitions • Ecosystem: all the interacting biotic and abiotic parts of an area; an ecosystem can be large or small, but must contain all of the abiotic and biotic features.

  4. Organism: an individual animal, plant, or single-celled life form. • Individual : A single organism • Population: a collection of organisms of the same species found in a specific geographic area • https://www.youtube.com/watch?v=QI2ixJeIxEU

  5. Habitat: the natural environment where an organism lives • Community, also called biological community: an interacting group of various species in a common location.

  6. Food Web • The trophic level of an organism is the position it occupies in a food chain or Food Web (Trophic level info is bonus info for you) • Three Main Categories: (Gotta know this stuff) • Producer • Consumer • Decomposer

  7. Write this down… • Producer: organism that makes its own food using abiotic components such as water, air, nutrients, and sunlight • Consumer: organism that cannot make its own food; eats other organisms • Decomposer: organism that feeds on dead plants or animals; breaks complex molecules into simpler nutrients.

  8. Food pyramid ^ Consumers(Scavengers too) ^ Decomposers ^

  9. ProducersTrophic Level 1 • Organisms that make their own food using abiotic components such as water, air, nutrients, and sunlight • Green plants and Algae • Photosynthesis

  10. Primary ConsumerTrophic level 2 • These organisms can not make their own food energy. • Primary consumers are Herbivores, they eat plants and Fungi for food energy.

  11. Did you Know? Kilo Joule • Kilojoule[edit] • The kilojoule (kJ) is equal to one thousand (103) joules. Nutritional food labels in some countries express energy in kilojoules (kJ). • One square metre of the Earth receives about 1.4 kilojoules of solar radiation every second in full daylight • kJ are similar to Calories: 1 kJ = 0.2 Calories (Cals) 1 Calorie = 4.2 kJs.

  12. Secondary ConsumerTrophic level 3 • These organisms are predators that are either: • Carnivores – Eat smaller Herbivores • Omnivores – Eat plants and animals

  13. Tertiary ConsumerTrophic level 4 • These predators eat other predators • Carnivores.

  14. Apex Predator • A predator at the top of the food chain in their ecosystem • They are not hunted by other predators (other than themselves)
