Presentation Transcript

  1. Environment • The physical surroundings of an organism, including all the conditions and circumstances that affect its development.

  2. Interaction • a relationship between parts of the environment.

  3. Biotic Factors • the parts of the environment that are living or were once alive. • Examples- dog, bone, rotting log

  4. Abiotic Factors • the parts of the environment that are nonliving • Examples: air, temperature, water, light, sand

  5. Niche • The role an organism plays in its environment. Its relationship with other organisms and with its physical surroundings.

  6. Habitat • The place where an organism lives.

  7. Ecosystem • A group of organisms and their physical environment • All abiotic and biotic factors that found a location suitable to make or find their habitat

  8. Freshwater Ecosystem TRIVIA: What would be an abiotic factor in this ecosystem?

  9. Symbiosis • a kind of partnership between two organisms in nature.

  10. Commensalism • a symbiotic relationship between two organisms in which one benefits and the other neither benefits nor is harmed.

  11. Mutualism • a symbiotic relationship between two organisms in which both benefit. Mutualism between ants, a caterpillar, and a flower in the American southwest. The caterpillar has a nectar organ which the ants drink from, the flower survives from the feeding caterpillar, and the ants provide protection for both the plant and the caterpillar.

  12. Parasitism • a symbiotic relationship in which one benefits(the parasite) and lives in or on another (the host, which is harmed) and takes nutrients.

  13. Symbiosis Commensalism Mutualism Parasitism

  14. Photosynthesis • The process of using sunlight, water, and carbon dioxide to make food (glucose). Green plants do this. Products

  15. Producers • Organisms that produce food for themselves and others.

  16. Consumers • Organisms that depend on other organisms for food.

  17. Herbivores • Consumers of only plants.

  18. Carnivores • Consumers of only meat.

  19. Omnivores • Consumers that eat plants and animals.

  20. Predator • Predator- A consumer that hunts or captures other organisms (prey) for food.

  21. Prey • an organism that is hunted or captured and eaten by another consumer. Prey

  22. Scavenger • Scavenger- A consumer of dead or decaying plants and animals.

  23. Decomposer   Bacteria and fungi that break down dead and decaying plant and animal matter and enrich the soil.

  24. Population • All organisms of the same species living in the same area.

  25. Community • All the populations of species living in an area.

  26. Food chain • A diagram showing how certain living things depend on one another for energy. Gives energy to… Gives energy to… Gives energy to… Gives energy to… Gives energy to…

  27. These ARE food chains:Grass  Cow  Human Acorn  SquirrelPlant plankton  WhaleDead leaves  Worm  Robin  HawkTree buds  Deer  Cougar

  28. These are NOT food chains: • Sun Daisy  Butterfly  Frog • Water Algae  Fish  Turtle • Plankton DDT Fish  Eagle • Algae  Minnow  Bass  Plastic fishing lure • Corn  Mouse  Snake Water

  29. Food Chain Rule #1Food chains only contain biotic factors. SUN NON_LIVING THINGS WATER PESTICIDES

  30. These are food chains: • Grass  Cow  Human • Acorn  Squirrel • Plant plankton  Whale • Dead leaves  Worm  Robin  Hawk • Tree buds  Deer  Cougar

  31. These are NOT food chains: • Cow  Grass  Human • Squirrel Acorn • Whale  Plant plankton • Worm  Dead leaves Robin  Hawk • Deer  Tree buds Cougar

  32. Food Chain Rule #2Food chains must start with a producer.

  33. Examples of Producers

  34. These ARE food chains: • Grass  Cow  Human • Acorn  Squirrel • Plant plankton  Whale • Dead leaves  Worm  Robin  Hawk • Tree buds  Deer  Cougar

  35. These are NOT food chains: • Grass  Cow Human • Acorn  Squirrel • Plant plankton  Whale • Dead leaves  Worm Robin  Hawk • Tree buds  Deer  Cougar • Remember  means “gives energy to…”

  36. Food Chain Rule #3Food chains have arrows that go from left to right. It shows the food “jumping” into the other organism’s mouth.

  37. TOP OF FOOD CHAIN SECONDARY CONSUMER PRIMARY CONSUMER PRIMARYPRODUCER

  38. Food web • A diagram showing as many food relationships as possible between living things in an area.

  39. Succession • Changes in an area that cause one group of organisms to be replaced by another.All rebuilt→ climax community

  40. Succession All rebuilt→ climax community
