Understanding Ecological Relationships and Energy Flow in Ecosystems

Explore the intricate web of relationships in ecosystems, from the sun as the primary energy source to the interactions between producers, consumers, and decomposers. Learn about biotic and abiotic factors, various types of consumer roles (like herbivores and omnivores), and symbiotic relationships such as mutualism, commensalism, and parasitism. Delve into concepts like the 10% rule of energy transfer in food chains and the recycling of matter in the environment, highlighting the delicate balance of life on Earth.

  2. This is the source of all energy in an ecosystem

  3. The sun

  4. This is the name given to all the living parts of the environment

  5. Biotic Factors

  6. Water, temperature, and air are this type of factors

  7. Abiotic

  8. This is the name given to organisms that make their own food, from solar energy

  9. Producers/autotrophs

  10. What is another name for a consumer?

  11. Heterotroph

  12. This is the type of relationship between a flea and a dog

  13. Parasitism

  14. Bacteria in the stomachs of cows help cows digest their food. We describe this as this type of relationship…

  15. Mutualism

  16. This word is used to describe how organisms interact with one another we define it as “living together”

  17. Symbiosis

  18. An orchid can use a tree trunk to receive extra nutrients, it does not hurt the tree by growing on it…this is an example of:

  19. Commensalism

  20. A lion may hunt a zebra. They belong to different trophic levels. Name what type of consumer the lion and zebra would be?

  21. Lion= secondary consumerZebra= Primary consumer

  22. What do the arrows represent in a food chain Grass Rabbit Fox

  23. Energy transfer

  24. This is the name given to organisms that eat both animal and plant material

  25. Omnivores(Tertiary Consumers)

  26. Animals that eat plants only are called

  27. Herbivores(Primary consumers)

  28. Organisms that include bacteria and fungi are called:

  29. Decomposers

  30. How many herbivores are in the food web above?

  31. Three: Grasshopper, squirrel and rabbit

  32. This is what we call anything that takes up space

  33. Matter

  34. Give an example of types of matter that get recycled in the environment

  35. Water, Carbon

  36. At In an energy pyramid, organisms at the top only get a certain amount of energy, because most energy is lost as heat and waste material. What do we call this rule?

  37. 10 % Rule

  38. What happens to all the matter that exists on earth?

  39. It gets recycled

  40. What process shown above, decreases the amount of carbon dioxide in the air?

  41. Photosynthesis

  42. As a predator population increases, what happens to the prey population?

  43. Decreases

  44. What do we call this type of growth?

  45. Exponential (J-curve)

  46. What is another name for carrying capacity ?

  47. (K)

  48. Space, births, mates, food are considered this type of factors….

  49. Density-Dependent

  50. What does the dashed line represent?
