Environmental Science

1. Environmental Science

2. Studying the web of life All living things are connected in a web of life. Scientists who study the connections among living things specialize in the science of Ecology.

3. Ecology The study of the interaction between organisms and their environment.

4. An environment has two parts. Biotic- Living factors in the environment; things that are alive. Abiotic- nonliving factors in the environment.

5. Identify if they are bioitic or abiotic

10. Organization in the environment At first glance, the environment may seemed disorganized. The environment can be arranged into different levels.

11. Organisms a living thing such as a plant, animal, or bacterium.

12. Populations A group of individuals of the same species that live together in the same area at the same time.

14. Community All of the populations of different species that live and interact in an area.

18. Ecosystem A community of organisms and their nonliving environment.

21. Biosphere The part of earth where life exists.

24. Let’s ask the experts Tim and Moby. http://www.brainpop.com/science/populationsandecosystems/ecosystems/

25. All living things need energy to survive. Organisms in any community can be divided into three groups based on how they obtain energy. Let’s examine to see how energy passes through these groups in an ecosystem.

26. There are three groups Producers Consumers Decomposers

27. Producers Organism the uses sunlight directly to make food. They do this by using a process called photosynthesis.

28. Autotrophs Are known as producers. They are the green plants that produce their own food.

29. Photosynthesis Plants are able to capture light energy from the sun and convert it into food.

30. Consumers Organisms that eat the producers or other organisms for energy. There are several kinds of consumers; herbivore, carnivore, omnivore and scavengers.

31. Hetetrophs Are known as consumers in the environment. They consume the energy of other organisms.

32. Herbivore A consumer that eats plants.

34. Carnivore A consumer that eats animals.

36. Omnivore A consumer that eats a variety of organisms.

37. Omnivore Greater Dwarf Lemur

38. Bonobo

39. Scavenger An animal that feeds on the bodies of dead animals.

41. Decomposers Organisms that gets energy by breaking down the remains of dead organisms.

43. Let’s watch Tim and Moby http://www.brainpop.com/science/populationsresourcesandenvironment/foodchains/

44. Food Chains and food webs Food chain- A diagram that represents how the energy in food molecules flows from one organism to the next.

45. Food web A complex diagram representing the many energy pathways in a real ecosystem.

46. Energy Pyramid A diagram shaped like a triangle showing the loss of energy at each level of the food chain.

47. Habitat The environment where an organism lives.

51. Niche An organism’s way of life and its relationship with its abiotic and biotic environment.

52. Types of interaction Most living things produce more offspring than will survive. An organism, such as a frog, interacts with biotic or abiotic factors in its environment that can control the size of its population.

53. Interaction between organisms There are four ways that species and individuals affect each other: competition, symbiotic, predator and prey. Let’s look at each one.

54. Competiton When two or more individuals or populations try to use the same resource, such as food, water shelter, space or sunlight.

55. Prey An organism that is killed and eaten by another organism.

56. Predator An organism that eats all or part of another organism.

58. Symbiosis A relationship in which two different organisms live in close association with each other.

60. Mutualism A relationship between two species in which both species benefit.

62. Commensalism A relationship between two organisms in which one organisms benefits and the other is unaffected.

63. Barnacles adhering to the skin of a whale or shell of a mollusk: Barnacles are crustaceans whose adults are sedentary.

64. Parasitism A relationship between two species in which one species benefits and the other is harmed.
