• Concepts we will discuss (continued)
• Preservation vs. Conservation
• Carrying Capacity
• Food Chains

5
Concepts in Natural Resources

• Renewable Resource
• Resources that can be replaced by human efforts
• Can be Renewable forever depending on the
  management of the resource
• Example Forests and Forest Products

6
Concepts in Natural Resources

• Non-Renewable Resources
• Limited resources that cannot be replaced once
  they are gone
• Careful use and extend the length of their
  availability
• Example Petroleum and Petroleum products

7
Concepts in Natural Resources

• Environment
• All of the physical surroundings of a species

8
Concepts in Natural Resources

• Ecology
• Study of the complex relationships among living
  things and their environment

9
Concepts in Natural Resources

• Ecosystem
• Any partially self-contained environmental and
  living thing
• Example A lake, a large valley, or a forest

10
Concepts in Natural Resources

• Biome
• A major land area characterized by dominant plant
  life forms
• Established by altitude and rainfall

11
Concepts in Natural ResourcesBiomes (continued)
12
Concepts in Natural Resources

• Preservation
• An attempt to prevent the use of a natural
  resource
• Aim is to preserve or keep it intact as it is
  or was

• Conservation
• An attempt to use a natural resource in a way to
  minimize water
• Aim is to maintain the resource in as good of
  condition as possible

13
Concepts in Natural Resources

• Carrying Capacity
• The ability of an ecosystem to provide food and
  shelter for a given population.

14
Concepts in Natural Resources

• Food Web
• A group of plants and/ or animals
• related to each other by the fact that one feeds
  or depends for food on the next

15
Concepts in Natural ResourcesFood Web (continued)

• Pyramidal in shape
• Many producers
• Fewer Consumers
• Fewer still predators

16
Concepts of Natural ResourcesFood Web (continued)
17
Concepts of Natural Resources

• Producers
• Also known as autotrophs
• Make their own food

• Consumers
• Also known as hetertrophs
• Organisms that feed on other species

18
Concepts of Natural Resources

• Food Chains (Continued)
• Carnivores
• First-order Carnivores
• Carnivores that feed on herbivores
• Second-order Carnivores
• Carnivores that feed on first order carnivores

19
Concepts in Natural Resources

• Food Chains (continued)
• Omnivores
• All eaters
• These critters are both herbivores and carnivores

20
Concepts of Natural Resources

• Food Chains (continued)
• Predators
• Carnivores that feed on live animals
• Examples Owls

21
Concepts in Natural Resources

• Food Chains (continued)
• Prey
• Animals that are eaten by predators
• Examples Mice

22
Concepts in Natural Resources

• Food Chains (continued)
• Scavengers
• Critters that feed on dead organisms
• Both plants and animals
• Examples snails, crayfish, crow

23
Concepts in Natural Resources

• Food Chains (continued)
• Saprophytes
• Fungi that feed on dead organisms
• Examples Fungi, bacteria

24
Concepts in Natural Resources

• Food Chains (continued)
• Decomposer
• Break down and feed on non-living organic matter
• Examples Yeasts, molds
