Title: Concepts in Natural Resources


1
Concepts in Natural Resources
  • Natural Resources II
  • Mr. Cole

2
Concepts in Natural Resources
  • Concepts we will discuss
  • Renewable Resource
  • Nonrenewable Resource
  • Environment

3
Concepts in Natural Resources
  • Concepts we will discuss (continued)
  • Ecology
  • Ecosystem
  • Biome

4
Concepts in Natural Resources
  • 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
