Transcription

1 Oikos: House and Ology: to Study Scientific discipline in which the relationships among living organisms and the interaction the organisms have with their environments are studied. An Ecologist is someone who studies ecology.

2 The study of how living organisms interact with other living organisms. (Biotic) The study of how living organisms adjust to the nonliving factors in their environment. (Abiotic)

3 Something that is Living in an environment. Example: Animal or Plant

4 Something that is NOT living in a certain environment. Example: Water or Air

5 The interactions between Biotic and Abiotic Factors make up the environment. The interactions between Biotic and Abiotic Factors take place in the Biosphere

6 The Biosphere is the portion of Earth that can support life.

7 Plants Animals Fungi Bacteria Temperature Soil Water ph Salt Concentration Air

8 Organisms are adapted to surviving in the abiotic factors that are present in their natural environments. If an organism moves to another location with a different set of abiotic factors, the organisms might die if it cannot adjust quickly.

9 In five sentences, describe what you would see if you went SCUBA diving. Explain if they are Abiotic or Biotic.

10 Ecology: Study of how living organisms interact with their environment. Ecologist: someone who studies ecology Biosphere: the living portion of the Earth. Biotic: Living factor of an environment Abiotic: nonliving factor of an environment Aquatic: A biotic/abiotic factor that is associated with water. Ex: aquatic animals, aquatic plants, aquatic environments

11 Biogeochemical cycles

12 Biosphere: The portion of the earth that sustains life. Biotic Factors: Animals, Plants, Bacteria, Fungi Abiotic Factors: water, ph, temperature, sunlight etc.

13 A biogeochemical cycle is a repetitive process that recycles/reuses Abiotic factors in the environment. The exchange of matter through the Biosphere Bio- Life Geo- Rocks Chemical- Matter or Nutrient Cycle: Process

14 Matter is anything that takes up space and has mass. Matter provides nutrients needed for organisms to function Matter can be Biotic or Abiotic Example: Rocks, Plants

15 A Nutrient is a chemical substance that an organism must obtain from its environment A nutrient can be eaten or absorbed through the environment Example: food.

16 Evaporation Condensation Transpiration Precipitation

17 Photosynthesis Respiration Diffusion Combustion

18 Nitrogen Fixation Denitrification Decomposers

19 Phosphorus is a factor that limits growth of producers

20 There are many Abiotic factors that have a significant effect on living organisms Biogeochemical cycles are essential to the ecosystem Think: What might be some issues with a certain environment if one of these factors were low in availability? (Hint: Limiting Factor)

21 Ecological Organization

22 Organism Population Biological community Ecosystem Biome Biosphere

23 The lowest level of organization (when talking about ecological communities) Where an Organism lives is a Habitat. The Role an organism plays in it s environment is a niche.

24 Niche and Habitat

25 A Group of the same organism Organisms of the same population often compete for resources. What resources do organisms of the same population compete for? What might be an advantage to staying in a population? EX: School of Fish.

26 A group of interacting populations Organisms may or may not compete for resources within a biological community. Could this school be considered a Biological Community?

27 A biological community and all of the Abiotic factors affecting it. The size of an ecosystem can vary. EX: the Tropical Rain forest. The Human Mouth. When a Large group of Ecosystems overlap, this creates a Biome

28 What is a Biome? A large collection of ecosystems with the same climate and have similar types of ecosystems. All biomes combine make up the Biosphere.

29 1. Organism 2. Population 3. Biological Community 1. Lowest level of organization 2. Group of the same organism 3. A group of interacting populations

30 1. Ecosystem 2. Biome 3. Biosphere 1. A biological community and all the Abiotic factors that affect it. 2. A large group of ecosystems 3. All biomes on earth combined

31 Review: Niche Requirements for living space/access to nutrients. Competition

32 Competition occurs when more than one organism uses the same resource. What are some things that organisms may compete for? FOOD.**

33 Autotrophs: Plants Heterotrophs: Carnivores Omnivores Herbivores Detritivores

34 An Autotroph is an organism that collects energy from the sun
