2 Ecosystems Video

3 Ecosystem All of the organisms living in an area together with their Physical Environment. Examples: Coral Reef, oak forest, Vacant lot

4 ECOLOGY Is the scientific study of the interactions between organisms and their environments

5 Habitats The place an organism lives. Every habitat has specific biotic and abiotic factors; if any of these factors change then the habitat changes.

6 Abiotic & Biotic

7 Biotic vs. Abiotic Factors Environment Biotic Factors Abiotic Factors Animals, plants, people, birds Water, sunlight, soil, rocks, wind, temperature

8 Biotic vs. Abiotic Factors Biotic = living (BIO = life) Abiotic = nonliving Biotic factors are all of the living things in an environment. Abiotic factors are all of the nonliving things in an environment.

9 Biotic vs. Abiotic Factors What were some of the living things, or biotic factors, that you listed? Trees and plants, birds, grass, bugs, people, dog What were some of the nonliving, or abiotic factors, that you listed? School building, light poles, houses, cars, street

10 Biotic or Abiotic? Biotic!

11 Biotic or Abiotic? Abiotic!

12 Biotic or Abiotic? Biotic!

13 Biotic or Abiotic? Abiotic!

14 Biotic or Abiotic? Abiotic!

15 All organisms are what biotic or abiotic? Biotic!

16 Create a 2 column list, Abiotic & Biotic. While watching the movie, write down as many items in the appropriate columns.

17 As a Team Create a master list that combines all your answers. The team with the most gets a point.

18 Do biotic and abiotic factors affect each other? If there is no water can anything grow or survive? If it is extremely cold one winter, will that affect whether an animal makes it? So, abiotic and biotic DO affect each other. Even though water and temperature are not living things, they DO affect living things!

19 Answer these 1. What does biotic mean? 2. What is an example of a biotic factor in an environment? 3. What does abiotic mean? 4. What is an example of an abiotic factor in an environment? 5. Give an example of how an abiotic factor can affect a biotic factor.

20 A Hierarchy of Interactions Ecology can be divided into several increasingly Biosphere comprehensive levels Biome Ecosystem Community Population Spices Organism

21 Levels of an Ecology The Universe Galaxies Solar Systems Earth Biosphere Biomes Ecosystems Communities Populations Spices Organisms Organs Tissues Cells Protoplasm Molecules Atoms

22 The Biosphere Biosphere is the global ecosystem The Universe Galaxies Solar Systems Earth Biosphere Biomes The biosphere is made up of the parts of Earth where life exists. Ecosystems Communities Populations Spices The biosphere extends from the deepest root systems of trees, to the dark environment of ocean trenches, to lush rain forests and high mountaintops.

23 Biomes The Universe Galaxies Solar Systems Earth A biome is an area of the planet that can be classified according to the plants and animals that live in it. Temperature, soil, and the amount of light and water help determine what life exists in a biome. A biome is different from an ecosystem. An ecosystem is the interaction of living and nonliving things in an environment. A biome is a specific geographic area notable for the species living there. A biome can be made up of many ecosystems. For example, an aquatic biome can contain ecosystems such as coral reefs and kelp forests.

24 Ecosystem Is concerned with ecosystems, which include all the abiotic factors in addition to the community of species in a certain area The Universe Galaxies Solar Systems Earth Biosphere Biomes Focuses on energy flow and the cycling of chemicals among the various abiotic and biotic factors Ecosystems Communities Populations Spices Organisms Organs Tissues Cells Protoplasm Molecules Atoms

25 Community The Universe Galaxies Solar Systems Earth A group of various species that lives in the same place and interact with each other. Is concerned with communities, assemblages of populations of different species Focuses on how interactions between species affect community structure and organization Bisosphere Biomes Ecosystems Communities Populations Spices Organisms Organs Tissues Cells Protoplasm Molecules Atoms

26 Populations The Universe Galaxies Solar Systems Earth All members of the same species that live in a particular location at the same time. Is concerned with populations, groups of individuals of the same species living in the same area Concentrates mainly on factors that affect population density and growth Bisosphere Biomes Ecosystems Communities Populations Spices Organisms Organs Tissues Cells Protoplasm Molecules Atoms

27 Species The Universe Galaxies Solar Systems Earth Bisosphere A group of organisms that can mate to produce fertile offspring. Biomes Ecosystems Communities Populations Spices Organisms Organs Tissues Cells Protoplasm Molecules Atoms

28 Organisms An individual living thing The Universe Galaxies Solar Systems Earth Bisosphere Is concerned with the evolutionary adaptations that enable individual organisms to meet the challenges posed by their abiotic environments Biomes Ecosystems Communities Populations Spices Organisms Organs Tissues Cells Protoplasm Molecules Atoms
