1 Abiotic/Biotic

2 Tuesday April 10, Name 3 things that are not living and have never lived. 2. Name 3 things that are living or have lived. 3. Name 3 types of freshwater reservoirs.

3 Biotic vs Abiotic Factors Biotic: Anything that is living or has lived. Abiotic: Anything that is non-living. In your notebook draw a Venn diagram and label one side Biotic and the other Abiotic.

4 Biomes Write down the similarities and differences between the three pictures.

5 Biomes Based off of the similarities you wrote down for the pictures, write down a definition for a freshwater biome Freshwater biome: Large communities of plants and animals centered around waters with less than 1% salt concentration. Examples: ponds, lakes, rivers, streams, wetlands.

6 Wednesday April 11, Define biotic and abiotic. 2. Define a freshwater biome. 3. Name 3 biotic and 3 abiotic organisms in a freshwater biome.

7 Biome vs Ecosystem Freshwater biome: Large communities of plants and animals centered around waters with less than 1% salt concentration. Ecosystem: A biological community of interacting organisms and their physical environment.

8 Freshwater Ecosystems 3 types of Freshwater Ecosystems: Lentic: slow moving water, including pools, ponds, and lakes. Lotic: faster moving water, for example streams and rivers. Wetlands: areas where the soil is saturated with water for at least part of the time.

9 Label the biotic and abiotic organisms

10 Research: Choose 1 of the Freshwater Ecosystems (Lentic, Lotic, or wetland) and answer the following questions in your notebook. 1. Name 3 organisms that thrive (do well) in your ecosystem? 2. Name 3 organisms that cannot survive in your ecosystem? 3. Name 3 biotic and 3 abiotic organisms in your ecosystem. 4. Draw a picture of your answers to number 3 and draw arrows showing how your organisms interact.

11 Thursday April 12, Describe a lotic freshwater ecosystem. 2. How is energy transferred from a plant to an animal? (think back to the carbon cycle) 3. What is the difference between a biome and an ecosystem?

12 Freshwater Ecosystems Collect the research questions that we did yesterday from 2 people that did not have your topic yesterday. *By the end of the 7 minutes you should have all 4 answers for Lentic, Lotic, and Wetland freshwater ecosystems.

13 Energy Transfer in Ecosystems Producers: organisms that can make their own energy through biochemical processes (photosynthesis) Consumers: organisms that eat organisms from a different population. (herbivores, carnivores, omnivores) Decomposers: break down dead plants and animals. They also break down the waste (poop) of other organisms. (bacteria, fungi, some snails and insects)

14 Energy Transfer in Ecosystems Put the cards in order so that it looks like a food chain. Make sure to label which chain is the terrestrial (land) food chain, and which is the marine (water) food chain. When you have finished, try to place the cards that say producer, primary consumer How would you describe the different consumers (talk with your partner)

15 Check yo Self

16 Energy Transfer in Ecosystems Why are there typically only 4 levels in an ecosystem?

17 Energy Transfer in Ecosystems

18 Energy Transfer in Ecosystem In your notebooks think of an ecosystem (desert, forest, ocean, ect). 1. Draw a producer, primary consumer, secondary consumer, tertiary consumer. 2. Label the consumers as herbivores, carnivores, or omnivores. 3. Draw arrows showing energy transfers (don t forget the energy lost)

19 Friday April 13, What percentage of energy is lost from a secondary to a tertiary consumer? 2. Give an example of a tertiary consumer. 3. Name 2 abiotic factors.

20 Experiment: (Periods 1-3) Problem: How do abiotic organisms change an ecosystem? (Periods 4-7) Problem: How do biotic organisms change an ecosystem?

21 Experiment: Hypothesis: (per 1-3) If we change the temperature of the ecosystem then (per 4-7) If we change the amount of plants then...

22 Experiment: Fill out the paper up to the procedure question.
