2. Definitions Of Biotic Factors Producers: Organisms that are capable to make their own food only plants can do it with the help of photosynthesis. Producers: Organisms that are capable to make their own food only plants can do it with the help of photosynthesis. Consumers: Organisms that eat producers to get energy from them. Consumers: Organisms that eat producers to get energy from them. Decomposers: Organisms that eat decaying matter. Decomposers: Organisms that eat decaying matter. Scavengers: Organisms that eat only dead animals. Scavengers: Organisms that eat only dead animals.

8. Types of Interactions Predation: When one organism kills another for food. Predation: When one organism kills another for food. Competition: Is the struggle between organisms to stay alive. Competition: Is the struggle between organisms to stay alive. Symbiosis: A close relationship is called symbiosis. At least one organism is benefitted. Symbiosis: A close relationship is called symbiosis. At least one organism is benefitted.

9. Predation As I said predation is when an organisms kills for food. In the grassland biome we will have three or four predation relationships though I will show you only 2. As I said predation is when an organisms kills for food. In the grassland biome we will have three or four predation relationships though I will show you only 2. 1 st example of predation is when a Lion kills the Giraffe for food. 1 st example of predation is when a Lion kills the Giraffe for food. 2 nd example of predation is when the Cheetah kills the Zebra for food. 2 nd example of predation is when the Cheetah kills the Zebra for food.

10. Competition Well competition is the struggle of 2 organisms for something. Well we too need this in our biome and we have that I will show you one example or multiple so you know we have competition going on right here. Well competition is the struggle of 2 organisms for something. Well we too need this in our biome and we have that I will show you one example or multiple so you know we have competition going on right here. 1 st example of competition is when the Cheetah competes vs.. the Hyena for the Impala and Zebra.(food) 1 st example of competition is when the Cheetah competes vs.. the Hyena for the Impala and Zebra.(food)

11. Symbiosis Relationships There are only three types of symbiosis relationships and they are these. There are only three types of symbiosis relationships and they are these. Mutualism: When both species are benefitted. Mutualism: When both species are benefitted. Commensalism: When one species obtains food or shelter from the other species and the other species is not harmed or benefitted. Commensalism: When one species obtains food or shelter from the other species and the other species is not harmed or benefitted. Parasitism: When one of the species is harmed. Organism that is helped is called parasite and the one being harmed is called the host. Parasitism: When one of the species is harmed. Organism that is helped is called parasite and the one being harmed is called the host.

12. Examples of Symbiosis Relationships Mutualism: An example of mutualism in the grassland biome is the Zebra and the Bacteria because the bacteria helps break down food for the zebra and the bacteria gets food and the zebra digests more easily. Mutualism: An example of mutualism in the grassland biome is the Zebra and the Bacteria because the bacteria helps break down food for the zebra and the bacteria gets food and the zebra digests more easily. Commensalism: An example of commensalism in our biome is between the Acacia and the Baboon because the baboon sleeps on the acacia tree and is benefited and the acacia tree does not mind. Commensalism: An example of commensalism in our biome is between the Acacia and the Baboon because the baboon sleeps on the acacia tree and is benefited and the acacia tree does not mind. Parasitism: An example of parasitism is the Giraffe and the Tick because the tick drinks blood from the giraffe and is benefitted and the giraffe is harmed and is not benefitted. Parasitism: An example of parasitism is the Giraffe and the Tick because the tick drinks blood from the giraffe and is benefitted and the giraffe is harmed and is not benefitted.

13. Info of the Grassland Biome on Outer Space Day length: 25 hours Year Length: 370 days Precipitation: 600mm – 2,500mm Temperature: -5° - 20°C Sunlight: Over 80% of sunlight each day Soil: Very porous, very thin layer of humus and is very fertile. Types of landforms: Very few trees, placid environment (humid), rivers, flowers,,mountains, slopes.
