5th Grade Science: Ecosystems
You will need to use these websites to fill out the worksheet I gave you. Clicking on the link might be easier than typing the entire website.
Try this link for grassland biomes.
Try this link for forest biomes.
Try this link for aquatic (water) biomes.
If you can’t find the information you need, you can use a Google search. For example, you could Google, biotic factors in freshwater lakes.
Students will compare these different ecosystems in terms of biotic and abiotic components.
Examples of biotic factors are the types and numbers of organisms living in the ecosystem.
Examples of abiotic factors are amount of sunlight, temperature, soil, nutrients, salinity, water clarity, or depth, all of which affect the variety and abundance of species.
