The interactions of the biotic and abiotic factors affect the ecosystem in countless ways. Biotic factors are the living components in the environment, such as plants, animals, fungus, bacteria, and etc.
Abiotic factors are the non-living components of the environment such as air, rocks, temperature, light, water, and etc. These are factors that have never been alive. Leather for example, is a biotic factor because leather actually comes from animals. Animals are obviously biotic factors of the ecosystem.
Both factors depend on each other to preserve an ecosystem. In other words an ecosystem cant function properly with both factors existing. For example, an ecosystem without water; eventually all plants will die, then the animals, then humans. We humans can't live without water. Another example is plants depend on light and temperature for the process known as Photosynthesis.
In this experiment we are exploring these topics. We are trying to figure out the effects of fertilizer on plant height and growth. Data shows that fertilizer does help in the speed of growth and height of plants. (www.fertilizer.com) According to the information shown on this website, fertilizer acts like a growth formula for plants.
Purpose:.
The affects of Liquid Fertilizer on the optimal growth of plants. This experiment examines the affects of fertilizer on the plants, and if the fertilizer does or does not promote plants growth. .
Hypothesis:.
The liquid fertilizer may speed up the growth of the plant. The plant might grow taller than a plant without fertilizer. A plant without a fertilizer might take a longer period of time to grow tall. .
Materials:.
- Two plant pots.
- A bag of soil (10 kg).
- One liter of Liquid Fertilizer.
- Seeds.
- A few Rocks.
- Two paper plates.
Procedure:.
1) The two pots were placed on a table.
2) Paper plates were put under the two pots.
3) The pots had holes in them, so the rocks were used to block the holes.
4) Pots were both filled with the same amount of soil, about 3 handfuls each.
