Ecology is the study of organisms and their interactions with each other and their environment. Biotic factors, or living things, in an environment include animals, plants, and bacteria. Abiotic factors, or non-living things, in an environment include water, sunlight, air, temperature, soil, rocks, and sunlight. The hypothesis is if the right balance of biotic and abiotic factors are added to the bottle, then the ecosystem and the living things in the ecosystem will be able to survive. Moving forward, here is the background information on the biotic factors in this lab experiment. Betta splendens-Betta Fish, also referred to as the Siamese fighting fish, the Betta are very territorial and often aggressive towards other Betta’s and other fish. A Betta’s typical diet consists of small organisms…show more content… Betta’s are known for their vibrant colors passed down through generations of the fish family, they can change their colors depending on their feeling(agitation, stress,etc.). Betta’s are typically put in small environments, but they prefer large habitats that allow mobility as small containers can cause health issues. They also prefer water temperature to be about 75 degrees fahrenheit. Elodea-Anacharis, also known as Brazilian waterweed, is a very versatile aquarium plant. It is often held down by its roots planted in the ground. But can live floating in the water. It can live in cold or warm water climates, and survives with little light. Anacharis acts as a filter and absorbs fish excretion. Cosmos bipinnatus- Cosmos, are apart of the Sunflower family. They can grow to be 3-6 feet tall, and typically need 12 inches in between plants to enable proper growth. Cosmos can typically do without water for a certain amount of time, but need water regularly, and can grow in most regions that vary in conditions. Tagetes- Marigolds, The flower needs to be planted about 2 cm from each other with about ¼ of soil piled above
