Pond Ecosystem Investigation Lab report By: Harshal Buradkar 9 grade Introduction A pond ecosystem consists of abiotic: light intensity of the water, depth of the water, and biotic: fish, plants, bacteria, algae, insects and etc. It also contains water and plants which is the most important part of the pond. Ponds are mostly shallow with the depth of 12-15 feet in which the sun rays can touch the bottom of the pond so that plants can grow. My aim is to find out how the plant cover affect the biodiversity of animal life in the pond. Experimental question How does the plant cover affect the biodiversity of animal life in the pond? Hypothesis Claim:- Most animals get food from plants around them. Some animals stay under plant cover because …show more content…
Water mites and water fleas etc. live among the stones and gravel in the shady part of the pond. These small invertebrates feed on algae. Sticklebacks enjoy the shade provided by the lily pads and feed on algae and small invertebrates. Twenty common newts feed in the pond. Toothed pond skaters hunt for small flies that become trapped on the surface of the pond. Emperor dragonflies fly over the pond in the summer and lay eggs on plant stems beneath the surface of the water.” According to another site, “Spirulina algae, which is often found in fish food, is packed with nutrients and is a natural color enhancer. A balanced diet also includes vitamin B, vitamin C, and digestive enzymes that helps pond fishes to stay healthy throughout the winter months. Experiments have shown that wheat germ will help goldfish and koi grow at a much more rapid speed, and it is also a natural source of vitamin E (a vitamin that helps with …show more content…
It shows what and how many different types of pond animal species there are in the pond. for example in experiment A there are 4 pond snails and in experiment B there are 6 pond snails. So the table and the graph give me a brief information on how many animal species and animals of that species I found in experiment A and B. So my research shows that my hypothesis was not clearly correct because their can be other possibilities but my research supports my hypothesis. My claim was that the more plant cover their is the less pond animals or insects there are and their will be different types of species of insects in different areas. In experiment A the light intensity was 365.30 lux, the Depth of the pond was 69 cm, and I found 22 animals and 9 different species of them and there was no plant cover. In experiment B the light intensity of the pond was 110 lux, and the depth of the pond was 64 cm, and I found 14 animals and 7 different species of them and there was 1 plant cover, a lily pad. This proves my hypothesis was
