1.) BIODIVERSITY a.) Please examine a vegetated area (in your backyard, a park, your school, etc). The area should be the size of a bicycle tire (0.7 m diameter). Spend at least 5 minutes examining your area. Actually do this activity outdoors. How many species do you count? Describe each species that you see. Is there any evidence that a species was once there? (3 points) b.) Describe the ecological niche of one of the species in your area. (3 points) c.) If you wanted to enhance the abundance of your species, how would you alter the abiotic or d.) If you were to shade this area (e.g. with an umbrella) permanently, how would the species biotic conditions? (2 points) distribution (all of the species and their abundance) change? Explain your reasoning. (2 points)Explanation / Answer
a) I counted 3 species. One is a flowering plant which is a herb called forb(eg.sunflower)The other is also a flowering plant but it resembles grasses called Rush, the other species is known as Sedge which also resembles grasses. These species are present from a long time because there is a wide distribution of this species all over the area.
b) Forb or sunflower habitat is mostly dry and open areas. This grows in sunny areas. These usually grow where the resources are abundant and thus fit into the ecological niche. This is tolerant to extreme temperatures.
c) To enhance the abundance of this species the abiotic factors especially sunlight is very important and other resources water,soil conditions and temperature has to be maintained properly. These are usually destroyed or grazed by goats and cattle which are biotic factors and this must be avoided. By altering these abiotic and biotic conditions this species can be enhanced abundantly.
d) If the area is shaded with an umbrella the plant do not get required amount of sunlight. When sunlight is not sufficient the plants do not get their food because photosynthesis do not occur. This results in withering and plant dies slowly. The species cannot multiply its number and it's distribution is affected.
