1.) BIODIVERSITY

a.) In order to study local biodiversity, place a hula hoop (real or imagined) (a hula hoop is a 1 m diameter circle) around a vegetated area in your backyard (park, school).  [This is a real assignment, not an imaginary one.  Do it!  Spend at least 5 minutes examining your area. Examine it carefully.]  How many species do you count?  Describe each species that you see.  Is there evidence that species was once there? (2 points)

b.) Select one of the species in the hula hoop. Describe its ecological niche.  (3 points)

c.) If you were to increase the temperature of your plot by 3 degrees Celsius for a month (using automatic heaters; making your plot 3C warmer than the surrounding area at all times), how would the species distribution (and abundance) change?  Explain your reasoning.  (2 points)

d.) Pick one species that you found in your hula hoop (could be the same or different from the one in (b), could be plant or animal). How can you alter abiotic or biotic conditions to promote the success of that one species at the expense of the others? (3 points)

Answer:a

In an any vegetated area we can see several types of species such as plants, animals, fungi, bacteria etc. For example the cutting eaten leaves gives an idea of the presence of grasshopper. Likewise we can see butterfly over there.

Answer: b

For example butterfly, it flies over flowers and suck the juice for their food. And grasshopper, it eats the leaves of plants.

Answer:c

As temperature plays an important role for survival of any specie in the ecosystem, therefore some species are familiar to sustain in low temperature whereas some of them are familiar with high temperature.

Answer: d

To promote any specie, there should be maintain a familiar environment in terms of biotic and abiotic as well. Such as for biotic factors there should be some bacteria which supports the growth of plants and in terms of abiotic factors there should be familiar temperature, water, sunlight etc.
