By what process does nitrogen enter the living components of ecosystems?

Greeley [361]

The second process of the nitrogen cycle after nitrogen fixation in the atmosphere. Nitrogen enters the living components through a process called nitrogen assimilation. This is the absorption of nitrite ions in plants roots or through digestion of plants enriched with nitrogen.

Which best explains the role of chlorophyll in photosynthesis?

Tasya [4]

Answer:

B. absorbs energy from the Sun

Explanation:

This is what Chlorophyll does. Chlorophyl's main job is to collect the energy from the sun, and then, it can help the plant make the glucose (plant food).

Look at picture for more explanation. (with picture explanation coming below Extra info)

Extra info:

I learned in my class, that Chlorophyll is on the top most layers under the epidermis and dermis of the leave's skin. There is first the Epidermis, then there are lots and ltos of chloroplast cells, then there are chlorophyll cells in it.

With Picture explanation:

1st image:

The first image shows the leaf's structure. First, you can see the epidermis (on the top), then you can see all those light green round-edged-boxes, those are all the chloroplast cells, then, inside them, are darker green cells, they are the chlorophyl cells.

2nd image:

The second image shows the structure of a chloroplast cell.

The giant light green part on the outside is the chloroplast, then inside that, there are green things, which are the chloroplast, (here they are called thylakoid, because that's the scientific word for it). And then, the other things shown are just extra info.

Answer:

Complete the following problems using the equation:

Students are not required to memorize this formula but must know the meaning of the symbols:

D = diversity index

N = total number of organisms of all species found

Σ = the sum of

n = number of individuals of a particular species

D is a measure of species richness. A high value of D suggests a stable and ancient site, and a low value of D could suggest pollution, recent colonization or agricultural management. The index is normally used in studies of vegetation but can also be applied to comparisons of animal (or even all species) diversity.

Example: A lake contains 934 brown trout, 733 smallmouth bass, 34 catfish, 2003 carp,

234 steelheads, and 32 northern pikes.

Fish

Number (n)

n(n-1)

Brown Trout

934

934 x (934-1) = 871422

Smallmouth Bass

733

733 x (732) = 536556

Catfish

34

34 x (33) = 1122

Carp

2003

2003 x (2002)=4010006

Steelheads

234

234 x (233)=54522

Northern Pike

32

32 x (31)=992

Total (N)

3970

= 5 474 620

= 3970 x 3969 = 15 756 930

D = = 2.88

Simpson’s Diversity Index – Practice Problems

When comparing two or more samples, the location with the larger D has a greater amount of diversity. Note that a higher total population does not indicate higher diversity.

An area of the Black Forest in Germany contains 134 pitch pines, 24 douglas firs, and 53 red pines.

A meadow contains 1532 chestnut oaks, 342 black cherry trees, 12 white ash trees, and 1022 yellow birches.

Your backyard contains 12 fleas, 34 aphids, 84 ants, 93 beetles, and 1 butterfly.

An African National Park contains 15 lions, 94 giraffes, 1000 wildebeests, 50 elephants, and 5 hyenas.

Mindo (a city in Ecuador) has 832 toucans, 392 red headed barbets, 3 golden headed quetzals, 500 tanagers, 899 parrots, and 50 white capped dippers.

Answer the following questions in your workbook:

Calculate Simpson’s diversity index for each location. Include the table in your workbook.

Distinguish the differences in diversity between two locations listed above.

Explain what may lead to those differences.

Outline the significance of the Simpson’s Diversity Index. You may refer to the following online resource and your textbook to help outline your ideas - http://www.countrysideinfo.co.uk/simpsons.htm

¿Como se regula la prolactina?

morpeh [17]
