Why should humans be concerned about rarity of species, not just extinction rates?.

1 answer:

7 0

Because we coexist in ecosystems with rare species and depend on them for our existence and quality of life, we should be worried about the rarity of species.

The entire group of organisms and the natural setting in which they live together make up an ecosystem. Through nutrient cycles and energy exchanges, these biotic and abiotic elements are interconnected. Through photosynthesis, energy enters the system and is absorbed into plant tissue. Animals are crucial in the transport of matter and energy through the system because they consume plants and one another for food. They also have an impact on the biomass levels of microorganisms and plants.

Decomposers are organisms that break down dead organic matter, releasing carbon into the atmosphere and facilitating nutrient cycling by transforming nutrients held in dead biomass into forms that are easily utilizable by plants and microorganisms. External and internal influences affect ecosystems in different ways.

A change in the dollar value of the British pound from $1.60 to $1.50 represents A. an increase in the pound price of British

hram777 [196]

Answer:

Option (B) is correct.

Explanation:

1 pound = $1.60

1 pound = $1.50

So, there is a depreciation in the value of pound relative to the dollar and appreciation in the value of dollar relative to the pound.

Now, suppose a resident of united states purchase some quantity of goods(say, 20 shirts) from the seller in United kingdom.

Price of each shirt = 2 pounds

Hence,

Before the change in exchange rate, then the buyer have to pay in dollars:

= 20 × (2 × $1.60)

= 20 × 3.2

= $64

After the change in exchange rate, then the buyer have to pay in dollars:

= 20 × (2 × $1.50)

= 20 × 3

= $60

Hence, the amount paid by the resident of united states reduced because of the fall in exchange rate. Now, they have to pay less for the same amount of commodities. This shows that there is an appreciation in the currency of US relative to UK.

Suppose Nicholas owns a business making Christmas tree ornaments. Currently, he makes 300 ornaments a month. At this level of pr

Fudgin [204]

<u>Solution and Explanation:</u>

1. MC = Cost of raw material + Cost of time

MC = 5 plus (10 divide by 2)

MC = $10

2. TFC = $300

Q = 300 , AFC = TFC/Q = 300 divide by 300 = $1

3. His profit maximizing output would be higher

Reason: P = MR = $15 , MC = $10

Since MR > MC, and at the profit maximizing point MR = MC, it is better for Nicholas to increase his output.

4. His profit maximizing output would be higher

Reason: P = MR = $15 , MC = $4 + $5 = $9

Since MR > MC, and at the profit maximizing point MR = MC, it is better for Nicholas to increase his output.
