The 10% rule means that when energy is passed in an ecosystem from one trophic level to the next, only 10% of the energy will be passed on.
Plants use their stomata to take in Carbon dioxide and take out oxygen during photosynthesis. It's how they "breathe" if that makes it more understandable.
As we know that
<span>P total = pO +pH +pN</span>
<span>so</span>
P = P1 + P2 + P3
378 kPa= 212 kPa + 101 kPa + P(H2)
P(H2) = 65 kPa
partial pressure is 65
so correct option is A
hope it helps
Answer:
A.cultural norms that directly impact sustainable development : <em>social</em>
B.production and consumption of natural resources and manufactured goods. <em>Technological</em>
C: federal, state, and city agencies support sustainable development: <em>Public policy</em>
D: leveraged across all other domains to achieve sustainability objectives: <em>economic</em>
Explanation:
There are five domains of sustainable development. The social domain includes the cultural ethics which are different for every society and impact the sustainable development.
The technological domain includes all the recent advances which are used for sustainable development.
The Public policy domain includes the help that a federal or state government might give in developing a sustainable development.
Economic domain looks upon the economic value achieved through sustainable development.
Ecotourism
d. increases biodiversity by providing income to areas that might otherwise be destroyed
Explanation:
Ecotourism refers to visiting of undisturbed natural areas.
Ecotourism is different from other tourism on the fact that it does not involve visit to an area which is maintained by humans.
Ecotourists spots are allowed to grow naturally so that they can drag people who really want to enjoy the nature.
Ecotourist spots are protected areas and taxes are levied on them.
Ecotourist spots call for tourists and gives native people ,a way of earning.
This forces the people to maintain these spots and hence biodiversity is conserved.
