Answer:
The greenhouse and enhanced greenhouse effects refer to the return of approximately <u>80</u> percent and greater than <u>80</u> percent of the heat radiated by Earth.
Explanation:
During natural greenhouse effect :
. Solar radiation reaches the earth
. Re-radiation of heat occurs
. Less re-emitted heat
. More heath escapes into space
Hence the greenhouse effect refers to return of 80% of heat radiated by Earth.
While during Human Enhanced Greenhouse effect :
. Solar radiation reaches earth
. Re-radiation of heat occurs
. More re-emitted heat
. Less heat escapes into space
Hence the enhanced greenhouse effect refers to return of more than 80% of heat radiated by Earth .
<span>Trophic level—90% of energy consumed at trophic
level is used by the consumer for survival and reproduction. The remaining 10%
is transferred to the next trophic level. So the answer is 10,000 x 0.9
or 9,000 calories will be generally available
to primary consumer</span>
Reptile answer option no 1
Answer:
Vascular Tissues
Explanation:
Angiosperms higher flowering plants it is most diverse group in a plant kingdom nearly 300,000 species of flowering plants are found under this kingdom.The angiosperms have specialised cells and tissues that carry out their metabolic functions and evolved vascular tissues (xylem and phloem) that translocate the water and nutrient to all parts of the plant. They are terrestrial, root system absorbs water and mineral from the soil. the shoot system supports and leaves involved in the process of photosynthesis
